As you will hear from this video, my car has this very strange knock, wich has been described by many people as being identical to the sound of a Volkswagen TDI motor. The thing is, it will be knocking away one minute, and then just randomly stop and be completely quiet for a while. The performance does not seem to be affected at all. BTW- It's a 97 GT 2.4l 5 speed, 80,000 miles

Ouch, thats pretty sharp. Sounds like valvetrain noise to me... I'm not really sure what. Weird that it would be that rough at still go completely quiet at times.

I'll probably have my mechanic take a look at it some time today. It's really annoying. Also, notice how the engine almost dies after i rev it up the first time, could this have something to do with it? That happens any time I rev it up.
