Engine noise and oil leak Car's a 2000 Z28 with almost 90k miles.
About 500 miles ago, I had my knock sensors replaced. The SES light is still on. When the guy pulled off the manifold, he dumped out probably 6-8 oz. of oil. I figured that was from a bad pcv valve, got that fixed. The engine leaks oil underneath but I cannot find a visible leak.
Also, recently the engine sounds like it has a bad vaccuum leak but I have checked all the hoses and tightened everything, still sounds like something has a hole in it. It is very noticeable, especially in the garage.
The worst part... the car is starting to idle really roughly and at very low throttle, I hear a clicking sound-if an engine could fart-this is the sound it would make--almost a gurgle. Throttle response is nearly 0 at 50mph...
I have changed the plug recently as well as the oil. I have also seafoamed it, changed the fuel filter, the pcv valve, and I thought I'd ask before I went and spent a fortune I don't have at the dealer.
Thanks in advance.
