Re: (cviccoupe)
Rod knocks have a relatively deep, hollow tone to them. Is it like that or is it more of a clacking metallic sound?
You could always put the car on jackstands and have a buddy rev the engine while you listen to the oil pan. If it's a rod knock, you'll know.

Re: (Kobal)
yea it starts at around 3,000 rmp and sounds kinda like a rod knock,i pulled each spark plug wire otu one at a time and still the same thing a went under the car and started it and it does make that noise around there..it really weird like i said ...in the hayens manual its says that it could be from not the right octane or old gas....when i boughtthe car it had a 3/4 a tank full but has been sittin for over a year because of a bad tranny.so i bought it and put a tranny in it and i never heard the sound then i let it sit for a month while i did body work on it and changed the oil with the cheapest oil in it from advance auto then i noticed the noise...
