Excessive crankcase pressure

Bairdfamily6 · Apr 24, 2020

Hello, I have a FSM with front loader and backhoe. I have alot of pressure resulting in oil coming out of the crankcase breather and pushing out the dip stick. The valve cover tube was plugged and got that done and cleaned and replaced the air cleaner still not luck. I currently have the decompression lever off so it doesnt blow oil everywhere. Any suggestions?? No water in the oil or oil in the water. Im lost here Thanks Mike

Did you clean under the valve cover, could possibly be plugged up under there.

Yes, I cleaned out everything.

Could it be head gasket failure?
Or glazed bores caused by lack of hard work ?
Is cooling system ok?

Is this something that just suddenly happened, or has it been gradually getting worse? Either probably indicates the need for a tear down. Gradual would show a possible need for rings and sleeves. Sudden, broken ring or rings, cracked piston, head gasket into an oil gallery?
