Hi Forum,
As I'm sure my post will show I'm a forum nubie. We have a 1979 S2000. When we got it it was pretty rough. It would probably be easier to list the parts of the car that haven't been worked on. Rather than bore you I'll just say that the worst item was the small end of the number 1 con. rod. It spun the bushing. I pulled the engine and did a full rebuild. (My wife is the driver on this car.) I am very experienced mechanically, but this is my first Fiat. After the rebuild I have the car running very well, but the cam/tappet noise is very loud. I set everything to factory specifications, (which seem REALLY LOOSE to me),and the engine runs great but the tappets are really noisy. Is this typical? I have been building motorcycle race engines and they typically make very little tappet noise. They are also set up at fraction of the clearance called for on the Fiat. My manual says .018-.021 inches cold on the exhaust and .015-.018 inches on the intakes. Does everybody run those standard clearances? Any help would be great.
