sorry to disagree but I would have gone for sticking valves. The 2litre T series can suffer from this, even if it has been looked after, besides which if the head was cracked or the head gasket gone it would have showed up on the compression test.
An engine flush may help, as would running it on diesel oil for 1000 miles and then change it, at least that is what my dad did with his 820 with the same engine and cured it for a good 15,000miles and had very similar problems to what you describe.
May be worth popping over to www.mg-rover.org and post in their technical section and asking the question there as well.

Many thanks for your suggestions. As an update, I took it along today to a chap at a Rover service garage I managed to find & he lifted each lead in turn with the engine running-numbers 3 & 4 went clack clack as they should but 2 & 1 were very much quieter. The car still drives to over 70 but is drinking fuel like anything.

Could it be a collapsed Catalitic Converter?

I do like my Diesels to be Turbocharged for that extra OOMPH!!!!

How can I tell if it's collapsed?

according to autodata the map sensor is built into the ecm check that the hose to this isnt blocked (carefully as the maps are sensitive)

Steve, went from bottom to mid gauge within 3 miles & stayed there

Does it have to be diesel oil or maybe a much lighter ordinary oil? Will this unstick the valves, presumably in 1 & 2 cylinders? Also getting suggestions in mg-rover as you suggested!
|
Could it be the coil pack ? (or its connections).
|

Seems it may well be sticking valves.
Do you mean drain the engine oil & refill with diesel fuel directly into the engine instead of ordinary engine oil?
Not getting much out of mg-rover site!
|
While having no suggestion for curing this, I am not sure bbroollea was suggesting filling the sump with diesel! Perhaps by diesel oil, an oil suitable for diesel engines was meant?

Am desperately trying to find out exactly what he did mean but can't get a response!!

Diesel engine oil is what is meant-not fuel oil-It does on some engines work ok but not all..ie a stripdown is required depends how sticky the valve/s are
