Did I blow my head gaskets again?
This past summer I had ARP's and Black Onyx head gaskets installed at the dealer after a diagnosed head gasket failure. The dealer agreed to install the head gaskets with the stipulation that they could not warranty a future head gasket failure. I gave them the go ahead and a couple days later I got my truck back with a fresh piece of mind. Fast forward to today: Towing down the interstate with my car trailer & car (about 5,300lbs total), I went to get off the highway. I realized I wasn't stopping fast and had to two-foot the brake pedal. Trailer got a little squirly but I managed to stay on the road and keep my truck in one piece, or so I thought. I saw smoke billowing from the truck, I figured I just smoked a brake pad. Pulled into the gas station and found the driver front wheel well covered in coolant, and the coolant had saturated my brake caliper, explaining my hard braking. I popped the hood and the coolant level was low, opened the degas bottle and there was a ton of pressure behind it. From June till now there was barely if any pressure behind that cap and it is a new bottle with the max line where the old min line was so it's never been overfilled per the TSB. EGR system was removed before the HG job, running a coolant filter, and I don't see more than a 9 degree delta between ECT and EOT even when towing. I was going to replace the T-stat today because it was running cold for my liking, 172 in 25 degree weather and unknown if it was ever changed before. During the summer I was running Eric's Xtreme street tune, always being sure to change that tune for his tow tune even if I was hauling my little 14' boat, and never romping on it. Any ideas? I'm just hoping the tech didn't put 245 lb-ft on the studs and I need to retorque... The irony is I'm doing a cab-off stud install on my friend's truck tomorrow.. Mine might be next!
