How does it get to the oil pan? If it leaks in the intake won't it run into any open cylinder and either evaporate or puddle in the cylinders until the carb is empty? The most it would be is an ounce or two of fuel. If you have fuel in the oil pan then it may be leaking at the fuel pump diaphram that is lower thean the fuel tank and it can keep on leaking key off using gravity from the tank and dumping into the front cover and then to the pan.


This just happened to me. Changed the fuel pump and voila...no more gas in oil.

It fills the combustion chamber sits on the piston then works its way around the rings to the oil pan.......I brunt a F150 to the ground because of this one time.
