    I have a running engine is 351 cleveland and i have done compressor test to see how it is on the rings because it burn oils. The compressor for this 351 engine is around 140-190 psi right and my engine first clyinder is 175 , 2nd 200, 3rd 175, 4th 175, 5th 180, 6th 180, 7th 175, 8th 170 psi. Why is 2nd clyinder 200 psi and 8th cly 170 ?

    Sounds like #2 cyl is sucking oil sealing rings…did you ck #2 cyl more than once ..It’s possible that the valley pan(intake gasket) is leaking and sucking in oil at # 2 cyl
