Head Bolts Without Sealant
Posted: Sun Jul 12, 2020 9:08 am
When we installed the head after doing some valve work, I pretty much followed the TM except I used copper spray on the mtal side of the head gasket
and Permatex anti-seize on the threads of the head bolts then torqued to 70 ft lbs.
We have not seen any coolant leaks after running it.
After reading some old pots here and on other sites, there is lot of talk about putting sealant on the thread that go into the water jacket.
Also I came across several posts that were negative about using anti-seize on head bolts.
Is sealant critical? I could pull each bolt, one at time, place sealant on it and put it back if needed I guess. I'm wondering if the anti-seize
acted as a sealant.
Thanks
