Rear of Engine Gaskets & Seals
Up until 1979 the oil in the sump was retained by a thrower around the front and rear of the crankshaft. These throwers typically become "sludged" up allowing oil to bypass the thrower. On the later B Series engines (from VIN 39628 approx) an oil seal was fitted to the front and rear crank covers.
We have developed a kit UE7488KIT that allows the later type seal to be fitted to earlier engines.
