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?
