Well after 285,000 miles it did it!
98 F 150 4.2 v6 Driving back from town and my oil pressuer gauge dropped to the bottom and the oil light can on. So I pulled off the road and the truck stalled. So I sat for a few min's and started it back up still no pressure but the truck ran. So I limped it the rest of the way home ( 1/2 mile) and and watch the temp gauge the whole way ( no movement) got it home and it stalled again. So I checked the oil dip stick and the fluid is a gold color. Called my Mach. and he came over and said it might be the head gasket. He is going to start to tear into it Tuseday morn. Hopefuly its just the gaskest. but with my luck this year it's going to be alot more.

Think that NO pressure warrents checking pressure with a gage first before tearing into an engine, just looking?
I think you should be looking at the sender switch first.
It's located behind the oil filter.
And get another mechanic if that is the best he can do as the first guess.
NOTE: If the motor got hard to crank over, stop. It maybe seizing up for lack of oil pressure that would be an internal problem but still not normally a head gasket.
Good luck.

As others have mentioned, you need to confirm the oil pressure with a mechanical gauge first. Might just be a bad sending unit. I'd cut the oil filter open and see if there's any metal in it. When he said that the oil had a bronze color, did that mean there were particles (copper) in it or did it have a bronze tint like clean, new oil?

what has FRAM got to do with it ? Filters do not explode and plug ports. I would drain the oil and remove the filter. "bronze" dirty oil means very fine particles of brass suspended in the oil. see if you have any flakes in the drain. Im guessing that the oil pressure is actually very low, possibly zero. If thats the case, you have spun main bearings. The original gauge is on- off. It really does not read pressure, it turns on and off at 8 psi. If you have 7 psi- it reads zero.

I bet what happened is your intake gasket started leaking coolant down into the engine. Even after Ford supposedly "fixed" this issue with a thicker gasket, they still do it on occasion. That would have thinned your oil out slowly and could have easily burned up the bearings from lack of lubrication. Its a 4.2 thing.
