Gasket???

Hi

I have been having a few issues with my discovery and think I am now left with it being the Gasket.

As I drove away from a friends house he noticed I left a large patch of oil on the pavement. Hadnt happened at home, would have noticed just laid a new drive. Upon looking the header tank was full of thick black oil, so checked around and oil cooler was the culprit. I changed the oil cooler and flushed the system through with biological washing powder as advised, then several times with clean water.
Did a 60 journey and everything was fine no running problems at all. The next day started the return 60 mile journey and not even 10 mile in to it she overheated, went up exrememly quickly to point that as i finally managed to pull over cut out. There was no water left in the system so waited for engine to cool, filled up with water and crawled home at 50mph on the motorway which she handled fine until a mile from home and we hit traffic. After sitting in it for a while lost all power and had to wait to cool and re fill again. Once home i changed the thermostat in case that was clogged have again flushed eveything through, but cant stop the over heating, and there seems an incredible amount of pressure in the system and the water doesnt seem to be getting to the radiator as its not getting hot nor are the pipes off the thermostat.
Head gasket seems to be the option now, but could someone please offer any advice. I have tried to complete all the work on the car myself, trying to learn as i go, this foroum has been incredibly useful, so turning to you for help now.

Cheers

Petrol / diesel ??
200tdi / 300tdi / Td5 / Tdv6 ??
3.5 v8 / 3.9 v8 ??

Water pump ?

Its a TD5 diesel. Update so far is I removed the head and took it to the engineers, who had to do quite a big skim, as it was pretty warped. Hopefulyl get it back tomorrow and begin the process of rebuild hoping to find the problems resolved. Fingers crossed, Ill let you know how it goes, and thanks for your replies

how much did they take off ?

make sure when it gets refitted you use metal dowels instead of plastic to re-align it

Make sure they recut and seated the valves to take account of the skimming. If not you may get away with the thickest head gasket but it depends on how much they took off the head. If not you will get valve to piston contact which is a tad inconvenient not to mention expensive.
