Reply To: Oil Slingers

[Mumbles]

The slinger is a press fit on the crank and it intercepts any fuel mix getting by the top crank bushing. It fits in a groove in the block and this groove has a small hole in it for the excess mix to get sucked back into the intake manifold area and burned in the normal way. If this hole is plugged, the mix might build up and appear to be leaking. Oil on top of the mag plate would indicate this. If the slingers fit is loose on the crank, it can be removed and deformed slightly to hold it in place or a bit of super glue could be used to. Of course the motor will have to be disassembled to do this though.
