HELP!!!! OIL COMING OUT OF CRANK CASE AND OIL RESERVOIR VENT!!!

[Jacob Sawchuk]

So was riding along with the inlaws and all of a sudden smoke started coming from the front of the sled so immediately stopped to figure out wtf was going only to find out that there is oil puking out of my crank case and oil tank resivour. First thought was plugged vent line so took apart the vent line cleaned found a little bit of ice, so slapped it back together went for a ride the next day. Oil started puking out( my thought was that it was just the remaining oil in the line a used to flush the line the night before), so oil stopped puking out for about 2 hrs. Then got home again to see the fresh rage i put under the filter is covered in oil again!!!! Whats going on? Thought rings but the sled isnt burning oil when running exhaust doesnt have a blue haz to it norr does it smell like burning oil....

do a leak down 1st

A what

 

[blown apex]

a leak down is a tester that you use to put air into cylinder and measures% of ring leak
should be about 2%
4% and higher something is wrong with piston /rings/cylinder/rings/head gasket
maybe its not this but you wont waist time on other stuff if it is
if your boosted i would really do this 1st

Your are getting massive compression blowing by a piston / rings and pressurizing the crankcase and pushing oil out. You have a wounded motor...
