I found the major oil leak but do not know what this thing is; It is a plug that is at the rear of the right cam/head . When I took off the bracket that holds it in place I just pulled it out with my fingers and it was covering the end of the overhead cam shaft. It has an "O" ring around it that was pretty flat but on further discovery it was like a plastic or fiber material and broke. I put it back on this plug and used some high temp form a gasket and shoved the plug back into the rear of the head. Replaced the braket and the leak has stopped. Is that plug simply a hole to remove the camshaft if it needs to be worked on?
I still have a minor link around the rear bearing of the crankshft but not that bad. This plug thing on the rear of the camshaft was the main one.
