Blown lml headgaskets

[elliottw]

Hey of you gm techs seen any lmls with blown hg lately? We've had 3 2014s in the last few weeks. The one last week made it the longest, just over 12k miles the other two had under 10k miles. Must have been a bad week at the gasket factory or something? They were all 3500 drw sold to oilfield companies. Pretty crazy stuff! Any of you guys have any input?

Were the water pumps bad on any of the 3 trucks?

I'll ask on Monday about the pumps. As far I know the only problem with all of them was gaskets only.

We had that one with 123k on it that Caleb did for us and found 5 cracked pistons! H&S, deletes and towing ext heavy.

These are all stock and all of these ones work hard from day one but that seems like there should be some sort of factory flaw to have them all fail so early?

Not if there pushed to there limit every day I say to tell owner to back it down

We just had a LML 3500 in for a set of head gaskets. Low miles and truck was driven easy and all stock.

I haven't seen one personally at the dealer but I do know there is a TSB out for them leaking.

Only one I've seen is if one is out to replace them both. Have a number for it?
