Yesterday I went out and picked up a compression tester because, just due to age, I expected there to be leakage. I did previously do a head gasket but the block is original and the head is untouched, and when I tested the compression each cylinder read out a solid 175 (156 minimum according to Bentley). After 22 years and over 249,000 miles and no compression loss, now that's German quality.

Hi MT,

Mind sharing exactly how you did your compression tests ? Just the best of three cranks or did you crank until you reached 175 and if so how many cranks did it take per cylinder? What was the variation across all the cylinders ? Thanks.
