I think I have this issue as, I thought it would've been one of the belts. It was like a knocking/ticking sound. I haven't had a value adjustment or TCT replaced so once I get that done, I'll report back here.

It just sounds like it, I dont think its rodknock if everything was replaced, but it has to be knocking/tapping from somewhere..

I would just start pushing on different parts of the car in that area to see if I could change the sound or make it go away. I have scared myself plenty of times on the S and other cars and found out it was just a body panel rattle or something. My 240sx was notorious. Just about every time I got home after late night spirited driving there was some knock or rattle that turned out to be a body panel.

Posting for interest as I think I have some sort of noise as well

'02 Ap1 with 37k miles, but I'm beyond paranoid. My previous car an '02 Celica spun a bearing so any knock or rattle sets my imagination wild.
