On a dry test we got the following results:

Cyl 1: 160 psi
Cyl 2: 135-140 psi
Cyl 3: 140 psi
Cyl 4: 150-160 psi

On a wet test (dropping some oil into each bore/spark plug hole)

Cyl 1: 160 psi
Cyl 2: 145-150 psi
Cyl 3: 150 psi
Cyl 4: 160 psi

Car starts & drives fine no overheating, losing/mixing water etc...

The reason the test was done because it seems to give out blue'ish smoke now and then. When the spark plugs were removed for the test no. 4 plug was covered in Oil, is this normal?

Any input appreciated
