Thanks but it is a bit too far for me. Compression low in cylinder 2. Looking on here there seems to be some good feedback for swift in Westerhope so i think I’ll ask them to do a diagnostic and go from there. It’s still running on 4 but oil light came on, I tooped up right amount but it then billowed blue grey from the exhaust. Once that is over it settles down and runs fine but expectation is piston ring or ocr?
