Default pistons hitting my head....no not that one!

hey all
got badddd news (well bad for me)
all cylinders are firing but sounds like a piston is hitting the head
spun bearing i think (no...10psi on a non intercooled stock d16 may be the prob...lol).
what do i do next?
should i take the oil pan off and look?
what do i look for?

if the bearing is spun lol the rod should be going threw the block when boosting.
Do you hear the spun bearing noise??

that ticking is your rod spinning around the crank

you boost it much its likely to become a permenant fixture int he side of your block; dont boost it you ------- idiot.

drop the pan; check it out; pull the motor and do a full on rebuild; you'll need to turn the crank or buy another one (whichever's cheaper) pick up a new/used rod and probably pistons since you more than likely grenaded the ringlands with 10psi and no intercooler and i seriously doubt its very well tuned so yeah....

your motor is fucked...

It is the way you're asking your questions that promote these "attitude" toward you.
Nobody will hand you a built bottem end.
There is no way you can tell what's going on without tearing up the motor.
And stop the exessive use of the Return key.

if its really the rod knokcing against the crank it wont last very long. mine lasted 3 days after it started... if you keep the revs low it'll last longer
