The easy answer to what I'm asking is "do a compression check dummy!". I will, tomorrow but maybe this is normal. I have intermittent power, when i apply the throttle the car boosts well, then 30 miles into my drive i would hear a rushing of air noise and loss of power when under boost. It still has power just not the push me into the seat kinda power. So i have been pulling over and tightening and adjusting hose clamps and have been able to get the POWER back, but then sooner or later Its the rush of air again. The real problem here is im wondering if my rings are bad: To fix my leaking pipes once and for all I sealed the intake part of the turbo and applied some compressed air and watched my boost gauge, i got it up to 8-9 psi and my dipstick popped up and air rushed out. Is that normal? I could watch the boost gauge dive when the air rushed out my dipstick tube. That would have to be my rings? Thanks for any help anyone can be, im not too enthusiastic about the idea of tearing this beach down and throwing in new rings, ...
