Before you get a new one, take off the old one and JB Weld it. Did it to mine 2 years ago after I put a significant crack in it (don't ask, I was being a dumb 17 yr old). Did taht as a last-ditch effort and has held since, no leaks. The gasket has leaked ever since (yes, I made sure it was not the crack) and I tried to put a new one on there and with the limited tools I have here I ended up having it towed to the delaership for them to fix it and it still leaks aftet $259!!! Anyway, try the JB Weld, If you clean it up good it should be ok.
