Xantia Head gasket?
New to Citroen. Picked up an old MOT'd Xantia 1.9 D with suspected head gasket failure for next to nothing. It is a 93 in excellent condition with full history, worth saving. Before I go to far just want second opinion.
It won't start, turns over but sounds like no compression. Lost power on the motorway, lost all water and died. AA man said it was head gasket, has done 139k so it is due! Had been using a bit of water for a while. Being the non turbo diesel it all looks fairly straightforward to take the head off and see, can really only be the gasket or the head, either way a cheap fix.
Problem is there seems to be no water in the oil or vice versa. seems to be just water getting into combustion chambers.
Is it the head gasket? will I get it checked and skimmed and stick it back on.
Usually a VW person so thanks in advance.

Hi.
If it was on the motorway, there is a VERY good chance then that the HEAD has cooked too, warping to hell, so it will be head off, skim, new gasket and a hop in chance of have a bit of life ...
NON turbo units are easyer to do, as there are no turbo feed and return pipes to dissconnect, just an exhaust. The head WILL come off with exhaust manifoild, but you will need to reach behind to remove the inlet manifold to get at the head bolts..
If you'd like a FULL detailed explanation of the job, let me know and I'll mail you with an how to...
GOOD Luck
Regards

Hi. You would be rather surprised. I've had complete compression loss due to a head gasket and warpped head... Those surfaces have to be PERFECTLY flat I'm sure you know, and also, Gaskett thickness should also be observed too, use a gasskett with 3 notches in it, the thickest one, Regards

It seems unlikely that you would lose all compression due to head gasket failure. Even if the cam belt is intact it could have slipped. Take the rocker cover off and see if the camshaft is in one piece.

If the cylinder head has been really really badly overheated, then the differentail thermal expansion between the head and the head bolts means that the head will actually stretch and permanently deform the bolts. When the head cools down again, the bolts are effectively loose, and there is absolutely naff-all compression available.
I've seen this happen on 2 different engines now. One was a Ford 16v petrol engine, and the other a ZX 1.9TD. Very clear in both cases was the obvious lack of compression on cranking the engine. Neither engine would even think about starting: all they managed to do was pump coolant out of the expansion tank!
If this is what has happened to this engine, then it will undoubtedly need a new set of bolts (best to fit them anyway). Any decent machine shop will be able to tell you if the surface can be machined, or if it's too badly gone. Re-grind the valves, set the clearances and you should be away.
