Fixing an oil pan hole

[Kiel]

I recentley picked up a engine that has a hole poked in the oil pan. Everything is in good shape, just wondering if there is really a procedure for repairing an oil pan?

weld it up then put some jbweld over the weld - good ss new.

Be sure you pull the pan off before you weld. Chances are, there's some old gas fumes in there just waiting to surprize you.

Why not just replace it?

I don't want to buy a new one from the dealer. Plus all the ones I find already have a hole in them from rods breaking losse. But if you can find one for a 1.6 8 valve suzuki I will be all over it!

If you are going to weld it, you may as well add some extra plate and beef it up while you are at it. Maybe some 1/8" to prevent rocks from going through it next time.

Yep thats the plan is to plate that sucker.

I've JB Welded oil pans with great success, but I'm ghetto-fab.

I regular weld it first, then grind the weld smooth and jbweld over the top for a little more insurance, lets just say the first one still leaked after I fixed it.

The jackass' at Jiffy Lube ruined the oil pan in my Acura. "Uh oh, ummm the bolt won't go back in, you might want to have it towed home," was the worker bee's comment to me.... Anyway, I took a 1/2" nut and bolt, drilled the old bolt out and welded this sucker in place. It had a very small leak when I was done, but not even enough to leave a spot on the driveway.

Yeah this pan's drain plug is good, it just has a spike hole through it where they drained the fluids I guess. About the size of a nickel

I guess my point was just that it can be done, as I did it on mine. The only suggestion I have is get the weld as hot as you can, without burnign the melting the pan. Doing so will help fill any 'pin' holes or air bubbles. If you think you have some, take some black RTV on your finger and rub it around the inside of the pan (after cleaning it and the weld real good). Don't leave any excess, either. All you're doing is pushing the RTV into any holes that you might have....
