I was doing donuts in a parking lot on a rainy day like a dumbass. anyways i pop the clutch and messed up. now i hear this loud banging noise that sounds like a piston slapping. when the rpms are low you cant hear but right when get on the gas it starts banging,

what does it sound like to you, and can you skip a tooth on your timing chain?? cause maybe my timing is way off,

thanks

What do you mean by a banging sound? Does it sound like a BANG? Or marbles rattling loudly, like knock?

Sounds like its your rod bearings or main bearings. Did you check your oil? If it's low that should solve your problem.

no its like a loud rattle, and it stops when its at low rpms, i think i just over reved it and i bend a valve and my piston is just slapping it.its not in my rods or crank, ive thrown two rods in two differnt cars before i know what that sounds like.

any of you guys know where i can find a used cynlinder head??

take the front of your motor off and check ALLLLLLLLLL your timing components because you might have a small... serious... couch.... (F*cked) timing chain guide just might be gone because they suck like that there cheap plastic so you'll have fun with that trust me
