Ok so I have a crack in my oil pan about a hairline size... Do you think I should use jb weld or just replace it? What's your opinion on this? I've heard of people using jb on it and what not. Some says it last but other says its temp..

 

You could temp fix it with JB weld, but I would not suggest it as a long term fix.

I would never recommmend that you fix metal with an epoxy, only use it as a get by. I've used it on brake lines until I could get my hands on the new one.

 

Got it... Im getting a shop to weld it up for me... Took a while to find someone close to me that weld aluminum...
