didn't use Permatex Thread Sealant when installing heads

If I coat anything lower than that on the studs, I fear It will be near impossible to get the heads off in the future. I have never used the sealer and don't know if it sets up like silicone or is more like a thick water resistant grease. I'll see tomorrow when I buy some.
Thanks to your input, now I am not going to torque beyond 40. If I still have leaks, I will try the powder aluminum. My only reason for not going that route first is tube videos tend to swing toward that as a temp fix.



Regards, and thanks for all your input and time.

Randy,
The aluminum sealant enters the cooling system (radiator). It stays in circulation until / unless it finds a leak. If and when it finds a leak, it fills that void.
If it finds no leaks, it stays in circulation.
Please, just do the three heat cycles / re-torque, add the sealer and drive this thing for a bit.
