Does anyone know where I can download a copy of the official bulletin from GM about the valve spring issue, especially for the 6.2 just in case there are separate ones. I think it would be good to have on hand just in case.

thanks in advance!

Looking for my paperwork (wife loves "putting stuff away") which will likely have more info

 

TSB is PIP5752A

 

 

22 SEPTEMBER 2020

 

#PIP5752A: Service Engine Light misfire engine noise With DTC P0300 P0106 P0506 - (Sep 22, 2020)

 

Subject: Service Engine Light misfire engine noise With DTC P0300 P0106 P0506

 

Involved Region or Country North America

 

Condition

 

A Vehicle may have a concern of service engine light, misfire and engine noise with possible of DTC P0300 P0106 P0506.

 

Cause

 

Possible broken valve spring.

CorrectionDuring inspection if you determine that the engine has a broken valve spring it will be necessary to perform a cylinder leakage test on the affected cylinder.

 

If no cylinder leakage is observed it will be necessary to replace all valve springs on both banks if the vehicle is built between June 1, 2020 to September 15, 2020. Note: This only applies to the 6.2L engines RPOs L87, LT1, LT4 and LT2. For all other engine RPOs L82, L84 and L8T just replace the affected valve spring.

 

If you determine that engine has cylinder leakage it will be necessary to inspect further to determine the extent of the engine damage to determine correct repair required.

 

Important: All valve springs will be requested back for further analysis and inspection.

What dates are the 6.2 motors supposed to be affected?

I'm not sure what the current date range is, it was June 1 2020 through I think mid October, then was revised into September. I'm not aware of any further revisions.

The farging GARBAGE that GM gets away with selling for premium money. Totally avoidable, just poor vendor quality control, driven by the DESCENDING price scale to suppliers.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      That should answer the maximum depth difference between the stock and the PPE so its not hugely lower. As to the PML pan, they don't make any claims that it fits the L8T with the same transmission and in fact leave their information confusing, however on the surface it says "for Duramax" and so its hard to say. I know a while back and not sure which brand it was that specifically stated that the extra capacity pan that particular company made did NOT fit the gas version.

      Installed Bilstein 5100's on my 2024 2500HD - Worth it - VIDEO + GIVEAWAY Inside

      By fondupot · Posted

      There are several versions of the 5100's. Some for stock height, some for leveled, some for lifted.    Side note. I finally had a chance to tow with my 30' gooseneck with about 10,000 lbs of material on it this past week. Hands down the 5100's made the trailer towing much more stable and comfortable. I even had 10 cmu blocks in the bed. What a difference over the stock shocks.

      According to PML, the stock pan is 4.3" deep - (PML info): Dimensions: at deepest area, PML pan is 7 inches, stock pan is 4.3 inches    PPE is 5.4" so roughly 1.1" deeper than stock

      I had not realized that PPE has come out with a version of a cast aluminum oil pan specific to being able to fit onto the 10L1000 with the L8T engine sometime this spring. I was doubting that anyone would come out with something beyond what Dorman had in more of a direct factory pan swap. I see from one comment that is on the PPE site that they found the pan to be tighter to install then the factory unit and having to flex the exhaust down to fit it. I didn't lookup any specs if they have any as per how much lower it hangs but as it holds more oil and has fins outside the pan it would no doubt hang a certain amount lower.    I looked back at the site and they do have some depth measurements to get a rough comparison to the factory pan total height or hang down if you will at the front and rear of the pan so that will give a good idea how much further down this pan would end up being for ground clearance issues.    2024-2026 GM 6.6L Gas 10L1000 Heavy-Duty Cast Transmission Pan – Pacific Performance Engineering

      I'm in constant amazement over the number of people that do oil maintenance by how they feel, what they were told, what materials cost, what brand A claims vs brand B.     Come to think of it, this behavior isn't exclusive to oil. 🤔 They drive this way too. 😬   There is a 20 plus page thread on BITOG on Mobil 1 Advanced Clean vs Valvoline Restore and Protect it would be amusing if it were not so........humanly pitiful.   Last Sunday we were are sitting at services and listening to a speaker talk about Jesus parable of the wide and narrow gates and he said something that hadn't dawned on me but totally fit the way people in general are about just about everything. He said there are so few people on the narrow path leading to a good reward not because the the narrow gate was hidden or hard to find but because the wide gate leading to a bad end it so darn easy and uncomplicated to follow!!!
