After I start the car it sounds fine...for about 30-45 seconds..
after that a 'knock' is heard bewteen 1500-2000 rpm. Above 2000 rpm there is no noise.
In the last few startups the knock has gotten progressively louder.
I tired using a stethoscope to locate the noise..but it seemed to be coming from the valvetrain..
however It seems loudest right behind the header. (could be echoing)..
I drained the oil and filled new oil..which seemed to make the noise worse..
I checked the oil and filter for metal particles (with a magnet) and it had none.
Any suggestions?
I'm ready to just order another h22 and swap it in already.. <_<
