Disco 200TDI overheat/radiator problem, help please!!!

Shifting Up
I have just purchased a 1992 Discovery with 250,000 kilometers on it. After driving it for an hour or so, i noticed the heat gauge needle was nearing the red. When i returned home i checked the coolant and there was none in there. But when ever i fill it up and turn the engine on, it bubbles out of the radiator overflow bottle cap. There is no cracks or anything that is visually wrong with the overflow bottle or cap, and i noticed that the cap seems too have 2 valves on it (one in, one out) which seem too be where the coolant is coming out of.
It does this almost as soon as the engine is turned on (even when engine is cool) and more so when i rev up the engine.

Note that it never actually seems too overheat (needle never gets all the way too the red and overheat light never comes on) only gets very hot?
I do not know too much about engines but the only thing i could think of is that the valve on the bottle cap is old and the spring controlling the valve is tired.
Also, i live in australia so the ambient temperature is higher than you UK people.

Does anybody know the cause of this problem and how to cure it?

Thanks, Luke.
 
hmm, couldnt see the edit button....

also i would like too add that the coolant that bubbles out of the radiator overflow is cool (as i had it spurt onto me when my friend turned the car on) and i left the car on for a good 5 minutes and it still seems too be cool enough too touch.
 
The 2 valves are to let pressure out and let air back in, so the hoses don't collapse.

If it pumps bubbles out when it's cold, there is Gas getting into the system from the combustion chamber. Does it misfire or run on 3 cylinders? If it bubbles continuosly from cold and can blow a stream of water, the Head Gasket has gone in a big way or you have a cracked head.

It doesn't appear too misfire, but i think there is a slight loss of power. How do i tell if it is running on 3 cyclinders?
There is also rather abit of smoke that comes out when it is cold and warm/hot. The smoke is NOT at all black, but rather white-ish.

And yes it pumps bubbles/water out when it is cold and also pushes it out of the radiator overflow bottle's cap. When i rev up the engine it pushes all most all of the water out of the radiator overflow bottle. After it has done this when i refill the bottle, it seems too drain back into the radiator so i presume it is also emptying the actual radiator.

Last night i was driving it just a little and i noticed it getting hot, so i stopped and there was a Black oil looking liquid coming out of the radiator overflow bottle. The car did not show that it was overheating, although it was near the red mark.

1)The white-ish smoke is probably steam.

2)Pumping water out as described is cylinder compression entering the cooling system.

3)Black oil looking liquid is oil,in the coolant.
I expect you'll find water in the oil,too

Symptoms of head gasket failure and/or serious cracking of the block and/or cylinder head.
As Templar said.

Either way,it's bad news.Hope you have some kind of warranty.

Regards,
Nick.
 
Hmmm, no warranty. Although i did buy it from a dealer and it is less than 100kilometers old from the 2 days ago i bought it.

Does anyone know how much is estimated for the head gaskets/new cyclinder head block things cost? (just for the parts not including labour)

Second land rover and already major problems, I also have a freelander which has lots of small things go wrong continuously, and for that fact i am selling the freelander now. Was hoping my second landrover would be alright but i guess not.

Thanks for your help and quick responses anyway. Luke. =(
 
Recommend you take it back.
This sort of fault does not normally happen all at once,rather,it developes.
I would think it was known of,or at the very least,suspected before you bought the car.
Head gasket replacement is not cheap,a cracked cylinder head is expensive.

Head gasket failure on a 200TDi at that age is not uncommon,I think.

Re your experience with Land Rover,they are a more complex vehicle than most and so need
more care and maintainance,looked after properly,they are normally reliable

Nick.
 
Hmm, the problem is that i can't take it back. I have already talked too him and he has made it clear that there is no warranty and thus he wont be able too return the money, although he told me he has a good mechanic =/ but then again, so do i...

Last resort will be too get it repaired and sue him for the money.......... Although i am under 18 and don't have much money too spare for a lawyer or anything like that =(
 
Yup its the same here, but hes claiming it WAS sold in roadworthy condition, and broke in the 30 minutes after i bought it....
I have found a couple of technicalities though, as by law he has too give me a road worthy cert (pink slip) when i purchase it, he also has too give me a 'Form 8', which i didnt get either.

Grrr, looks like this one is going too court.....
