The stock factory engine uses a 'scroll seal' which is not really a seal at all but simply a technique to try to keep the oil from not getting out from a rotating surface. There is no maintenance possible on the stock set up as it actually is a metal to metal system with no replacable parts involved. As it wears the engine simply leaks!

Crank Rear Oil Seal Conversion 948cc/1098cc. This kit is for 948 and 1098cc Morris Minor engines only with the engine code beginning 9M, 10MA or 10ME. It will not fit 948 or 1098cc Midget or Sprite engines with the engine code beginning 9C or 10C. For 1098cc Midget/Sprite engines use part no. RIC778.

It will not work as a "bandaid" to completely eliminate oil leaks on a worn engine.

Question:
Will this kit might stop the rear seal leaking in my '61 MK1 midget? It has a 9C, (not the 9CG) 948 engine with a smooth case tranny in her now. Will the RIC775 kit work? Not sure what size the main is.
Answer:
All of the 948cc cars have a 1 3/4" main bearing size, so yes, this is the kit for your application.

Remove the flywheel, back plate, sump and the half-round cover, secured to the block by 3 bolts, above the main bearing cap (MBC). Carefully clean up the rear block face area adjacent to the MBC (Fig. 1 A); removing all traces of gasket, burrs, etc.; also the outer, horizontal edge of the flywheel mounting flange on the crank. This is where the new oil seal will seat; it will need to be checked for damage and carefully polished smooth with wire wool or fine emery.
