[SR2oD3T]

long story short, went to drifting event 2 weeks ago and drifted pretty hard. car spung out couple of times and engine stall. realizing a little lack of power, weak start up, but still pulls when turbo kicks in. drove home fine just feeling a 30% power lose. did compression test, 100psi on all four. (was done when engine is cool and forgot to WOT, but i shouldn't be that low). did some research and i m pretty sure the timing was jump that causes losing compression on all 4 cylinder and have same reading.

did some research, #1 cylinder at TDC by looking at the crank pulley, both in and ex cam line up with the dots on the sprockets and the silver mark on the chain.

question:
i m thinking it might jump a tooth in the crank sprocket. even tho the cam sprockets all lines up, i have no way to find out if the crank is line up with the chain unless i drop the oil pan, take off the oil bump and all those right?

from research, the two silver spots on the chain is just for initial installation. once the engine turns, it takes up to 60 turns at the crank before it lines up with the dots on both cam sprockets.

going out for dinner now and i think i can't escape from taking all those things apart. just wanna get more opinion from u guys see if i m going the right direction.

btw, its a s15 sr20det.


thanks
