MP cast covers, just got a new twist in breather so going to try that on a road trip tomorrow. Don't know what's worse oil soaked plugs or dirty oil after a few thousand miles? and yes I have the baffles in place and no my rings aren't bad and no my valve guides are not worn out. Yes carb is a bit rich. I am going to run breathers on both sides see what happens. May have been a bad PVC but it was free when I checked it and worked on vacuum so just experimenting now.
You can hold the hose upside down and drain oil out just a few drops and always seemed to be there wet all the time, seeing that go down the plenum just makes me sick. I know it causing the oil soaking. That and a lot of idling in the garage doesn't help.
So it should get fresh air in one side out the other, see what happens and report back, ran one breather on the drivers side and a oil cap on the other so only one air path in besides the carb lol and didn't notice a difference. my end up going back to the pvc, is the plastic one a good choice?
