[Vwdiesel] What? Head Gasket Okay!?

[William Longyard]

Yes James, I was going up a long grade in top gear, 70mph.  Now that I 
examine the head closely, it looks like there's a crack between the intake 
and exhaust valves on the no. 2 cylinder.  The edge of the piston is melted 
somewhat.

I need a head, I think, and a 1.6 na piston, I know.
