Should oil be coming out of my crankcase pressure releif hose after running in 4th-6th gear for awhile?

i have a 06 Yamaha Blaster and after i get done riding it in 4th-6th gear full throttle for a while i will stop to let it cool down, but when i do i notice that it has oil coming from the crankcase relief hose and i dont know if it is suposed to be doing that. i did try and plug it and the piging noise i have in the head went away but when i removed the hose i had a lot of pressure in the crank. so i was woundering if there is a way to keep the oil in the crankcase but let the air out.


OH YEA i just bought this bike 2 weeks ago and its my first 2 stroke so i dont know alot about 2 strokes.Should oil be coming out of my crankcase pressure releif hose after running in 4th-6th gear for awhile?
Oil is never suppose to come OUT of anywhere on the engine.





Something is wrong with your Blaster.

Remove the oil fill cap - does it smell like there is gas in the crankcase?


If so, the crank seal could be leaking - pressure from the engine could be blowing into the crankcase.
the blaster is a 2 stroke engine


the crankcase is sealed from the rest of the engine


you use oil in the engine for the transmission gears and the clutch


are you sure the oil level isn't over filled?
