I am doing up a mates 1971 T120 engine, I have found the previous owner had fitted a primary seal on the crank, I understand this should be deleted on 1970 and up? The engine had a top end overhaul, and unfortunately the DS piston picked up and partially seized. Can any one advise if the restriction to crankcase breathing could have attributed to the piston smearing itself on the bore? The only place I could see the engine breathing was through the oil level holes between primary and crankcase, and they are pretty small.
