JB Welding an oil pan

[mr ilia]

I'd say do it. I JB weld where I can. From all my car years I have sucessfully used JB on punctured from the bottom gas tank, turbo oil drain in the oil pan, A/C condencer. The A/C condencer is a bitch, since the system it is under preassure and the pinch hole was in the tight spot to reach....so the preassure slowly leaks out, but I do not see this a huge deal, since a/c is not used for more than 3 months of the year for me. I just do a refill when needed.

Had my cam replaced in the MKV GLI back in 2009, somehow on that visit I received a small crack in the oil pan. Looked like someone jacked up the motor by the pan but didn't put a block of wood between the cup and aluminum.

Anyway, I drained the oil, cleaned it up, lathered some JB on there and it held until the end of 2011 when a rod smashed through the engine.

I've done this just once when a friend hit a rock while we were out camping. Cracked the pan, no tools available, needed to drive 200 miles home. Even with two days of draining and wiping and 24 hours to cure, it leaked all the way home.

The JB weld will only work if you remove the pan and completely clean and degrease it inside and out around the crack. Since you're doing all that same work, just replace the pan or get it welded.

Guess I was imagining things.

Seriously though, if you pan is pissing out oil don't expect JB weld to help. There's a difference between a crack that is dripping slowly and a hole.

I have an oil pan I'll sell you cheap. Don't half ass stuff man. If a shop said they could weld it without taking it off the car they are full of it. Unless you pull it of, thoroughly clean the surface, that weld will be so full of porosity it'll be like an aluminum sponge and slowly leak oil.

Don't waste your time, money and oil on jb weld. Get a different pan.

Edit: reread your first post, not sure why I thought welding was involved. If you do plan on buying a new pan, spend that $100 the shop quoted on a tool set, then get a pan. If you can't keep oil from contaminating the area you're patching the jb weld isn't going to do it's job.

I payed under $50 for a new pan and gasket. Why would you pay $100 to fix a broken one? I must be missing something.

New oil pan. Engine hoist, drop subframe. Replace.

i had to jb weld my oil pan. has lasted about a year, just drips so i keep an eye on my oil level as I should anyway. just get it as clean as you can and be liberal with the jb weld. as long as its only a temp solution you should be fine.
