Peugeot XD 2 motor front main bearing seal.

Checking harmonic damper and replacing front main oil seal . I had done some maths of the compression ratios on the motors with different piston protrusion height and bore sizes. When standard the compression ratio is 22,2 : 1 . With the resleeved over size 94,60 mm or 0,030 '' and 1mm piston head protruding into cylinder head gasket space , the compression ratio is now + - 24,7 : 1. The cylinder block was not resleeved but is rebored to 95 mm or 0,040 '' .The piston protrudes of the less resufest motor block is 0,98 mm into the gasket space and has now a compression ratio of + - 24,8 : 1.

What is the socket size on harmonic balancer? Great video BTW

Hi , I think it's a 22 mm socket. Thank you.
