1.5d head gasket

I presume that this engine {1.5 diesel} is the same whether fitted to the
106 Peugeot or the Citroen AX, so can anyone offer any advice on the
following::-

My AX had to have a new gasket at 50k when the oil gallery joint began
leaking badly, blowing oil over the fan belt, timing belt etc. At 101k now,
and the engine has started to sporadically throw out a pint or so of coolant
on some occasions. Inspection of the expansion tank when the engine is
started from cold reveals a series of small bubbles accompanied by a small
amount of, what looks like, steam. Even when cold, the coolant is under
pressure as this can be felt when removing expansion tank cap.

I am assuming that the head gasket has failed, but would be interested to
hear any comments/observations as to whether this is a common failing with
these engines and can I expect it to go again in another 50k?

The head wasn't skimmed for the oil leak but the garage reckons to do this
for all head gasket/coolant failures.

Yes, it is quite common. All the symptoms point to head gasket. I
should get the head cracked tested, and if all well, then skimmed.
Always renew the timing belt and alternator belt if cracked. Check the
water pump for leakage and renew the thermostat.
