No Pressure

[Gigsy]

Hi

I have a 98 XM 2.5td. I have been loosing water with no visble leaks and have now been told that the head gasket has gone although there is no water in the oil. I was wondering if anyone could tell me why there should be no pressure in the expansion tank. I can remove the cap when the engine is still at running temp and not even a hiss, nothing.

The head gasket is the probable cause. However, when my car lost water, the head gasket was ok. The cause was a crack in one of the valve guides allowing water to be turned to vapor. This was accompannied by poor starting and running when cold

Thanks Tom, I'm pretty sure that the head gasket is gone as i took it to a coolant specialist who tested it using the blue/yellow dye and i also have no acceleration whatsoever for a 2.5td. Although it starts ok and there is no smoke or water in the oil and i thought at least one of these would be showing. Anyway as I'm now living in Poland and no-one wants to do the job I'm going to try and fix it using Thermagasket from the good ol' US of A. Wish me luck.
