During my engine re-assembly I found an oil galley plug that was removed when 
the engine was cleaned. Not knowing this engine as well as others I have built, 
I do not know where to return it. I removed it from one end, and I believe that 
it resides right behind the cam gear, but I do not know which side, since there 
are 2 holes threaded there. Can anyone help me out please,
Colin
