yah the head gasket "fixer" fixed it. cools like normal. im afraid to boost on it, but the bottle literally says good for diesels, and my 3.0 duramax is 40+psi
also, i had kinda forgot it had this problem when if first got it a couple years ago, the sealer worked for like 2 years including like 6 months of 10+psi
so whatever, maybe i'll fix it right this winter. but i do daily this truck so winter is still boosting weather.
i fixed the two bolts that were broken off in the drivers side exhaust manifold / head
my plan actually worked perfectly, i left the manifold on and used the holes as a guide for the drill bit, drilled them out, took manifold off and tapped the holes with 3/8 bolt and it worked great and they tighten up, manifold doesn't leak when cold anymore.
i should've left the manifold on and tapped the bolt holes in the manifold as well as the head, then i could've left the vbands alone... oh wel
the big problem, and why i didn't want to do this for so long, since after a min or two of running the heat would fix the leak... now the vbands are leaking like a bitch and these cheap ones are single use...
i should have two clamps coming monday and then maybe i won't have any exhaust leaks lol
