November 2019 Forum Retirement
Due to lack of extra personal time (and too much spam), I'm retiring the forum and setting it to a read-only state. No new registrations or posts will be accepted as of 11/09/19. However, all information will stay up and searchable. If you spend a few minutes searching, you'll find the answers you're looking for. We may re-open the forum next spring.

I was going to swap my stock air filter for a new one and found about 2 tablespoons of oil and or gear oil in the air box, this doesn't seem to be normal. Plus my oil is only half way up the dipstick. I'm kind of concerned as my trailmaster only has 160 miles on it.

Oil accumulating in the stock airbox is normal, but happens in larger quantity when the crankcase is overfilled.

The intent by the manufacturer of routing the vent to the intake, is so that aerated oil from the crankcase vent will get sucked into the engine's combustion chamber and burned.

I hope you got a UNI Filter instead of new stock airbox.

Thank you for the info. I plan on purchasing a Uni next month along with a few other upgrades. Does the Uni have a place for those 2 vacuum lines?

It doesn't. With the UNI installed, you allow the two vent lines to hang freely unconnected. Keep in mind that positive pressure comes out of these vents, not vacuum or suction. There isn't any risk of dust entering the engine.
