oil pushing out of valve cover breather tube

[rlstoug]

could use a little help. working on a friends spiderbox. it has the howhit gy6 and it runs great. the problem is it pushes oil out the breather tube and apparently the force is great enough it even pushes the fitting on the valve cover right out. I have 3 other buggies with the gy6 in them and I've never seen this happen to any of them. any help would be greatly appreciated. thankyou

it isnt overfilled with oil is it?

[rlstoug]

no, it is actually a little under the fill line right now.

perhaps the hose is collapsing in on you and
then it blows the fitting out.

May have something going on with the valves. Check the valve adjustments.

Or put a new hose on there and see.

The piston rings could be worn out causing extra crank case pressure.

took hose off and still had the problem. I will check the valves tomorrow. this thing i'm guessing is around 10 years old. i'm wondering if it does need rings. I will dig further into it tomorrow. thanks for all your input.
