My 87 Westy has a 2.1 WBX with about 130K miles on it. What does it
mean when the coolant/oil mixture drips from where the the two
crankcase halves meet? I am absolutely sure that the leak is not where
the head gaskets are. I did the head gaskets in the last two years,
and even upon close inspection the areas around the head gaskets are
dry.

Also, the compression on the rear driver's side cylinder is low (7.5
bar) while other three are around 10 bar. What to do next?
