For the past month I have been getting blue smoke under boost and idle so I finally got some time off to take a look. After getting 150 across all four cylinders during the compression test I decided its time for a leakdown. During the leak down cylinders 1,2,4 all checked out only 2% psi drop..But when I to 3 is when I started to wonder it was. When I added pressure to 3 it came out of 1?! What does that mean?
