So I've had my car for three months now and still cannot figure out what this noise is! I'm by no means a mechanic but have common sense around cars, celicas inparticular. It's a mostly stock 7a-fe with 194k and 5 spd tranny. The car runs fine, and since I've had her changed the oil, spark plugs/wires, exhaust manifold/down pipe(original was cracked), and have had no other problems...not even a check engine light. I can't find anything loose that would rattle, but there is a significant power steering fluid leak.
http://youtu.be/FOrH0HC7l5w Please see the video I put on youtube to hear the noise, which is most notable on a cold start and anytime I'm constantly holding revs over 2500rpms, but will stop if I floor the gas or let off it completely...It's very annoying on the freeway(but isn't noticable with the radio on! ha!). I'm thinking maybe a bad piston ring, or possibly something in the fuel injectors??? I should also say the noise does seem to emit from the passanger side of the engine bay. I'm worried it may be time for a rebuild as I do not know how the previous owners treated her.  If that is the case my biggest challenge would be finding someone I trust to do the work, but I'm sure you guys can help point me in the right direction for that!  -------------------- 2004 Celica GT-2zz w/6-speed swap

Well, if you're ready to swap soon go ahead and keep driving it until it pops.

Well I wouldn't say I'm "ready" for a swap, but I have found a company that I can buy an engine block that's already rebuilt or I was thinking I could find another used 7a-fe to rebuild or swap in... not really sure which way is most cost effective. I've only had the car for 4 months, but have no idea how long it was knocking before I got it. It runs great, so I'm sorta in the "if it isn't broke don't fix it" mode as of now. Plus if I can put off dropping 1500-2000 dollars into it right now that would be nice... -------------------- 2004 Celica GT-2zz w/6-speed swap
