Knights of the SOHV...Heed my call,
What's up, sailors? I've been out of the game for a while, but I'm back. Way back in November I had some issues with oil not getting to my cam shaft. I was able to blow it out. But I'm going to build the engine just to be safe. However, something that has been plaguing me is white smoke out the breather tube. When I first got the bike the rings were worn, I replaced them & rebuilt the engine. She ran perfect, minus the smoke out the tube. Then my bolts holding the Cam sprocket sheered off...(never forget to use a solvent on those bad boys). So I'm about to do another rebuild and I'm trying to avoid the breather tube smoke again.
Any ideas what could be causing it? I put too many miles & road it too hard to be residual in the top of the engine after the rebuilds. I'm thinking maybe blow by in the rings? The compression tests were always spot on. I inspected the rings & they looked perfect. I honed the inside of the cylinders each time. Would oversized rings be a solution?
My engine oil level was always within spec. An old timer told me not too long ago to keep it at the half way point that the high oil mark was too high & caused too much oil up in the fly wheel. (I think he just liked to talk though)
I want to be clear, this was't soft gentle puffs of smoke, when I was at a stop light or stop sign, I would notice the smoke bellowing up around me as if Santan were ready to pull me into the depths of hell.
Anyway boys, its good to be back. Thanks in advance for the help.
