Hi I have recently done a compression test due to smoke out the exhaust, that i'm pretty sure is oil.
The smoke is a white/blue but I have an air-cooled 2.0 so its not coolant. The compression was between 130 and 150, 130 being the weakest cylinder #1 Compared to charts and other info this seems too high? Cylinder one also had the lovely surprise of an oily spark plug, so I'm looking for a leak but my compression is either ok or the test was flawed somehow, I did each cylinder twice. I also think the oil has been over filled by a mechanic (long story as to why i couldn't do it) so I'm thinking this might be a problem with the smoke but doubt it has messed up my compression readings? Any ideas?? Thanks

oil level to high can definitely cause smoking , drain the excess oil

Great, I was planning to do that next and give it another run out, I'll run a few times then redo the compression test, see if i get more reasonable numbers
Thanks
