ZR-1 Engine Noises
Morning all,
I went to look at a 1990 Z yesterday and noticed that the engine wasn't as smooth as I expected it to be and the motor had what sounded like a top end rattle when you stabbed the gas and it returned to idle. I was under the impression these were super smooth engines. Car seemed to have plenty of power.
Any insight?
Tony

If you are seriously considering buying this car, I'd be happy to come and do a full inspection of the car for you
It likely needs basic maintenance (injectors / plugs / wires / pumps).
Shoot me a pm and I'd be glad to discuss the car

I am not sure what pumps we are talking about? Vacuum leaks and vacuum pump high rate of cycling I know which is sometimes normal for a vacuum system 20 years old and not maintained (an easy fix).

If the car has a miss,not running on all cylinders the cam chains-flywheel will rattle,sounds like a mild rod knock.The injectors go out in these early cars,not a question of if but when.

Thanks for the replies guys I appreciate it and a big Thank You to David for the offer to inspect it. It looks like the car has sold anyway. It was priced right at 11,500, but more than I wanted to tackle honestly. I'd rather spend a little more money and get something that's ready to go.
David, if I find something the peaks my interest I will contact you
