Perhaps, it could be a broken exhaust valve or intake valve inside your cylinder head? Not sure I could be wrong. If I am please correct me.

man i hope not, the tap isn't real loud can only hear by putting ur ear by the valve cover

what is your fpr set at??

BLK JDM

Do a compression check on the cylinders and see if they are in good shape. Also check all your vacuum lines and wiring harness. Are you throwing any CEL codes?? What ECU do you have in there. You're gonna basically run the same if you still are running that DX ECU.

i have the ex ecu and how do i do a compression check ?
my car throws a code when it's hot out an i beat it for some reason

BLK JDM

Check and see what the code is and to check your compression you need a tester and goes onto your spark plug w/ a pressure guage on the other end(In laymens terms). Crank the car but don't start it on every cylinder and the motor should have a consistent reading. If there is a 15% change in cylinder #s then you know you have something wrong in that cylinder where you're losing compression.
