O.k. I have had the turbo s checked out. Leak down cylinder 1=3% drop, 2cylinder = 2% drop, 3 cylinder= 3% drop, 4 cylinder=3% drop. Compression #1= 145lbs, #2=145lbs, #3=140lbs, #4=140lbs. Two leaks 1 at pressure relief valve at oil filter. 2 at back of cam housing. Round gasket with tabs. Both are minor. Finally the boost tops out at 1.1 at 3700 rpm. This seems low. What do you guys think about this data?
