Smile 7.3 4x4 OIL PAN REPLACEMENT

Hi,
While I was checking the underside of my truck I noticed the oil pan is all rusted and looks bad.
What does it take to replace the oil pan on a F-250 4x4 7.3? Engine off mounts? Total removal of engine? Drop front axle???
Thanks,
Mike

2 things:

First, has anyone wire brushed the oil pan rust and then applied Rustoleum rust converter? Obviously the pan rusts from outside to inside and I would imagine if the metal is not paper thin a converter should work fairly well. The Rustoleum converter works WAY better than Rust-Mort.

Secondly, if you do need to replace the oil pan, shouldn't you be able to remove the motor mount bolts, the trans crossmember bolt and jack the engine up high enough? I know its been done on F150's this way for years (obviously the exhaust has to be removed)

The engine has to be turned upside down for 24 hours for the sealant to cure. If you do not seal it correctly, it will leak. The only way to guarantee no leaks is to pull the engine.

Exactly. The guy who owned my truck before me tried to fix it without pulling the engine. He cut the cross member out and dropped the oil pan, replaced the oil pan with a new one and went to town the the grey RTV sealant. Now I got the truck, it leaks now from where the oil contaminated the sealant. I got the engine out now doing it the right way.

What sealant is used? There HAS to be another way other than pulling the motor and turning it upside down. Ford doesn't have a monopoly on oil pan replacement from rust or damage. Why would you not be able to remove the pan and leave it off for a day or two in order to let all the oil drain out?

If you want it done right you have to pull the motor if you want it to leak you can do it with the motor in the truck.
