Right, i got down and dirty today
Took all the plugs, done a compression test on all cylinders, it was 150 psi give or take 1-2 psi on each cylinder
So the rings are ok
took the pipes off the turbo, no play on the propeller, also started it up still disconnected from the IC reved it hard, and on boost, a light mist of oil came out.
Am i right in thinking i have nothing to worry about?
The smoke my mate saw was just some on my gear change (Going through the gears hard and fast)
