I am getting an oil leak that seems to be in the front of the engine, low down. What are the likely sources of the leak. Thanks - Scott

These type of plugs are a possible source of a leak because they are not threaded plugs. These plugs will present some oil leakage directly above the front cross member. At the other end of the oil galley, they can also cause some oil leakage at inside the bell housing. Joe

There could be some leakage of oil there, but if your getting oil and water, I'd say the head gasket may be leaking at the rear of the head and that oil and water could be running down the back of the block into the fly wheel cover.
