It sounds to me like oil cooler failure - commonly misdiagnosed as head gasket failure.
But no doubt someone much more knowledgable than me will be able to give you more info!  :y

When you say, just bought it, was it bought as a non runner or have you been sold something dodgy

Almost certainly oil cooler failure. The oil is at higher pressure than the coolant, so when it fails loads of oil gets into the cooling system. Not a huge job (certainly a far easier one than a head gasket) but there is a fair amount of work involved. There is a how-to in the maintenance guides section that you should have a look through. I haven't had to do one myself but quite a few people on here have. They are around £80 I think, and if you're lucky you may be able to flush the oil out of the cooling system. In some cases the radiator is too sludged up and has to be replaced.

BTW I just hope it hadn't been like that too long, as overheating is a distinct possibility due to the poor cooling of oil/water mix!

Rob  your car is in need of some serious servicing and pronto too. i would guess that the cooling system had been drained and flushed  prior to the sale to hide the problem. The oil cooler would not fail big time just like that with that amount of oil in the water. there is always some tell tale signs of pending cooler problems and oil coolers nearly always fail due to lack of servicing and incorrect  coolant mix levels. The head gaskets very rarely fail on the v6 motors, so that is not the place to start the diagnosis.    :(

When you buy from auction you must listen very carefully to the auctioneers description of the car and its condition. By the sound of it the only thing that you can quibble about is that the car has been mis- described, ie not full service history. In my experience the auctioneer will usually say how many stamps are in the service book, all the auctioneer says is normally recorded. Try and get something back, good luck, but don't hold your breath.

Rob,

While this all sounds like you've been done (depending on what you paid of course), its not the end of the world.

But you do need to plan on doing the oil cooler (don't try to drive it as is) and a new cambelt/water pump asap.
Plenty of help/advice on here if you tackle it yourself :y

Cheers,

Ian

Thanks again all , contacted auction house today B.C.A told them they said it had FSH (was actually due 6 months ago) tried to get my point accross saying that a FSH is yearly or 20,ooo miles whichever comes first , also managed to track down a garage who looked at this vehicle for previous owner 4 weeks ago and advised him that the r/h head gasket was gone and gave him the costs which he wouldnt pay . So someone has knew what they were doing ,flushed the water tank , and put fresh oil in then took it to auction !!! thare are some unscrupulous people out there >:( . Have been in touch with trading standards and they say I have a case in being sold an unroadworthy vehicle , so I am looking into that area , have also had my mechanic take a look and furnished him with all your info , he's holding off doing anything until next week , have ordered head gaskets, bolts, water/oil pumps and timing belt kit just in case , thanks again everyone , will keep you informed, Rob

hope you can return the head gaskets and bolts as almost certainly not needed.

How much did you pay may we ask?  It may be you still have a decent buy, but just needs sorting out.
Still pursue them for compensation though :y
