I just got my 110 motor put back on my frame after a complete rebuild.When i start it and run it for about 10 mins. you can take the dip stick out and it is under alot of pressure.So i drilled in the top of the case by the dipstick and put a fitting with a piece of vacume hose on it to vent it but it shoots oil out of the end of the hose.the motor is only half full of oil because i drained some out.even whith it vented while it is running it still will want to blow out the dipstick when you take it out.Why is it doing this and how can i stop this? I am begging for help and answers.

 

The engine is supposed to have pressure in it to keep the gears and stuff oiled. If it don't spit oil out the dipstick hole while it's running there is something wrong with it..
As long as it don't do it while it's not running it's alright.
Just plug the hole it will be alright....

I remember seeing on ebay dipsticks for the 110 that had a built in pressure valve so the pressure would be released. But I really don't know if the motor was disigned have such pressure.
