Question about Ford F-150
My problem starts with the oil pressure. 1994 f-150 4x2 5.0 v8 has over 175k miles on it. Truck has always been in good condition other than minor replacements. Motor tranny all run smooth. Untill a couple of months ago i started to lose oil pressure on the highway so i stoped went home changed the oil and it was fine. The other day happened to me again after it had been driving for 25 minutes or so. When pushed to about 1500 rpms lost all pressure, but let go of gas gained it all back. So i changed sending unit and oil now still does the name thing right when i start it up. So its seems to be the oil pump but i cant figure it out for sure until i get the pan down. The thing is its going to be alot of work for me. Ive done plenty of work on it, had the y pipe off before and replaced a manifold so its all about lifting the motor. Question one is it has over 175 thousand miles so is the engine ruined
now that this has happened and is it worth the money considering its
history. Question two is should i try doing it or is it worth trusting and paying someone else to do it.
All advice appreciated.
If it has oil pressure at idle I would say the pump is good. I would try hooking up a mechanical gauge(oil pressure tester) and drive the truck with this on it to verify the pressure. The funny thing is what you are describing to me sounds like a restricted oil filter.
