Head Gasket Seeping Above Serial Number

[J Franklin]

Add some powdered stop leak like Alumaseal or such. It will not clog the radiator if you follow the label and will stop the seep. But do check the head bolt torque.

Thanks for the replies. I just wasn’t sure if this was something that can seep for 20 years without incident or if it was a leak for a week then completely blow kind of thing. Either way, I’d run it until it blew before I’d replace it.
