First things first ive done a compression test and all four cylinders were 160psi bang on witch ive been told pretty much rules out the piston ring's! My car is burning a small amount of oil witch I believe to be my valve seals and ive got it booked in with TD to sort that out! But with my oil cap off it smokes can this be the issue with valve seals or piston related? Also my breather smokes intermittently, I'm just concerned about it being more than im expecting as I don't really have a spare 2k at the moment!
