Oil Pan Leaking

Does the lower section of this oil pan come off from the main bolted on part? I just did a full rebuild and have a small pinhole leak coming from that seam circled in the pictures. I was hoping I could just take that lower section off so I don’t have to drop the differential and replace the oil pan completely.

 

Your screwed. Common place for leaks gotta drop differential to replace pan.

 

Not what I wanted to hear.

 

I’d patch it - lots of good options with adhesives - fuel tank repair kit would do it.

 

Oh, I’m considering that. Any that you would recommend?

 

I used this on a friggen drill hole in my steel gas tank some nice people left for me on my 1st gen - I sold the truck 75k miles later with no tank issues:

First clean the heck out of the repair area with acetone, then scratch it up with rough emory paper or something to give the glue some more bite to the metal, then a final clean with acetone.

Also drain the oil before cleaning it and let the glue fully cure before refilling it.

 

Id stick some fiberglass window screen in the epoxy kinda like rebar. I know there is a epoxy they use on airplane fuel tanks thats supposed to kick a** ! Dunno the name of it though. Good luck and let us know how it goes. Mine is leakin from same spot!

 

I bought some of the JB tank weld and gonna give it a go tonight when once the kids are in bed. I’ll let it cure overnight and see how it looks tomorrow

 

The truck has been filled up all day today and driven a few miles. It hasn’t leaked any so far. Here is the steps I did and it seems to have worked.
1. Wire wheeled the whole seam
2. Blew it all off with air compressor
3. Cleaned with brake cleaner
4. Hand sanded with 60 grit sandpaper
5. Cleaned with acetone
6. Applied two tubes of the JB tank weld and made sure to try and mash it into the seam really well.
I went ahead ordered an oil pan that I will stick on the shelf and have for when the job needs to be done. For the meantime, it looks like this will work. Hopefully it will make it to the winter and the shop won’t be 100 degrees.

 

I’m sure it will last a long time- I had the truck patched up like that for years before I sold it with no leaks. Gas tanks bulge and contract a lot so the glue did really well, plus my patch covered a drill hole- much larger than yours.

 

Im rooting for ya!

 

That was a fun one to learn..

 

Ok, I just got done doing the same repair. Drained oil for 2 days. Wire wheeled the whole frickin seam which was all rust. found an actual pin hole i stuck a sheet metal screw with rubber washer in. Cleaned the heck outas everything with degreaser and hand sanded all the rust off with 80 grit emery. Mixed up some quick setting JB weld and brushed it on while creating a vacuum with shop vac on drain hole to try to suck it in seam. Then covered everything with JB steel stick and painted chassis black. I`ll keep everybody posted on my luck with this repair also.

 

I’ve gone 500 miles with mine and it has t leaked a drop.

 

Aren't these steel? Nobody nearby can weld?

 

two piece pan welded seam that rots out. Only way to weld would be removal of pan and at that point it would be foolish.

 

Temporary fixes pile up into mechanical tech-debt. When you decide to sell or overhaul your truck, that tech-debt can be a real problem. That being said, I know it's a real pain because the front differential will need to be dropped but you should replace the oil pan. Do it the right way. When I run into these problems, I try to see them as an opportunity to service other nearby or related components, and I try to remember that I am saving myself future headache.

 

Mine is a temporary fix until winter when I can pull it into the shop when it’s not 110 degrees. The spare pan is already on the shelf. Gonna drop the differential and replace both cv axles while I’m in there. It is worth $10 and 30 minutes of prep work to not have to do the whole job in the middle of the summer.

 

That makes sense, and that is what I would do, too. I hope my earlier response did not sound condescending; it was intended to be encouraging

Good luck!
