Default 7.3 oil pan leak.

A friend of mines 99 7.3 is starting to leak, has anyone used por 15 and had good luck on a pan as opposed to changing that pain in the ass pan?

Por 15 WILL NOT seal the pan against leaks.

there are a lot of temperary solutions, but they are just that; temporary.

Buy a pan, fiberglass the outside of it, then spend a weekend to do it right.

i seen a guy who got a bunch of jb-weld, mixed it painted the pan with it, and he said it is going strong with no issues.

you cam also cut out the cross-member, replace pan and weld cross-member back on

Yep, just pull the motor and do it right. Then you can replace the turbo and pedistal orings and up-pipe gaskets at the same time.

If it is leaking it is too late. Time for a new pan.

if your pulling the pan, I would also suggest replacing the rear main, and resealing the cover behind the rear main, which the oil pan seals to...that one just recently bit me in the ass...there are also a couple o-rings on the oil lines to the injection pump that leak into the lifter valley, run out of a weephole at the back of the engine, and then drips off the corner of the oil pan near the starter, which makes it look like a pan leak, and those are a common problem.

I would replace it. Someone had jb welded or some jank crap on the bottom of the oil pan on my truck before I bought it. You may as well fix it before it blows out while your going down the highway 1.5 hours from home.
