hello,
First time being in a forum so please be patient, I'll do my best to keep this short.
1991 acura nsx 149k supercharged
(don't know if that needs to be said)
Had the car for a couple of years and never had an issue with it, I took the car to the track. First lap was fine, second lap 3 gear at 8000 rpm, biggest black cloud of smoke I seen in a car, car shuts off, I get off the road, I can't see shit because the whole Rear window is covered with oil, when I go check, a part of the valve cover gasket is hanging out, crazy spill of oil everywhere, I towed the car home, when I get home. I start to take everything apart, I have oil in the intake manifold, I have oil, running through the sideskirt, I remove the valve cover, it was the one toward the rear end of the car, I replace the gasket, turned the car on.
Car is running fine, no problem, when I drive the car at low rpm, everything seems fine, if I pass 6000 rpm black smoke will come from the exhaust, only from.the left side, and I have a little oil leak somewhere that I haven't been able to find, it sits on the headers, but it's little, All this happened 2 years ago, i was away and couldn't get into it, when I came back home, I Been using the car like twice a month, not passing 65 MPH and shifting below 4500 rpm, the car doesn't feel like it has lost power, a couple mechanics have checked the car out, but there's a lot of theories, pvc valve, blown piston, bad piston rings, one told me I need to buy a whole engine, one of them said the car just need to be tuned, another said it was the head gasket. So question is (sorry for the whole story) does anyone have a clue? On what is going on? I just don't Want to bring the car to a shop and get charged an arm, if there is a way I can figure this out myself.
Hope this makes sense. Thanks.
