Well I fired up my new built C16SE tonight I’m running twin 40s.
Started up after 5 turns beautifully,went for a drive 7 miles in starts missing/smoking out of exhaust and oil out of the cam cover breather,removed all 4 plugs to find number 4 oily,I’m thinking blow by what are your thoughts?? Can’t find my compression tester,what compression should I be looking for roughly? Can’t see it been a hole in piston from running lean.
It was smooth,no smoke and no nasty noises just suddenly smoke then missing
