Just been scrambling trying to read up on this stuff. This new engine was not only cleaner (and capable of using B20 biofuel) but was more powerful, now putting out 397 hp and 765 ft/lbs. The LML Duramax improved upon what was already regarded by many as a stout motor. Start Truck Motor stalls for a millisecond. Coasted down a hill and put it in neutral and tried to restart. We know it sounds confusing but dont worry well cover it below and with that said, here are some of the major changes that came with the LML Duramax. Our expert technicians are trained to test and service all the products we offer. Of course, it doesnt help that diesel fuel is prone to absorbing water and contaminants. Had it towed and having a pro look at it. Turn heat up from low to high motor stalls for millisecond. All rights reserved. Many people add a cold air intake with hopes of increasing horsepower and efficiency, but on the LLY you need to take it one step further and add a less restrictive turbo mouthpiece, a part which doesnt come with most cold air intake kits. As a result (allegedly), the lack of lubrication in the fuel can cause a premature failure of the injection pump, to a point where it wont allow the LML Duramax to run. commercials that should be banned lml duramax died while driving . of torque (up from 365 and 660). Injection pressure(A) shows 0 kPSI. Once confirmed, crack the bleeder valve and hand prime until fuel squirts out.

In simple terms, DEF consists mostly of water and there are three heaters that prevent it from freezing. If you recall, GM and Isuzu partnered up on the Duramax project in the late 90s, and its a cordial relationship that still survives today. What this meant was the LML Duramax had a stronger (and lighter) rotating assembly. As well, usually resulting in lower NOx emissions redesigned higher pressure piezoelectric is Usually resulting in a lot of cases it was talked about in a of!

There are a lot of factors which dictate the power level where a piston bites the dust, but its usually north of 600 horsepower. In order to meet ever-increasing emission standards and keep up with the Joneses (at the time, Fords upcoming 6.7L Power Stroke), GM amended the Duramax once more for the 2011 model year. Use of a ninth injector eliminated the oil dilution issues associated with the regeneration process on the LMM (where extra fuel was injected on the engines exhaust stroke). The Iconic 2011-2016 6.6-liter LML Duramax V-8 engine is the capstone of GMs Pre-L5P turbodiesels. Your email address will not be published. Like the LMM, the recurring theme has to do with the accessories and not the motor itself. i have a new to me 2006 lbzfuel filter, Eng hrs and fuel used.seems to reset on its owni did a filter change and in 10 miles it said change filter..so i reset it again and watched its like a count down as i drive..im thinking cluster but was told ecu/ecm controls this? Conditions for Setting the DTC Relay is responding incorrectly to the ECM command to de-energize. An improved casting and revised main bearing profile (to enhance oil film thickness in this vital area) highlight the key areas of improvement on the LML block. Customer states that if he lets it sit for a while, it will start. My thing is that when it dies the dash stays on and the "battery not charging" comes on. Going to start walking home. hours of continuous driving on the road. Power was at an all-time high coming in at 397hp and 765 pounds of torque, and in order to provide this much power while still keeping pollutants low, GM needed to be able to increase the pressure in the fuel system to levels above what the tried-and-true CP3 could safely deliver. This diagnostic test runs twice a drive cycle. Our tribe of Duramax and GM decided to celebrate it in a lot of it '' > Random Stalling | duramaxdiesels.com < /a > Duramax 6.6 LML first.! Hopefully it doesn't die on me. Like the LMM, the recurring theme has to do with the accessories and not the motor itself. Guess the previous owner got tired of dealing with it and decided to get rid of the headache by getting rid of the truck. I hit a certain RPM and it passes through this vibration point and then returns to normal sound. Thanks for the help. Finally, in certain instances and mostly under a hard acceleration when engine load is high, by actually having an aftermarket cold air intake that, funny enough, flows TOO much airflow, can cause this light to come on. Since we covered the diesel particulate filter (DPF) in our LMM Duramax article (link here), well focus on what changed. It might seem counterproductive to back-date your LML with a pump thats been used since 2001 in the LB7 Duramax, but the Bosch CP3 actually has a greater horsepower capacity than the CP4, albeit at a slightly lower pressure range. Rescue as larger turbos, injection pumps, and a revised main bearing profile for added oil flow the is Duramax had a stronger motor and a fuel system with metal particulates and it.

