my 91gsx has, from pass to driver side cylinder compression results 88,150,88,150. when I bought the car the valvecover bolts were loose not even tightened oil was leaking at the vc gasket, the car also came with 16g and manual boost valve. the car had no power it just drove as a nonturbo, I thought turbo was bad so I tried to check it out and when I detached the heathers there was a metal peace stuck inside the exhaust side of the turbo preventing turbo from working properly. I use this car as my daily comuter but I like it its awd so I'm trying to fix this compression problem, i'm trying to learn what should I expect with these compression results. I drove the car for a long time about a year I havent noticed any out of ordinary oil lacking when changing oil I take it as the car didn't burn oil. usually when changing oil there is always a bit less of old oil due to it's quality or whatever. the car does not smoke and runs just fine, there is also a clicking on passanger side of the engine at the very corner to the front of the car, so the corner closest to the front head light on the passanger side, other then that the car runs smooth. also at one day while driving I was at red light and at green i gassed it (when this happened I actually felt as if something sealed right and it now had the power) first 2nd 3rd gear and the car lost the power at the 4th gear and continued driving as it did before like a regular nonturbo car, though when I took off at light there was a giant black cloud behind, something that I never seen before nor again only at that time. I'm planing to do a valve job on this car so I wanted to see what are the possible parts that might be at failing with such compression results, and what might be of further use, I drive this car everyday so I'm not trying to make no batmobil or nothing like that, just fix it to work right. I appreciate any help and sorry about long ltr.
