Breather-1,2, or none?
			 
			 
			
		
		
		
			
			My 62 has 2 breathers, not the same. Smoke comes out of the passenger side at idle and apparently at hwy speeds since I can smell it when I run the heater fan. I replaced the passenger side with a cap from one of my parts motors. This seemed to help. 
 
 I looked at all 3 motors and they were all configured differently... 
 
 The 62 has the replaceable filter behind the drivers side cylinder head with 2 breathers. 
 
One of the parts motors has the filter, one breather, and a cap. 
 
The 3rd motor is a 66. It doesn't have the filter behind the head, just a solid unit with a pipe that goes to the air cleaner. It has no breather, just a cap on the passenger side valve cover and no hole at all on the driver side. 
 
On my 62 I put caps on both sides to see if it ran any different and it doesn't but one of them doesn't seal so not a conclusive test. 
 
What is correct for this engine? I was thinking the rear filter assembly might not draw properly with breathers in the valve covers? 
 
I still haven't finished cleaning/painting parts to swap out with the filthy stuff on it so I could still use the one with no hole stamped in it if a breather isn't needed.