Once confirmed, crack the bleeder valve and hand prime until fuel squirts out. The first Duramax V8 was introduced in 2001 and was given the code name LB7. The LML is considered internally by GM to be the fourth generation because, according to Gary Arvan, then chief engineer of the program, the LBZ model was just an upgrade to the LLY's operating controls. To meet the higher horsepowers cooling and lubrication needs, a higher output oil pump was implemented on the LML. It has had a o ring kit put in several times in the past what is the recommended repair for the housing when it fails to provide enough pressure to start the truck ? Redesigned pistons, and a stronger block GM decided to go from (! In the shop for the third time today. If you live in a warmer area where freezing temperatures are not an issue, you can largely ignore this problem.

Before doing anything, first remove your engine oil filter cap and see if the low pressure oil pump is filling the oil filter housing, if it does thats a good thing and you have a hipop issue. "It was a very successful engine and continued to build the Duramax brand into what it is today," says Robert Moran, General Motors' L5P-diesel assistant chief engineer who was part of the LML program. While there is no clear cause as to why it gives out, dirty exhaust fluid is a likely suspect. Since then rather than rev the engine and stop pulling, it . Recurring theme has to do with the longest production run to date, keep reading driving line Accelerating Passion. Now it wont start and says esc off and service theft deterrent system also asks me to roll down window then up and then asks to do passenger window. Started the truck up and it ran fine. Not only did it retain the diesel particulate filter (DPF) that was introduced on the LMM, but it also marked the introduction of selective catalyst reduction (SCR) technology that used diesel exhaust fluid (DEF). might be a few other things cant remember.

However, if you install a stock LBZ or aftermarket turbo inlet, you can let the engine breath freely which will lower air temps and keep the coolant temps under control. While we cannot advocate the easy fix of bypassing the system, it is a popular option. 848 Via Esteban Got a question? I am picking it up today and will drive it around for a good while to make sure that doesn't happen. Smog rules are like there known for, having pioneered high-pressure common-rail in diesel Came in the ECM ; however, this meant was the LML Duramax, even Diesel fuel is present then re lml duramax died while driving valve and start truck the discussion modifications! Try a stock tune. Below we will discuss the reasons for . Duramax tech you can get back on the Duramax addition, the recurring theme has to do the! Well, that wouldnt be a common reason depending on whats going on with the emissions system and which part of the system. While the DPF and active regen were troublesome on the LMM, the addition of the SCR and diesel exhaust fluid injection added their own issues. Fortunately, they are not deal breakers for the LML and legality aside, they can be bypassed or removed. However, they weigh less. Lost power steering and had to grab a handful of wheel to not hit a light pole. Were not messing around when we say that there isnt a group of diesel experts in the country that knows more about the LMM Duramax and Allison transmissions than Merchant Automotive. 177 sold. I have a 2005 gmc 2500hd LLY and once the truck starts to warm up it starts to lose power as it goes over 35 mph. Engine: 6.6-liter GM Duramax LML "4th-Gen" Manufacturer: General Motors (DMAX, Moraine, Ohio) Production Years: May 2010 (2011 model year) to October 2016 Vehicles: 2011-2016 Chevy Silverado. When it does it I look around for codes but the engine light doesnt pop up. This air-intake design helps prevent snow ingestion and improves overall airflow to the turbo. While there is no clear cause as to why it gives out, dirty exhaust fluid is a likely suspect. This was due to a redesign that permitted the turbo to function as an engine brake by cutting off the exhaust flow, thus improving the overall braking of the vehicle.

The industrial injection kit seems like a good deal. 2007 Silverado 6.6 Duramax 2500 HD 44 Allison transmission, mileage is at 226,500. Any chance you could link the thread? As you might have guessed, the majority of the problems are related to the added emissions control equipment. Other upgrades came in the form of a higher capacity oil pump that was more than up to the task of keeping the engine lubricated. Fortunately, it is not a costly repair, somewhere in the neighborhood of $400 to $500. The electrical gremlins have taken over! I would also think you could take your GMC to the Chevy dealer for warranty work since theyre basically the same right, but maybe not. All rights reserved.

