I haven't seen any reports of a C8 Z06 engine failure in a long time. This thread is over a year old at this point. There is about 10,000 of these cars on the road now. If there were widespread engine failures people would be talking about it.

Exactly why I think this thread should mirror the sticky thread in the C8 General Forum and just name it "C8 Z06 Problems".

OK - now have 330 miles. Sounds good cold but this when hot. Is this the dreaded Z06 ticking?

My suggestion, put more miles on it and have the Picoscan done. That will show graphic evidence of what your ears (and suspicion) can only guess at.

Preshenne

Good. Thanks for the recommendation. Will do.

Mine and a couple of others here sound like that. But mine is reversed, when it warms up it goes away, I don’t hear it when I’m driving and doesn’t affect the drivability. Everyone is different on their tolerance of what bothers them, it doesn’t bother me at all. I’d be more worried about a subpar dealer causing bigger issues than the mechanical noise of the LT6.

Thanks for the response. Interesting how its reversed!. I cannot hear the tapping while driving either. I note it when I stop and only with windows down or standing outside with it running. I am going to drive on and see what happens.

I do worry about a local small dealer tearing into it as a learning experience. However, I just had a C7 Z06 squawking pilot bearing replaced by same dealer. This repair was driveline disassembly from rear end to flywheel. They pulled it off without a hitch and the squawking is gone. So... maybe they have some skilled mechanics.

Very curious how the solid, non-adjustable valvetrain will hold up over time.

They claim at 100,000 miles it's still in spec. Time will tell, but with a 60,000 drivetrain warranty, they would be in a really bad place if all were shot by 50,000 miles.
