Temporary Repairs will not hold for long such as JB weld. You will need to remove the oil pan and have it welded or just have it replaced. It is only a 2 hour job to remove and replace the oil pan. A new Oil pan sells for around $175.00 US. If it is only cracked in a small area, get it welded. If it is all beat up, replace it.How to Repair My Cracked Oil Pan?
Ive used a liquid metal product like jb weld to repair a sump before but only as a temporary repair.If its just a crack and you dont want to take the sump off,find someone who can braze.Youll have to drain the sump,brazing is good for cracks as capillery action will draw the braze in sealing the crack,permanently.
it can be welded whether it be aluminum or steel or replaced ,i have welded a lot of pans up though and never had any problem's from any of them,its better if you have the option though to replace it,jb weld is a temporary repair in most cases,i wouldn't trust it as permanent repair,good luck.
I would recommend replacement as it is a longer lasting and safer way to go.
but if you insist I would go with Water Weld or J-B Stik as they are putty-type epoxy. regular J-B is better suited for bonding pieces together, like a fitting to a pipe.
ive used jb weld before on a tranny pan and it worked, but you have to drain the oil and sand it down good so it will stick, let it sit for about 2 hours, before filling it back up. i had that car for 11 yrs and it still was on there when i sold it.
JB weld is only to get you home. The pans expand and contract too much for that to hold. They don't cost much. The problem is that some of them are a bear to get off.
They are not repaired. the are replaced.
They are not expensive. If your ';repair'; job was to fail, you would leak oil and have VERY EXPENSIVE engine damage.
Good Luck....
REPLACE !!
