maybe some of you know what the problem is. after i shut it down i hear a lot of pressure comeing out from around the dip stick.

 

Maybe the oil screen filter at the bottom of the oil tank is clogged?

 

Maybe a new oring is in order there is presure in the tank and more than likely your oring is dirty or damaged you might want to check you crank case ventalation tube too make sure its not pluged or obstructed and is releasing presure as it should .

 

well the crankcase vent tube should let the pressure out so i would check that

 

Are you sure it's not the radiator overflow spitting out some steam? check you water..
