Re: Cylinder head?

Just a thought 39 . . . Seems strange the coolant pooling around the plug, as a tight plug with a decent (spark plug) washer I would have thought would be an 'airtight' seal. If not I guess pressure is high enough to be pushing steam past and this is condensing there to form a puddle.

Others are most probably right about blown head gasket, however here is a thought . . . .

I wonder how close the water jacket comes to the spark plug hole. Is it possible the head has cracked or corroded through between the plug hole / plug recess and the water jacket (which is allowing the coolant through)? Of course there might be a 'mile' of iron between the jacket and the plug, but I'd suggest checking for cracks anyway. Not much fun getting it all back together to find that you have a cracked (or possibly warped) head.
