Well I took it to work for him and had one of the guys heli coil it for me because he's good with that stuff. He put some sleeve retainer on the helicoil and I put a tiny dab on the banjo bolt when I put it back in for him, along with a little blue silicone on the new copper washers. So far so good, it hasn't leaked. So hopefully it will hold for him. Best part is my buddy from work had one of those heli coils laying around, so my friend didn't have to buy the kit for 50 bucks.
