crankcase pressurizing

[greg prentice]

Sears riding mower blowing oil out of the fuel pump. Replaced the fuel pump per earlier post. Pump is not the problem. The fuel pump has a hose connected to it that is also connected to the oil filler tube. It seems as though there is to much pressure in the crank case and it forces oil out the pump. The motor is a 18.5 ohc briggs. Thanks Greg.

I would check for a blown head gasket.

How do i check for a blown head gasket?

If you pull the dip stick while the engine is running, and rest it on top of the fill tube, it should not bounce up and down. If it bounces, you have a 90% chance that the head gasket is blown. The only other way is to pull the head and look at it. If you do this you will be replacing the gasket anyway. If you pull the head you will have to readjust the valves, I don't know if you want to get into that.
