Help...Cracked Oil Pan

[Hivolts]

Anyone know what I might seal a 1 inch hairline crack on the bottom of my oil pan with? Not sure which jb weld product or steel putty may work best. Thanks.

how did you get a crack in it an if i was you i would replace it welding that is kinda risky

For the relative ease of access to the oil pan, I tend to agree that replacement is the best repair.

I would deff replace the pan, supposedly it is not terrible to drop the pan on these 6.0's

I just need a temporary fix. Could I weld it while its on the truck? The oil is drained. Oil pan got in a fight with a rock and lost.

If the pan is cracked enough to cause a leak issue, you will be hard pressed to "Band-Aid" it successfully with a weld. For what it's worth, any successful welding (be that with JB Weld, MIG welding, Oxy-Acetylene etc.) will require a clean DRY surface to work with. In other words, with the pan on the truck and oil leaking through it during the process, the likelihood of success is slim to none.

I mig welded an oil pan on a racecar with gasoline-loaded oil still in the pan.

It went rounds, but you had to have the heat WAY up to dry the surface as you weld it. Dangerous as hell, but if you think about it, if there's no air in the pan, no chance for combustion. Right? Right?

Don't be like my buddy Tom with 8ft of brake cleaner fire shooting out of a drain hole while you're welding up the pan

WHERE is the crack in the pan?
