F-150 Oil Pan

I replaced the rusted oil pan on my 1993 F-150 4.9L (2Wd 5-spd). It took 4 hours. Probably a pro can do

it in 2.

My repair manual (starts with an H) listed extra steps like: remove the radiator, remove upper plenum,

and remove starter.

Actually there were only three things to unbolt besides the oil pan:

1) the positive battery cable 2) the cooling fan (with clutch) 3) the windshield wiper motor (unbolted, and not completely removed)

I avoided removing the plenum buy moving the windshield wiper motor clear of the plenum. I had to wiggle

the pan to get it out. I didn't have to force it, just position it exactly.

Here are the detailed steps I took and some annotated pictures:

Some things about having a six are nice. The job is a bit less difficult than with a V8 because of the exhaust and the location of the oil pump.

I wonder if this procedure would work on a 1995 F-150 with the 5.8L V-8. I also had a rusted oil pan and have solved the problem so far with a good amount of carefully applied JB Weld. It's been fine for about a year with this repair. I suspect I may have to replace the pan eventually so it would be nice to know that it wouldn't have to cost the $1,200 estimate I received last year.

The problem with the V8 is the location of the exhaust crossover and the oil pump. You have to be able to drop the pan down and move it back and down to remove it. If you don't mind have a muffler shop do a bit of repair of the crossover, you can have a sleeve made to go over the crossover pipe. Cut the pipe to the right before it necks down and remove the left portion of the pipe to allow the pan to be dropped to the back. Have a muffler shop or someone who is good with a wire welder to re-connect the two halves of the crossover. Removing the upper intake will allow the engine to be lifted high enough to clear w/o messing with the wiper motor which won't do you much good with a V8 anyway. The upper intake is actually quite easy to deal with once you rig up a torx bit to get the center bolt out. With the six, the location of the oil pump is further back allowing the pan to come out the way he did it. The pump is at the front of the V8 requiring the the pan be dropped down before sliding back and out. The six also does not have the exhaust crossover to deal with. A cherry picker hoist makes the job possible.

I purchased a new oil pan from Ford for $100, removed the original paint with an angle grinder and wire wheel, and repainted the pan.

THERE WERE CLEARLY VISIBLE BROWN HAZE AREAS UNDER THE ORIGINAL PAINT which I removed with a second, much more forceful, pass of the angle grinder (photo below). One coat of Extreme Performance primer and three coats of "baked" enamel were then applied.
