Oil Pressure Help
Ok i start the 351 powered automatic 92 bronco up cold 28* F I start down the road and i see the pressure gauge drop to nothing, Figured it was the gauge going bad like my other 92 has. So i keep going on to work cause i knew the oil was full.
3 miles down the road it starts to get noise so Now i know it is not the gauge it is in fact no oil pressure. so as i get off the road i hear a screeching noise then it goes away, ( I hope i didnt spin a bearing) then i shut it off wait 30 sec. and restart it and just like that it has oil pressure and the lifters pump up and all is well.
What happend???/ I thought maybe the drain holes were pluged and all the oil was up top but i feel in that case it would have been smoking do to oil getting past the valve guide seals. so my next thought is crud sucked up to the oil pick up.
What do you guys think? Am i on the right track?
This is a truck i use to plow snow it has 152K on it.
Can I get the pan out without pulling the engine 351 E40d trans?
I need some input thanks Dave

AMEN! to Kem. Start with a mechanical oil pressure guage. I screwed a 1/4 X 6" brass nipple into the block then hooked tubing to it. Is the correct oil filter on it? I think it should have a bypass valve in it but not really sure. If the filter is plugged with cold oil the valve in the engine may dump it back into the crankase with limited oil flow through the galleries. Motorcraft filter seems popular in this forum for better flow and I use it. I went with Mobil Clean High Mileage 10W-30 to slowly clean without breaking chunks loose and plugging the oil galleries or screen.

more then likely not. but you can atleast try by hoisting it up as far as possible. it will take some time for sure. ive heard if you get the pan loose and then remove the oil pump the oil pan will then come out.

well it had oil pressure all the way home from work, I changed the oil and filter it looked like normal oil, Im lucky enough to have a lift in my shop at he house so i took a good look and it dont look like you can get that pan out with it in the truck.
Im going to try it with the new oil and filter and see what happens.

Supposedly if you take the upper intake off and take the oil pump loose you can get the pan out, but the E4OD length still cause clearance issues because it causes the valve covers to hit the fire wall before enough room is had in the truck.

I have a 88 bronco with a 5.0L. Had oil pressure problems and it had took out the main bearings and rod bearings. Ford is known for having problems with the 5.0 and 5.8 with oil pressure. If you look at your gauge it nomally sits on the N or the O of normal. When I replaced the crank and bearings I had upgraded the oil pump to a high volume pump. My oil pressure now sits between R and M of the gauge.

Someone on here awhile back said that the stock oil pressure guage is just an oil presure switch. Meaning its either on or off. (A higher reading is not higher pressure) I dont know if its true. BroncoChris's experince would seem to indicate that its not. I hope its not, but I wouldnt put it past them.
