Default Re: Losing oil through breather tube

It is blow by. Usually they will not blow oil out if you use the proper amount of oil: 1 qt. If you use more they will all blow oil out into the airbox. Older carts may be worse due to more blow by. The engine does pump some oil up there to lube the rockers and valves. The dip stick is not always right, and is usually closer to half full on a lifted cart when it has 1 qt in it. You can put the hose into a catch can, and plug the airbox hole, but it can be stinky that way.
