I just got the motor back together with APR Head studs and Cometic Gaskets and everything in my signature below… Car runs flawless, no miss, no leaks, no water in oil ect.. Runs nice and cool (167-175) and I have always run a mix of 110 or better..
Anyway under WOT over 20lbs of boost I hear what would normally would sound like the compression blowing out the side of block.. IE head gasket… I get absolutely no KNOCK associated with this noise and the car does not seem to be down on power at all…
I tried to re-torque the heads and every thing was nice and tight.. Plugs look great, and there is no evidence of any carbon blow-out anywhere between the gasket and head/block. I don’t recall hearing the noise at the track, but it may have been because of my helmet?? But I also feel it is a new thing..
This set up has less than 500 miles, only 1 trip to the track, and I am just not too motivated to tear it down again, I tried to spare no expense and I am not real happy at this point. If the car fell on its face when this was happening I would feel more inclined to take it apart.. Like I said the car (as of now) Runs Perfect Up to 26# of boost and no knock…. But with this (farting, subdued popping/knocking) noise is the best way I can describe it. And appears to be coming from the drivers side..
Any other possible areas to check or ideals for what this noise may be..
Thanks,
