They are very prone to head gasket failure, and the LPG kits not quite fuelling right.

Hows the coolant system? Does the water sit stable in the bottle before and after cool down? Whats the temp guage say? Will it sit and tick over for 30 minutes without over heating?

Other than that it might have a sticking valve (not a common fault but these things happen)

You could carry out some further pressure tests to pin down the fault.

Good luck Mate

Thank you very much for the info im hoping its a valve sticking! planning on taking the engine out n stripping it to see whats going on n prob sent it to the local engine specialist ! Flushed and changed the coolant last week and it seems to be running better mabey take the radiator out n give it a proper good clean while the engine is out !

Why not just pressure test it with the engine in?

Modify a spark plug to fit your compressors blow gun with a gauge robbed off a foot pump or something, then turn the engine to the various points where the valves should be closed and blow air in, listen down the inlet manifold and down the exhaust for the big leak on the pot that has low compression.

The other trick is to chuck some oil down the pot, if the compression comes up good then it's probably the rings that are gone.
