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

All you are doing is wearing the already worn pieces more. Instead of taking off .005 now they have to take off .010, no big deal. That my .02 |

I figured it would be toast if I did, but I've never had this problem before. -------------------- 2004 Celica GT-2zz w/6-speed swap
