It was a payen head gasket (I think I've been calling it permatex, but
meant payen).  It has metal rings round the cylinders and should be a
high quality one.  I paid extra for it and swapped out the standard one
in the decoke set.  It came from TRGB.

I'm going to pull the head in a bit and hoping that it is either a gasket
failure or that the head nuts have loosened themselves. If this is the
case I will order a new gasket along with new cylinder head studs, nuts
and washers.  I presume that the old studs can be easily removed with the
double nut technique?

I will also take care to re-torque the head once the engine is up to
temperature, should I loosen teh nuts a 1/4 turn and then retorque, or
just retorque straight away?

Also when tightening initally I was tightening each nut by a quater turn
at a time as recommended in haynes, should I tighten by smaller
increments than this?

cheers
John
