I bought a decent, very original 230 sedan a couple weeks ago. Overall the car is in pretty good cosmetic condition but the engine needs help. The compression is below the minimum at around 100 to 115 pounds. It does run but it's pretty weak.
I've searched online but haven't been able to locate a source for parts to rebuild the lower half. Pistons, rings, bearings seem to be a rare commodity for this engine.
Is there a source I've missed or are the parts just difficult to come by?
