Hello all, I measured the compression on my v70 times to finally find out why the so much oil consumes (in the meantime >1L/100km). I measured 13-13.1 bar on 4 cylinders. Only the second cylinder has only 11,7 (11,9) bar. I measured again after I had put a little oil in the combustion chamber and then the measured values went up to 17 bar, equally on cylinder 2 and the other. According to the Haynes is probably 13bar just ok. Therefore I hope, that the cylinder trajectories/pistons are still OK and it is due to the valves/valve shaft seals or to the PCV system. It is the 2.4L 10 valve suction cup. Has anyone ever done the compression on this engine here and can my measurements be classified and interpreted in more detail? VG Jan
