Hey folks. I wanted to give an update on my 04 GXP with the blown head gasket. I was not financially able to swap the motor with a rebuilt one. Prices ranged between 7k and 12k. Found some off the shelf head gasket sealer products but none seemed to have any good reviews or resulted in a long term fix. After googling “northstar head gasket problem” I discovered a product called THERMALWELD. It was more than twice the price of any of the off the shelf head gasket sealer products and couldn’t find any online reviews of the product. The car is a cream puff and only had 123k miles. I couldn’t in all good conscience let it end up in a junkyard. So I pulled the trigger and spent the $250 bucks. The company rep Mr Hooper walked me through the treatment process and within 5 minutes the coolant stopped pouring out of the exhaust. I’m a believer! The stuff worked! 6+ months later and I’m still using it as my daily driver. It’s a miracle!

That is a miracle. Cool to see it work out.

Update on my 04 GXP:
Still running, not using coolant at 134k+ mileage. Definitely worth the $250 I spent to fix the leaking head gasket! The only issue at the moment are lean codes on banks 1&2 which is throwing a chk eng code.

Nice. You certainly got your money back out of that repair.
