KHE Posted September 13, 2015 Report Share Posted September 13, 2015 No sealer in a bottle will work to seal a headgasket leak - if in fact you do have a headgasket leak. Do block test on the coolant and a cylinder pressure test to see if exhaust gasses are getting into the coolant.

Logan Posted September 14, 2015 Report Share Posted September 14, 2015 There is a Kent Moore/ TimeSert kit to repair the headbolts. That version of Northstar uses the J-42385-2030 kit. It can be rented.

winterset Posted September 14, 2015 Report Share Posted September 14, 2015 I think it's important to mention is that the N* suffers from pulled head bolts, and generally not a failed gasket. That being said, nothing in a bottle will solve the failure in the head clamping force caused by damaged threads in the bolts. Only thing it'll do is make the repair tougher for the rebuilder who will have to clean this gasket sealer out. Link to comment Share on other sites More sharing options...
