Long story short I have a 3/16" hole/puncture to my tunnel and more specifically right along the edge where the cooling runs through. To get it off the mountain last weekend we used JB weld to patch it temporarily but am now looking for a permanent fix. I have talked to a couple guys I know who have decent welding skills but they recommend I find someone who is very good with a tig welder to ensure that the aluminum does not get heated up to much and make a bigger hole or end up with excess slag inside the hole (this would restrict coolant flow) If anyone on here does or knows someone who would be willing to take a look let me know and I can send you a couple photos and arrange to meet up. Thanks.
