Bluduh Engine problem

Today I had the center console engine cover off and I noticed there was oil on top of the hard black plastic CVT breather tube, I started looking at my crankcase breather hose and I notice about a 1/2 inch cut in it. Could this be the source of the oil? If so why does oil come back up the crankcase breather hose? I also saw no other areas that had oil leaks. I would greatly appreciate any help.

yes it could be the source.
Crankcase back pressure / overfilled oil / etc.. can be causes.

These motors create alot of crankcase pressure. Yes oil can come out and will. Alot of people run a siphon break to give the air a chance to go around the oil. $40 bucks. I use a PCV valve from napa and this helps by not letting the motor suck air in and making it worse. $1.99

Sorry no pics yet.. workin on it.
The PCV (positive crankcase pressure) valve is easy. Find a pcv valve that has the same size in/out as you current hose. Simply cut the hose somewhere between the motor and the air box or breather. Install the PCV valve a couple of hose clamps and your good.
