I see this sort of thing on aircraft from time to time. The softer metals will eat into the harder metal. I know it hard to believe, but I have seen rubber grommets eat thru steel lines on engines from vibration. Thats what happened here. Poor fitment, rubbing, you got a hole...

A good welder should theoretically be able to weld the hole shut, but it might be difficult being that it's cast aluminum. How big is the hole? The pic's a little too fuzzy to tell.

Here's a fact:
If your downpipe temp exceeded the melting point of your T-case nyou should consult your local University for unexplained plasma emitted temps from a car's exhaust.
Your dealer is a lying dirtbag if he honestly said this
Good luck

I haven't touched anything yet since a guy from the dealer is coming back out to look at it. I am leaning towards sewing the dealer for 5k if they decide they aren't going to do anything and buy that 6 speed with transfer case on it. Like mentioned earlier. I have no idea how long this has been ran dry and what condition the transfer case is in. The point is they sold me a car with checking over it. Also they didn't check off the sold as is part in the papers. They have no chance.

It could have been a combination of high temps and constant rubbing that actually wore it down. Friction and heat will eventually do serious damage. I think the melting point of aluminum is only something like 1200 degrees. Exhaust temps at WOT can reach 1400-1500 degrees farenheit in the exhaust manifold on a stock 4G63 (In a DSM at least, never gauged hte evo's engine). Granted the exhaust cools significantly by the time it reaches that point in the downpipe, it's still hot enough to heat the aluminum to near it's limits. It's not entirely impossible that the heat at least played a major role in the hole.

There is no hole. If anything it may be cracked, or maybe some of the gasket material has melted away causing the leak. There is absolutely no way there is a gaping hole, but if there is, you must have a problem with gremlins like my DSM's do =). Post better pics so we can see!
Here is an idea, go to autozone, buy some Ultraviolet dye, stick it in the transfer case. Take it for a short drive, and shine a black light on that area (when it is dark). You will see exactly where it is coming from and how large the leak is.
