Mayonnaise V11EV
« on: October 03, 2022, 10:16:39 PM »
So no matter what I do I get some water homogenized into the engine oil. The bike gets run on long highway hauls on hot days and I still find some mayo in the bottom of the pan. I'm assuming the practice of cycling oil vapor through the top frame tube is to blame. Season doesn't seem to matter. 400 miles down the highway on an 80 degree day doesn't eliminate it. No oil cooler or deep pan installed so the oil is as hot as it's going to get.

How can I make this contamination stop.

The moisture needs to be vented out with the crankcase pressure.

I would check the venting.

I've blown 120# compressed air through the whole system last time the engine was out. The check valve at the crankcase discharge pipe is new so it's not sticking.

Might be worth by passing the frame tube and fitting a catch bottle instead.

If you think pushing 60 is bad, wait 'til you have to start dragging it.

I really dislike frame tubes as breathers...I bet there's tons of nasty stuff in there.
