hey.. having a lil problem.. i think it could be my clutch but heres the situation

went to the track yesterday... ran 11 runs... stock clutch... exhaust came a bit loose so i tightened it up the next day.. didnt notice anything... now i hear this rattle... it happens right after i start going or switch gears and at about 3000rpm... it sounds almost like an exhaust bolt is rattling but i checked all the bolts everywhere and couldnt find anything.. ehh dunno its kinda odd.. i wish i had a video camera to record the sound

 

forgot.. clutch doesnt feel different.. doesnt slip or anything so i dunno what it could be

car is a 95 coupe and the engine is a 94 b18b that i got a few months ago

if i put it in neutral and rev it it wont do it.. its only when im putting load on the car

 

did you check your heat shields, especially the one on your cat convertor? they like to loosen up and rattle under load.

 

no cat.. adn i did check the one under my shifter in that area.. but ill check over everyhting again.. thx.... anyone else?

 

Not much we can do to help without getting under your car. Check suspension, brake lines, heat shields, swaybars and engine mounts.

 

i checked over everything.. even stuck a piece of cardboard in any loose heat shield.. sounds like a bolt rattling... ahh i need to find this

 

well I had the same problem, it was a part rusted off my exhaust just chillin hanging on the pipe moving up and down, it was so annoying and embarassing sounding, I still haven't taken the torch under there to cut it off, it was a sort of cuff over the resinator, it was like a circle thing like the end of the resinator where they tac the cylinder to

 

perhaps the hangers from the muffler are resting on the bumper support? that happened to me before i cut and shortened my cat converter?

 

its not the resonator bc i dont have one.. and its comming from the front right near the transmission so its not the hangers on the bumper.. thanks though

 

do you run a cold air intake? sometimes where they pass through the front fender area they will touch the metal at times under load and give you an annoying vibration. Mine had a rubber collar that would move out of place just enough for the pipe to touch the frame and it took me a while to find the noise. I got rid of the collar and used rubber hosing around that area and haven't had any trouble since. Other than that I would check your lower front P side tranny mount from under the car to see how it looks.

 

i figured it out... one of my exhaust bolts was rattling.. and the reason it was doing it only under load was that the engine would move ever so slightly so the exhaust would be somewhat compressed and the screw would have enough room too rattle.. but when the enigne wasnt under load it didnt move so the screw was actually being pulled by the exhaust... ehh stupid things like that
