940 compression test
Hello, I have done compression test on my 940 2 LTR normally aspirated engine.
No 1 120 psi 2 to 4 150 psi Would you say this is acceptable? My tester gauge won't hold pressure, at first thought this might be an engine problem but, on reflection... I think it's the tester developed a fault. Any thoughts please? I will try it on another car. The reason for the test is... water coming from the header tank, (losing coolant.) missing till warmed up and, down on power, although, the 2ltr has never seemed that powerful. I'm suspecting head gasket on the way out. I does start ok BTW. Any input gratefully received.. Ken. |
