I have a similar problem. I have a knocking sound coming from the intake cam (cam on drivers side). I've done the stethoscope test and narrowed it down to the drivers side cam housing but its sounds like its not the block. The knocking only happens when the car is in gear and trying to move. At the same time, the car is leaking oil down onto the exhaust pipes. I think I've narrowed the oil leak to the head gasket.
Just to be clear, I've owned this car for a few weeks. I have very little experience working on cars. So if I given the wrong name to a part I hope you'll overlook it. When I took the car in as trade it was idling rough but it was drivable and I did not notice the knocking sound or the oil leak.
I would greatly appreciate it if you would point me in the right direction. I have not been able to find a mechanic in the Kansas City are who knows these cars so if anyone can refer me to someone that would be great.
I guess it would help to know my car is an 80 2000 Paranna Farinna (sp

) Spider. It is FI with a 5 speed tranny and has 55k miles.
Thanks,
Rob
