had that noise on my '04 Sierra 5.3. It was junk in the lifter from the oil change place never changing the damn filter - it was full of junk. I was lucky, Pulled the valve cover, rocker, push rod, shot Chemtool or gumout down into the lifter and down the pushrod (I only had one bad one but did the rest on that side too) Did a oil flush too, noise went away and never came back. There are some you-tube videos on it as well - good luck. It wasn't actually that hard at all, I'm not a master mechanic by any means, just your average joe that if I can do it to save a chunk of change, I will. I put it as about the same skill set as changing the water pump, it's harder to get all the harness clips off without breaking them than anything else

Damn, Glad to hear you fixed the issue. He's going to have it checked tomorrow morning. We will definitely keep this in mind. Thanks

It was taken to the dealer where my brother bought it. The "tech" was giving him the run around. the tech was trying to blame my brother for not servicing it or using cheap gas. My brother bought it used in May. He had the routine maintenance done at a shop, not himself. Still, the "tech" didn't have a definitive answer. he told my brother that they MAY have to open the engine to have a look. So far they have had it in the shop for 6 days and no good sign.

sorry to tell you but these trucks are pretty big pieces of crap. In the same boat is you. GOt a 2010 denali 6.2 with cam and lifters out at 80K


why GMC can't make a 50-60 thousand dollar truck that wont last over 100k without major engine issues is beyond me.

It's my brother's truck. It now has a little over 60k miles. They said "we don't really know what it is. we will most likely have to open the engine and possible check the pistons and/or lifter".

I agree it sounds like a lifter did you find out yet?
