Default 7.3 super duty oil pan

I've noticed a drop of oil under my truck after it's parked overnight. I haven't crawled underneath to check it out yet but I know it had some surface rust starting last time I was under so I'll prepare for the worst.

Should it be time for a new oil pan is there a way to replace it without pulling the motor? I'm not really interested in chopping up the crossmember since a. I only have a 135 amp mig welder and b. I don't want to cut up structural parts on a truck I plow snow with.

Are you sure its the oil pan and not the lines?

I smeared Grease all over my oil pan every time I changed the oil to keep it from rusting, we used to do that with a lot of our heavy equipment years ago when I helped to maintain a fleet of trucks at a construction company to prevent the pans from rusting. We'd paint them and then smear wheel bearing grease all over them.

Unfortunately, the only right way is to pull the motor, I normally replace up-pipe gaskets and oil cooler O-rings at the same time. You will need to remove the turbo so get O-rings for that and the pedestal. The pan gasket should be ultra grey RTV and I normally sand and re-paint the new pan as what comes on them is very thin.

I'm not sure yet it's something I have been curious about though since I know it's a weak link on these trucks among other things. It is due for an oil change pretty soon so I'll check it out at that point.

If it isn't the oil pan I will get some por 15 and start using your method

Yeah, I thought my oil pan was rusted through but it appeared to be actually leaking from somewhere above the pan on the back of the motor on the passenger side.

It could also be your dipstick where it comes out of the oil pan. They sell repair kits for those which are about $300. You can do it without removing the oil pan too.

Pull the cab.
Lift the motor up about a foot and the pan comes right out.
Done a couple that way.

Except pulling the motor on those trucks is a lot easier with the cab removed.

I pull the trans, lift the motor up and the pan slides right out. Easiest way to do it IMO.

Pulling the motor or pulling the cab takes a lot longer

The motor comes out in about 3hrs labor. Its actually pretty easy. You don't have to pull the cab. Take the front end off. Disconect the trans and support it. Pull motor out. Only pulled mine cause I blew the trans but while it was out I did a pan and head studs. Nice part is you can make it pretty while its out. I drove my truck for ten years and sold it for what I payed for it lol
