Tonight I decided to check my compression on the 1985 Jetta Carat engine installed in my 1984 Westfalia. The engine was warm prior to the test and all spark plugs looked fine (slight brown) as they are 5000km old Bosch Platinums. All plugs were removed and the throttle held wide open. The engine was run for five "ka-thups" and the gauge was read. The measurements were: #1 - 170 #2 - 170 #3 - 190 #4 - 170 According to the Bentley Manual 145-189 PSI is what these engines should rear with the maximum difference of 44 PSI. I realize that I am not close to the 44 PSI difference limit, but why would one cylinder be way higher than the other three?
