Haven't split it but can wash it off run it for a while and all good, within maybe 30 min of shutting it off, starts to seep, after 2-3hrs starts to form a drip. Leave about a 30cm round oil mark on the ground overnight.

Hi fellas, Dads got a 237 motor with a 7220 behind it earmarked for restoration but has an oil leak. It looks more like engine oil than transmission fluid but only leaks when not running. All we can really see is it around the bell housing but wondering why it only leaks when not running? Im thinking rear seal and maybe when running there's pressure thats enuf to seal it. Also not sure how high the oil level sits in relation to rear crank seal. Any thoughts or suggestions on what to try/test before pulling it down? Thanks.

Yes, When looking at the filler plug the flat spot to the right/rear is where the model number is stamped.

There is a flat section on the left hand side to the rear of the filler pump where the ID number is stamped.

Dad put a 237 in his b model. It replaced the 711. Had to shift radiator fwd 20mm and kept the quad.
