weld in oil pan drain

[maggies man]

I just bought a 1993 w250 ex cab w/ 130,000 miles on it that I have been watching for ten years. The threads on the oil pan drain have been pulled, and a repair is needed. I know about the Fumoto drain plugs from another thread, but, since the engine is coming out on Monday for some gasket repairs I am thinking about the possibility of welding in a new bung, Anybody ever done this repair, any advice, guidance would be appreciated. Thank You in advance. Pat

Its just a matter of makeing it not leak !!! but i think a used oil pan can be had cheap !!!

The pan is cheap but a ***** to change in truck. The U shape crossmember under the pan makes it impossible to drop enough to clear the pickup tube.

Step 1 in the service manual from Chrysler under oil pan replacement actually says:

Step 1: Remove engine from truck.

Did you miss this: " since the engine is coming out on Monday for some gasket repairs I am thinking about the possibility of welding in a new bung"

Not fully. Wasn't sure if the engine was FULLY coming out or not. If not, it was a suggestion to.

A new pan from cummins west is $484.00. A used one I saw on E-Bay was $100.00. Thats why the welded bung question. May just go w/ a Fumoto after all. I didn't have any luck getting the pan out with engine still in truck, must have done something wrong. Anyway, its out now and being worked on. Thanks for the replies, will keep checking back.

the oil leaks from the pan gasket and the timing case gasket have been fixed. Didn't do anything about the bung hole threads. the plug doesn't leak when I use the hard pressed paper gaskets and tightened not to tight. Have a Fumoto plug on stand by, just in case. Drive way is as dry as a bone underneath the truck. This is one sweet truck I just bought, so I am going to sell Old Betsy, after 15 years. Good old 4x2. Never let me down.

You can also buy an oversized plug that will retap the hole as you install it.

I've welded in a couple. These local farmers are hell on their oilpans!! Removed a t-post from one 6-7 years ago.... A good TIG or MIG welder, turn the gas up, and weld it in. I like to plasma torch a larger hole, and reinforce it with a 4x4" piece of sheet metal.... maybe larger if there are a lot of dents I have to knock out!! Weld up both sides and fill with water after it cools to make sure it doesn't leak.

For taking the pan off, it's a Mamajama, for sure. In a first Gen with an auto transmission, the engine can be lifted several inches and with the crank turned to the correct position, it will come out.... It's a lot easier without a transmission on it, and that's a big part of taking it out.... I find that most of the older trucks today have settled in the cab mounts a little, and it's impossible to lift the engine enough with the transmission connected..... Standards are a no-can-do with the transmission on it.

If it's ain't leaking, it ain't a problem!!
