I have lost a cam cover plug on a 1750 motor. I did not notice it was gone until oil was spraying onto the firewall! I presume that it went into the oil return galley at the back of the head. Will it go all the way to the oil pan? I can see into the passage all the way to the head gasket, and it is not there. It will fit through the opening of my old head gasket and I cannot find it anywhere else in the engine compartment, garage floor, etc. My question is, can I just get another plug and forget about the lost one, or must I remove the lost one as it may plug up the return galley. Any advice is greatly appreciated!!!
