Did a boost leak test and noticed all the air from the test was coming out of the valve cover.
In addition the car idles fine, drives fine until boost. Seems to lean out and misfire terribly. When I say misfire, it feels like I'm entering boost and then all power is lost. Thing stutters hard all over itself like (who would've guessed) a huge boost leak!
Compression results yield about 120 psi on all 4. Service limit is 121 I believe so I know I'm cutting it close but at the same time I'm not burning oil and a drop of oil never helped my test so maybe my rings aren't bad. Engine has 155k on it.
This leads me to the head. I have yet to do a leakdown although I suspect guides and seals could be bad, guides in particular. Car Does not smoke. Also I plan on looking at mechanical timing of the 4g as it could have possibly slipped a couple teeth. Anyone experienced a slipped belt?
Any insight would be very helpful, may try new plugs and wires just to see as hopeless as it sounds. Something is not right, I Could log but no
CEL. I'm a confused.
