So had the sled running today for about 15 mins. Got it shut down and noticed a very slow drip from the bottom of the rear tunnel. So i check it out and i find a TINY. And i mean tiny crack in the heat exchanger. I am tryin to sell this sled, but if i dont i plan on riding it. Is there anyway to do a patch for something like this. Or is it a whole new part kind of thing?
