I did a compression test today to see how close compression is between all 8 cylinders. The readings were: 175 - 174 - 165 - 175 - 175 - 180 - 180 - 210

The 165 and 210, giving the greatest differance, 45lbs. this is not a good thing, but I will have to live with it! It does run and perform OK!

What is the spec for compression here? With only one cylinder well above the rest at 210, I could assume that all cylinders were once as high, or higher but dont know for sure?
