I have a 1999 Toyota Camry LE with a 2.2L DOHC engine. I have what seems to be knocking in the valvetrain. It will make noise sometimes after a cold start, but I put Slick 50 in the engine and it has helped that noise. It doesn't make any noise while idling, but as soon as the engine reaches 2000+ RPM, it sounds like it's knocking in the top end of the engine. What could this be, and what can I do to repair it?
have the same problem?
