    What is the all sizes of the spacer at the front of the crank for the oil seal to sit on? For m20 2.8

      Hi Roberts, I’ve added the crank spacer diagram to the gallery above (last image). It is sources from e30zone.net. I used to as the base but sorted out the final details when I turned the piece on the lathe.

      Thanks, Patrick 🙂

        Hi! Are you using stock piston on your M20B28 ??

          Hi – I used the stock M20B25 pistons from a 1988 model. They are short skirt type. If you use early model pistons the the skirts get in the way of the conrods.
