I toped  off the engine oil the other day and slightly over filled it  
(65  110).  I later discovered that the extra oil had found its way   
into the right muffler and made much smoke out of the pipe as it   
burned off.  My question is: how did the oil get inside the  right  
exhaust pipe and muffler?



John, I really doubt that this is your problem. First, slightly over  
filling the oil sump will not cause that type of problem at all. Also, are you  
sure that the oil has accumulated in the muffler? If it is in the muffler, it 
 must have come there while the engine was running and oil seeped by the 
rings,  or some other way. Remember, if oil is in the muffler, it will take 
quite a  period of running to heat the muffler enough to vaporize the oil. 
More likely  what is happening is a coincident occurrence of the cylinders 
cooling to an  out-of-round condition and the oil passing by the rings upon 
initial cold start  up.
Please comment.
