6.2L Engine Tick

Replaced injectors. My injectors did not have the white foam piece at bottom. These came with all new seals and bottom foam seals. Great deal.

New take offs that are cheap. No way I would pay a dealer $2000 for this!

Is Elite Engineering a good catch can?

Yes, I have the Elite can single port in and one out back to the engine with the large can you can use ball valve on bottom to purge. I also have the clean side separator and it works but probably could live without. Build quality is pretty good and have had no problems works very well.

My 2017 Denali Ultimate with the 6.2 had the same lifter tick. After several visits to the dealer for that and other issues, they finally did a comparison to one on the lot, the difference was significant. They went into and found the number seven lifter had collapsed. The truck had new lifters installed and a new cam @ 15700 miles. The sound was gone. Long story short, after that my steering failed and I almost wrecked the truck. Called GM and initiated a buy back. They bought the truck back and I made the mistake of getting the same truck, but a 2018 with the standard bed. This truck started making the same noise at around 17k. Took it in and was told that it is fine. I'm over 26k at this point and the tick has gotten worse.... I hope the son of a bitch grenades! Going to go back to the shop soon. I will never get another one of these trucks... If I want engine noise, I'll get a diesel, but most likely I'm just not buying GM again...
