I have two breathers, per side. I run plastic pot scrubbers in each of the breather tubes, to help the
oil vapors condense before dribbling out of the breather caps. Was working pretty well, but I'm thinking that my 35K miles of running just screens on the Webers has given me some ring failure and I have bypass pressure blowing
oil out of practically all the gasket surfaces. Not really wanting to do a re-ring job, this year, I'm looking for another fix. Will exhaust scavenging work to pull pressure out of the crankcase or would it actually add more pressure?
