Right now i am getting no boost at all and no idle surge. I have tried searching and searching, but have had no luck. I have 20' on the vacuum gauge at idle. The car has been sitting for some months because I had high oil pressure problem. Fixed that and now it cranks and runs smooth but no boost at all. I tried a boost leak test at the throttle and turbo and it still leaks at the same spot. I can hear air rushing around the bottom left part of the valve cover. Pulled it off to see if i could see something wrong with the valve stem seal, but I couldn't see anything I have already tried cleaning the EGR and replacing the PCV because i read that those might leak too. I did a compression test and from left to right its 150, 145, 140,140. I see that its getting close to needing a rebuild. The turbo spins freely and i looked at the blades and don't have any damage to them. Does anyone have any suggestions on where to look next or recheck?? On the boost test i cannot build any pressure at all no matter where i turn the engine too. Thanks
