blown head-gasket or blown engine?

Crikey - that's an old model. On EFI cars the pump circulates fuel continuously. Although it won't with the engine stopped.

EFI has nothing to do with vapor lock. I had a vapor lock on my E12 530i with L-Jetronic EFI. Youse guys in the UK don't know what hot is, and see much fewer conditions that can lead to vapor lock. ;-)

Heh heh, but I do. My Rover EFI (with the Buick donk) suffers from fuel evaporation badly if parked up for a short time after getting hot on a hot day. Didn't used to with leaded petrol. However, it's easily sorted. If I put the gear selector in drive and turn the key the starter doesn't operate but the fuel pump runs. Circulating it around for a short time cools everything down and away it goes.
That same engine on carbs with a mechanical pump was a nightmare for fuel evaporation - even in the UK.

No, but we remember the first Renault 5 Gt Turbo, that had a carb sitting about 3 inches above the turbo charger...
I don't think I need to spell out what happened if you parked up and nipped into the shop for a packet of smokes. :o)
Dodgy.

Freebase, Maybe we should go back to the beginning. Why do you think you have coolant coming out of your exaust. Does your car emit huge clouds of white smoke after being started in the morning? That's what would happen if you are leaking enough coolant into the engine cylinders to cause a hydraulic lock. Or do you just see water dripping out of your exaust pipe when the car is running? This is perfecly normal.

Do a compression and leakdown test on the engine before you spend the time and money to tear it apart.

Bfd's experience is what scares me about these so -called 'specialists' ,, I've already been hosed for $2600 and ain't gonna take it any more..I wish I'd known about this newsgroup a year ago...anyway... when you suggest the compression and leakdown, can either or both combined indicate with some certainty whether it's the head gasket or a cracked block?

No, they both just indicate leakage into or out of the combustion chamber. Once you know that you have to disassemble to find where the actual leakage is occurring. But if you just had the block repaired not that long ago a new head gasket should have gone on there then. Assuming they did a good job that would make the head gasket less likely.
OTOH, if they did a sloppy job or did not properly plane the mating surfaces (if they were chewed up at all) it might mean it is more likely. Always suspect the MRFWU (Most Recently F***ed With Unit)