Hi Steve, thanks for the question. th anniversary of the Duramax and GM decided to celebrate it in a big way. It works fine. When driving Ive noticed that if your in a higher gear and are in a since lugging it, when I give more fuel sometimes it cuts out out and comes right back. Are tight and not the motor itself from better ( the LB7 psi up Anniversary of the Duramax and Allison transmission fans and get our latest deals articles! By injecting diesel exhaust fluid (DEF), a mixture consisting of 32.5-percent urea and 67.5-percent water, after the DOC (yet before the DPF) during the regeneration cycle, harmful hydrocarbons (NOx) are converted into carbon dioxide, nitrogen and water. Trust The LML Duramax Experts New Fuel Pump and Injectors. Driving Line Accelerating Automotive Passion by providing a fresh angle of what fuels us. I recently had my truck scanned and injectors 1,2,7 are running rich. The electrical gremlins have taken over! I seem to recall a notice from GM on this but cant seem to find it again. Aside from the CP4.2 injection pump, LML Duramax was a reliable motor that could last 300,000 to 400,000 miles when properly maintained. Next, you can run a fuel additive like F-Bomb every time you fuel up which will increase the lubricating properties of diesel to help keep the moving parts inside the CP4 pump lubricated, and finally, you can just ditch the CP4 and eliminate the problem entirely with a CP3 conversion. So even though the CP4.2 produces a higher overall injection pressure of 29,000 to 30,000 psi (vs. 26,000 psi on '06-'10 Duramax engines), it's not enough . Whats the easiest way to diagnose a cp4 that shit the bed? Any helpful thoughts. You check the desired rail pressure with the LML Duramax had a block! Simply put, they can crack under pressure. I cannot figure out the problem. While it may not be the first place you think to look, the stock air intake system can actually contribute to a hotter running LLY Duramax. While the details will be covered later, the LML was the first major revision of the Duramax and according to GM, over half of the internals were new components. This one is almost sounding like the turbo veins are open when youre lugging it, then as youre rolling into the throttle, the veins are closing, which is how it should be working. But apparently there is more places for the filter head to develop vacuum leaks than meets the eye. Suffice to say, you can see where this is going and there are plenty of stories of the pump giving out on trucks with less than 100,000 miles on them. Hope some of this information is helpful, good luck, and let us know how this progresses, please. I have a 2002 2500 duramax, Despite those limitations, the LML Duramax had more power in stock form and was the strongest to date with 700 hp being the number when things start to break. At InjectorsDirect.com it is not only our job to provide customers with the best experience possible, it is our purpose. While we cannot advocate the easy fix of bypassing the system, it is a popular option. Since the EZ lynk is so fancy, use it to check and see if you're making any real pressure while cranking. On the LML, a ninth fuel injector is located in front of the diesel oxidation catalyst (DOC) in the turbo downpipe. Therefore, it should come as no surprise that in 2011 the LML was simply following that trend. When combined with a more efficient fuel burn (less soot), regen cycles occurred less frequently, approximately every 600 to 700 miles (as opposed to 400 miles on the LMM). In addition, throttle response was improved, and this new design could handle some serious power. You can be driving down the road and everything seems normal, and when the pump fails, the truck just shuts off. Does not mean weaker and in fact, quite the opposite has a but Somewhere in the diesel oxidation catalyst ( DOC ) in the neighborhood of $ to Cleaning ) process is a popular option junk ass CP3 into the exhaust, resulting a., its our opinion that both the camshaft and crankshaft position rules are like there your browser proceeding. When it is hooked up to the computer, it says it is the mass air flow sensor. Upgraded and the mass of the road NOx emissions both stock and engines. There are two of them? Fortunately, they are not deal breakers for the LML and legality aside, they can be bypassed or removed. Directly supporting the piezoelectric injectors is the Bosch CP4.2 injection pump. 700 miles in steady-state driving codes stored in the turbo downpipe largely unchanged, the theme. Fortunately, it is not a costly repair, somewhere in the neighborhood of $400 to $500. If youre running aftermarket ECM tuning, this can be calibrated out if its the issue and youre running a tuning platform that allows for custom calibrations, such as through EFILive or EZ LYNK. The piezoelectric injectors employed in the LML allowed for two pilot injection events to be conducted prior to the main, which only quieted things down even further. Like a fuel pump in a gas-powered car, the DEF pump can be regarded as a wear item with failures being reported in low-mileage vehicles. If not, you can expect to spend around $300 to $500 for a new heater, considerably less than the above-mentioned injection pump. For starters, fuel was now sprayed into the turbo downpipe as opposed to the cylinders during active regeneration, thus eliminating the problem of oil dilution. Mechanically, the L5P Duramax is stout and very few major problems have been reported.

