Hi, I need your help ,
The car was underlining , starting badly and so on. In the car there were changed rings, gasket under the head. After measuring the pressures, almost every cylinder had a pressure of 90 PSI. I read more about this engine and found that the valve clearances had to be adjusted. I found on the Internet what the valve clearances needs to be. I measured the clearance and on intake it was from 0.05mm to 0.13mm which is very little, on the exhaust were from 0.15mm to 0.25mm. I thought the pressure was leaking because of poor valve clearance, as it was practically ajar while compression was happening. On the Internet I found the range and ideal valve clearance. I let the valve taps grind down and put everything back together. This time there is very little difference ... Cylinder 1 - 90PSI, Cylinder 2 and 3 - 100PSI, Cylinder 4 - 110PSI ... Normally, the engine should have a pressure of about 200 PSI (14-16 bar).


Any advice ?
