any ideas? cuz i'm out of them.

i have a noise coming out of cyl 3 when motor is running. proportionate to engine rpm. i thought it was valve prob like a lifter or a rocker, so i ended up pulling rockerArmStopper(s) off to no avail. rocker looks good, shims in place, and lifter doesn't seem dead...

here is the odd part. noise goes away when i pull #3 coil... i gotta pull a compression test next time i get a chance, but car is in storage and only have a couple hours a week to work on it so i was trying to put together a list and prioritize my attack.

tidbits to know.

car was sitting for about 2 years having run about 1 tank of gas in those 2 years.

car was running well before noise came out last time i took it out.

car idles perfectly

car isn't really spitting smoke(other than being slightly rich and a little oil from old t3/t4)

power is ok, except i think it was a little weak when i took it out last, but it was smoothe.

ti retainers, tomei cams, new valves, tomei springs, took out the RAS. s13 sr20.

any ideas other than a religious rotating asym?

thanks for help
cheers

sounds like low compression, or rod knock
