Lifter Issues

[D Ennis]

Just had 4 lifters replaced along with a bent pushrod on a 2015 6.0 with 32 K miles. What the hell is happening with these engines?

The best answer to your question IMO is they make a bad one occasionally.

Could have been worse.

+1 above.
Problems like this with the 6.0 are rare.  Search this and other boards.  Sounds like you just got a bad one.

You've got a strange one.  6.0 isn't related to the new engines, so they can't be grouped into the "what the hell is happening" category IMO.

My 09's LY6 ate a lobe off the cam after a lifter destroyed it... A bunch of the other lobes were all buggered too.  Truck had like 58000 miles... stuff happens.

What oil were you using?

I am a mechanic in a Buick-Gmc dealer and have not seen many valvetrain issues on the 6.0's. The engines with AFM is another story altogether.I just finished a camshaft,lifters,vlom,and one cylinder head on a 2015 yukon with a 5.3 that had 37,000 miles on it Wednesday and today got a 2016 Yukon XL with 31,000 miles on it running on seven cylinders and making alot of valve train noise on the right bank, I pulled that valve cover off and have a broken exhaust valve spring on number 6 which is an AFM cylinder.It is almost always a cylinder with deactivation which either break the lifter or flatten the cam out.Both engines were clean inside and obviously maintained. We are seeing alot of theses lately.I am waiting on parts to finish this one Monday and hopefully it is just a valve spring on this one.

Did you over rev it ?

 

The 6.0 is a pretty bullet proof engine.

You can't really over-rev them lol.  Mine routinely turns 6000 rpm with the stock cam..... with the 216/226 on a 114 LSA I am stabbing in the heap it will probably get bumped to 6500 lol.

I have 2014 gmc Denali with 6.2. I took it to dealer because motor was ticking. It has bad lifter. It only has 48,000 miles and I don't haul anything. I am filing complaint with gmc. From what I am hearing, it is a common problem. The commercial so says precision. Yeah precision my ass!!
