What is the best cold weld product to repair a pinhole leak on the bottom of an oil pan?
It’s a 2006 Jeep Commander and to replace the oil pan the entire front axle assembly needs to be removed.
There is a small patch of rust the size of an apple (from where the pan must touch the skid plate). There is a spot about the size of a quarter that looks pretty deep. It drips oil just a little little bit so I’m assuming the quarter size spot must be even smaller from the inside of the pan. I lose about a quart of oil in 3k.
JB weld or Permatex? What particular blend (of whatever one) will work the best.
Will cold welding even work?
Any tips if so?
Can the mechanics across the street do an actual weld?
I saw a guy recommending a fiberglass repair will that work?
Here a video https://youtu.be/XObmZIbHOzY
I like this guy he like the scotty of reviewing product for me.
The problem you will face ....
If you plug the hole with product x or weld
There a change that material can come loose and clog something like your oil intake.
I would do the hard yard and repair it right or live with it..
There are fibre kit that can fix this but I have not used use it and other member may be able to help u.

Thanks for the link to that guy. You’re right his videos are pretty good I see after taking a look at him. The video you linked was pretty helpful. Looks like I’d use the original JB if I do that route from what I see there. Can’t believe how much better it preformed than the new quick welds and stuff. I was going to grab the high heat stuff most likely if not for your link. I am in no position to do the hard work or pay somebody else for it so I’m either going to ask a mechanic for a hot weld or use JB. I seen a video where a guy uses a small metal dish that he cold welds to his oil pan by the flanges. He resorted to this because oil was continuing to drip out and not allowing any compound to stick. The oil then drips into the dish as the cold well cures onto clean metal. That route should eliminate most possibilities of any material being sucked into the oiling system. Probably even coat the remaining rusty pan with oil in the dish and prevent future rust. Hopefully I can find a dish that will fit with the skid plate.
Btw, Jeep commander owners, take your skid plates off occasionally to clean out the dirt that builds up in them. Mine had a solid inch of built up dirt that contacted the pan and caused the rust.
Other stand good to know and let us know how you go. It all about sharing ideas with each other.
Sometime coming up with creative solution is the best and you learn so much.
Good luck
