need help with cooling system, and OH MY GOD

[Alan Pritchard]

Well, there is a tiny amount of water in the oil, no oil in the water. It
does build up serious pressure, when at idle last night, the occasional
stumble produced a quick hiss from the header tank.
Swapping the head is logical, but, ive taken the manifolds off i5 + I4's
before, and know what a pita it is, also I have only the 2.2 bottom end (kv)
while my spare engine (with head removed) is an NG thru and thru.

It may simply be a blown head gasket.  Much simpler than replacing the
entire engine.  I'd at least check the compression first.  Well.  that
wouldn't distinguish between a warped head and a blown gasket would it?  But
it would tell you if something is wrong in that area.  Check for signs of
cross-contamination of coolant and oil.  Oil in the coolant or coolant in
the oil is BAD.  Also, when you take off the coolant "overflow tank cap" is
there a lot of pressure inside?

Ok, update:
Took the thermostat out in the hope it had jammed.
2 mile round trip the car lost 1.5 litres of water, through overpressure in
the header tank.
I suspect I have warped the head due to me stupidly running low on water.
And as I have a spare engine, I figure its just as easy to change the whole
engine rather than just the head.
Any btdts for changing an engine on typ 89's?
