Hey everybody,
Ive got a 91 f150 with a 302ci 5.0L motor. My problem is that i keep getting gas mixed in with my oil. Its creating a lot of foam and a real headache. My check engine light came on and i found out that my throttle position sensor is shot. If this is not the problem, does anyone have suggestions?? I dont have a clue.
thanks

ps, if anyone has the same truck as me, do you have to take the intake manifold off to access the valve covers, or is their an easier way to do it???

 

The TPS sensor is not related to fuel in the oil.

It sounds as if the rings in your cylinders are shot, unless there is a drastic fuel passage route problem ???

 

pull the vacume line from the fuel pressure regulater and see if there is fuel in the line, if so the pressure regulater is bad.

 

ime not familiar with the 91 model, what kind of fuel pump is it? And to check the rings just take the oil fill cap of while idling there shouldnt be excessive blow by pushing out if the rings are ok.
