Leaking oil

[Bryce1217]

Hi everyone. I purchased and broke in a predator 212 hemi around 1 year ago. I just put on a frame with an old torque converter but never really had the chance to run it much. I recently ran into a little bit of time so I decided to put a new torque converter on it and an exhaust pipe, intake and the jet that comes with the set on gopowersports website. When disconnecting the airbox to put the new air filter on, I just left the vent tube for the gas tank and valve cover hanging down. Now, when I run the kart hard oil shoots out of the vent tube coming from the valve cover. Is this normal? I've lost quite a bit of oil, and according to my dipstick I am not over full. Is there a fix for this? The oil usually doesn't shoot out at low rpms or idling, just when ran hard.

That's a good way to wreck and engine with out a air filter on that little tube... Have you tried pointing the tube up? Pointing that tube down makes it really easy for the oil to drain out...

I had no idea that you were supposed to have an air filter on it. Yes, I tried pointing air filter and oil still came out. Is it normal for oil to drain out of that tube?

heres how i have mine set up... its just a cheap little fuel filter atached to it... If oil start draining out on mine it simply falls back to were it came from... idk

if you dont have some sort of filter on the litlle tube dust and stuff can get inside the engnie and damage it ect...

It is normal for oil to drain out if you over filled the oil.. if the oil is not over filled I can't help you..

According to the dipstick it isn't even close to being full, and I followed the instructions in the manual when putting oil in for the first time. Do you think maybe a one way check valve would be a good idea? It would allow air to pass through but not oil to drain out. I could then put a filter over the check valve.

That's the point of the filter, it lets air pass through (in BOTH directions) but traps the oil...

The tube is a crankcase breather; it prevents positive crankcase pressure which damages engines & hinders performance...
