I found a leak in my brand new Milodon deep sump 7 qt oil pan. It's leaking at the front from the weld where the extension piece is joined to the base. It appears to be a very small hole, to small to see, but enough to allow a steady slow weep. Do I need to get this re-welded, or can I fix it with something like JB weld?
-
For a leak that small you can certainly get away without rewelding it. JB Weld would be a good choice, and so would a good silicone sealer. Drain the oil and get the area around the leak super clean and roughed up before you apply the fix.

You may want to consider this... JMHO

OK I like JB WELD products ,just used some lastweek to repairsome thin, But I had to laff reading the page about the "high heat" for use on wood?
Does it really Help heat resistance of wood ?
-
If it truly new, meaning you just purchased it, I would contact the manufacture fro replacement, assuming it was not damaged during install. You paid for a non-leaking pan why settle for a leaking pan.
-
Seen that before
And yes - JB or similar works fine.

I had an oil pan with an old weld repair that only leaked when hot. I don't know if this was due to the hot oil being thinner or expansion of the metal at the weld opening up the crack. Anyway, just a though that you might warm that pan up a bit with a heat gun or heat light before applying the JB just to be sure it finds its way into all of the small spaces.
-
Thanks for the replies. I might give the heat gun test a go, might as well check and repair it once. I have some JB weld, so saves me sending it out to be welded.
I bought the pan new a couple of years ago from Summit. However, seeing as I am in Australia, I'd rather just repair it than try to get a replacement, which may also leak.
-
When I did one with JB weld I drilled a small hole where the leak was so I could push a little into the pan to act as a rivet would. In other words it wasn't just sticking to the pan, it was held in by the JB weld on both sides.
-
How about contacting Milodon? If its new, and they are willing to repair or replace it, I'd pull it off. More of a pain of course, but it is a new pan after all

Hehe, reminds me. we got these V12 C32 caterpillar engines installed.
After 500 hours this massive coolant tank on the front had a crack. So myself and another fella spent 6 hours changing out the 250lb pig of a tank.
Anyway I hate these new engines, 25 coolant lines and apparently 150 bolts go into this thing from all different angles.... Tighten one bolt more than finger tight and none of the others will fit in. What a pain in the butt.
So after the 6 hours of changing it out we install the new one, fire it up and as soon as it got hot, it had a leaking weld. Cat refused to weld it in place, they wanted us to pull it back out and send it off and they'd give us a new one.
I got pissed and hit the leak with a hammer and it stopped leaking.
That was 22,000 hours ago.
The End.

LMAO!! Reminds me, though of a pair of factory SOHC heads that I had, that had been welded long before I got them, and were leaking in one spot near the welded area in the roof of an exhaust port. I took it to a guy who does cast aluminum and cast iron welding in my area, and rather than weld it he took a hammer and a punch and peened the welded area around the leak. Then he stuck it on his leak check fixture and Presto - the leak was gone! I watched the whole thing, and couldn't believe it. I ran those heads successfully on my first SOHC project...

I worked as a certified pipe weldor for many years.
And i must admit that i have centerpunched a few
leaks thight ;) :-X :-X :-X
Takes thicker material than a oilpan though
-
For gas and oil leaks I use stuff called Sealall. Comes in a tube that looks like a tube of model car glue. It works great for gas, oil, water, pretty much any kind of leak, as long as its not a big hole. I've used it on gas lines, gas tanks, oil lines etc. You can paint over it when your done. They sell it here in Canada so I would think its available in the US and elsewhere.
