I can see air bubbles coming out of the top tube of his cool head. After a while, the cap pressurises and spews coolant out. Did He blow a head gasket? He ran 93 oct and it was backing out the plugs. It was definately predetonating. Any help apreciated. We are in glamis now!

Yep, you have a blown head gasket. The combustion pressure will pressurize the cooling system. You must fix that first! As far as the detonation goes, you need to first verify the jetting isn't lean. Then try backing off the timing or running higher octane fuel.

Head gasket if he's got a stock head, Oring if he's got an aftermarket head.

See it all the time...if you're lucky, it just runs like poo and pops the ring.

But it can very easily do more damage.

 

Pull the head after you drain the coolant.
