1950 FORD F-150

One day I added some oil in my 1992 F-150 to find a white-ish jell under my oil cap. I figured it might be a blown head gasket or crack in the manifold. It might be water or anti-freeze. The truck has 182,000 miles and its automatic. The truck burns a little oil, but when I am going about 25 mphs the oil presser drops down when I left off the gas and it likes to bog down or ride pretty rough when this happens. NOT really sure about it. :Lol: hoping you could give me a fews answers on the situation because its pissing me off not knowing whats going on.

Pull the dipstick. If it has the same creamy froth on it instead of oil you might have a blown head gasket. Screw a mechanical oil pressure guage into the block and test the oil pressure that way. Ford oil pressure guages are really idiot lights connected to a stick. Anything from 7-80psi will register in the middle of the guage. Anything less than 7psi will read zero. You probably have SOME oil pressure, so use a mechanical guage to get an accurate reading.