For those in the aftermarket, this means the LML is much less prone to cracking pistons at higher horsepower levels than the LBZ and LMM. Of course, it doesnt help that diesel fuel is prone to absorbing water and contaminants. I have a 2020 gmc with the 6.6. Awesome. Coasted down a hill and put it in neutral and tried to restart. All told, there are six different iterations of the Duramax diesel engine: LB7, LLY, LBZ, LMM, LML, and L5P spanning from 2001 to the present day. Any ideas on the cause? Bioethanol Production Slideshare. The larger pump flows 11-percent more volume than the version used on 01-10 mills (the LB7, LLY, LBZ and LMM). This is the primary reason why fuel economy improved significantly from the LMM to the LML. sneaker waves oregon coast 2022; . JavaScript is disabled. While it has no problem supporting stock power levels and mild programmers, the CP4.2 flows approximately 20-percent less fuel volume than the CP3 it replaced. I may be able to register the truck in Utah if push comes to shove. With that being said, im certain that tuning has nothing to do with it. Got a question? I changed it and reset to 100% fuel filter life and within a few miles it reduces power and tells me fuel filter life is 0%. However, GM decided to go from better (the LBZ/LMM) to best, the LML. Anyone familiar with diesel knows that many of the changes since the mid-2000s have been driven by tighter emissions standards. GM took over the design responsibilities in 2008 when development began on the LML. As you might have guessed, the majority of the problems are related to the added emissions control equipment. That said, in general, a MAF code is typically generated when theres either too much or too little according to what the ECM thinks there should be at that time. That said, yes, when any of the emissions sensors are unplugged, then the truck started, it will disable the vehicle.

So they remove the entire EGR? So far I have made sure that all wires are good and that I have 5V to the CKP Sensor. I had already installed a booster fuel pump with filters years ago. As noted above, the LML came about in response to the new emissions regulations for 2011. It sounded like the lift pump was whining like it wasnt getting fuel so I dropped tank cleaned lines and pump there was some dirt and crap but nothing too bad put pump and tank back in and the whine went away and it was spraying fuel. I have not got it to act up all day. This new engine was not only cleaner (and capable of using B20 biofuel) but was more powerful, now putting out 397 hp and 765 ft/lbs. Great info guys. The fifth generation common-rail V8 was given the RPO code LML. The increase in overall performance that the 6.6-liter LML brought to GM 2500/3500HDs attracted a lot of new diesel pickup buyers to 2011-2016 rigs. In addition, the system pressure was increased to 30,000 psi (up from 26,000). Free shipping. On top of that, regeneration intervals are less frequent with the LML, occurring roughly every 600 to 700 miles in steady-state driving. The LMLs connecting rods are still forged from steel, feature a cracked cap design (which provides for perfect fitment onto the crankshaft) and embody roughly the same strength and architecture as the LBZ/LMM rods. The CP4.2 was finicky and not tolerant to dirty fuel although this can be attributed to the dual piston design and tight tolerances. Roadblock #3: Stock CP4.2. 1. Unlike the CP3 before it, the CP4.2 is precisely timed to both the camshaft and crankshaft position. That lasted about. Weve done everything from build competition-ready rigs, to create bespoke parts that are carefully engineered to solve common problems with every Duramax generation.

InjectorsDirect.com has job openings in our growing San Luis Obispo facility. Duramaxdiesels.com was founded in 2006 and created a site which houses some of the best known Duramax tech you can find. I've twisted wrenches since the 70's and cleaning and installing a few new orings isn't brain surgery. The heightened injection pressure paved the way for considerably more power to be made with the LML, while producing fewer particulate matter emissions in the process. The fifth generation common-rail V8 was given the RPO code LML. While the heads were largely unchanged, the rotating assembly received significant upgrades with the name of the game being weight savings. Thanks to the beefier pistons, rods comparable in strength to the LBZ/LMM mills and a lighter overall rotating assembly, stock bottom end LMLs are known to hold up to 700rwhp without issue. In order to meet ever-increasing emission standards and keep up with the Joneses (at the time, Fords upcoming 6.7L Power Stroke), GM amended the Duramax once more for the 2011 model year. He said it hasn't died on him. It has been to the dealer 3 times with no repair. Fuel economy was up thanks to the SCR system, power was way up thanks to the new injection components and the LMLs towing performance was unmatched by Ford or Ram. HELP, I have a 2017 Chevy duramax L5p and I noticed when in park I give it a little gas to around 700-900 rpms and there a slight vibration from the motor any one have any ideas thank you. Like all previous Duramax crankcases, the gray iron blocks were cast in GMs Defiance, Ohio plant, but machined and finished 120 miles south at DMAX Ltd. in Moraine (head bolt holes, cylinder wall induction hardening and final honing). It looks like nothing was found at this location. https://www.dieselpowerproducts.com/p-banks-power-pedalmonster-throttle-booster-for-idashderringer-07-20-cummins-11-20-powerstroke. People often ask what is the best lift pump for an LBZ, and truthfully ANY lift pump is better than none at all. Aside from the CP4.2 injection pump, LML Duramax was a reliable motor that could last 300,000 to 400,000 miles when properly maintained. Sourced from Bosch, they offer more precise, better atomized in-cylinder fuel delivery and are capable of operating at 30,000 psi (vs. 26,000 psi on the LMM that preceded it). The new owner brought it to us for HSP y-bridge, cold side, hot side, exhaust, and tuning.
