My pinto is making a tapping noise, it goes away nearly completely once it warms up. I dont know if its the lifter cam or what. Someone told me it sounds like a wrist pin to him (he wanted to buy my car and may have just been trying to scare me).

 I made some recordings so you can hear it running, and uploaded them. I hope Im not breaking any rules, this hosting site seems ok to me I made sure it was safe. You just have to go the url and then hit download filer and the captcha thing.

 If anyone can tell me if they ever heard this noise or if its possible to get an idea what it is from t he  sound on the recording. I was thinking about trying a software analyzer to see if I can get a look at it if that could show its a wrist pin or not. I heard theyre like a double tapping from when the piston goes up and starts to go down.

 Its a 2.3 with about 30,000 I guess, since it was rebuilt. The noise goes nearly completely away once it warms up did yours do that too? It is worse when its colder outside and goes away, so maybe its an exhaust leak even. How much do you think someone will charge to take the rocker cover off and look at it? Most of these places try to charge sky high and act as if working on an old car is harder. I always try to have some idea before I call around.

 sorry if I confused anyone it was rebuilt about 30,000 miles ago. Thats more than a few years now since I dont put 5 or 6,000 a year on it. I had other cars over the tears too, but this one stayed with me.

 I dont think the valves are adjustable but I can try that lucas treatment, I heard a few people say good things about Lucas. It gets good mpg though and seems to run fine other that that noise. Would a stuck valve get quiter after it warms up, and not cause more obvious issues?
