Recently went to a drift event with my car. Car ran great most the day, engine has always had an intermittent knock/head noise. anyways
s14 sr20, 9:1 compression (unknown pistons ) 2871, and basic upgrades with a apexi power FC commander.
I pulled off the track because i heard a nasty knocking from what sounded like the head, I idled off the track and there wasn't much of a noise at idle, but when i gave it any gas above 1200rpm it would make a nasty knock/ slapping noise. Kinda figured it was a rocker, but I inspected them now that it's home and there are no visible issues. No chunks of metal in the oil either. When i would rev it up, the power FC would show knock, It ran for maybe 30 seconds all together once I noticed the noise.
Any insight? I plan on taking the intake off tomorrow and looking inside a little better.
