Do you want to fit a new one or a second hand one?
A new one will need new cam bearings that will have to be reamed to fit.
On the other hand I just happen to have a suitable second hand cam shaft in the workshop.
There is a fair amount of work. You will have to remove the head to get the cam followers out (they come up thru the push rods holes) and you'll have to remove all the timing gear and radiator to extract the cam shaft out of the front of the block.
I would also be interested in finding out why the camshaft snapped. There maybe more damage than just the camshaft.

Well im told its a camshaft ? Apparently when you put the pushrod's in one just drops down like the follower's fallen out or the camshaft snapped ? Again i no nothing about these engines this is my first discovery ! I should get it to my workshop this week then i can start the diagnosis from the begining. Interested in the 2nd hand cam whats the damage ? My workshops in Bartley so not to far away !
A CAMSHAFT snapping is EXTREMELY unusual, and even if it did, in a 200tdi the followers can't readily drop out - unless the camshaft disintegrated and parts of it actually fell out from between the bearings. I don't think so.
You take it home, and YOU take off the rocker cover, and YOU have a good look at the situation.
If it was mine, I would whip out either the glow plugs or the injectors, then very carefully turn the engine over (the right direction only!) by the crankshaft pulley nut while watching the rockers and valves. It would be quite possible to do this without taking out plugs or injectors, just a little more difficult to turn. In two full turns of the engine you will know for sure if the camshaft is broken or not.
If NONE of the rockers rock - suspect a snapped cambelt and 5 or 6 bent pushrods.
If you spot that each rocker rocks, the camshaft is not bust and neither is the cambelt.
If SOME rockers rock, but some do not, it will be the ones nearer the front of the engine which do, and this would suggest a clean break in the camshaft. You CAN change the camshaft WITHOUT taking the head off, and you do NOT need to take the engine out either, but it's a good trick, and would be difficult if the camshaft was snapped.
Next you want to make sure that one or more rockers does NOT have grossly excess clearance, which might suggest a collapsed cam follower or a buckled pushrod.
Most people on this forum would risk a fiver that the camshaft is NOT broken!
Please report your findings when you get in among it!

I agree with CharlesY that a broken cam belt is more likely; altho' I am apt to take people at there word . However a close inspection is definately good idea.
@Rogers5018 If you do find out that it is camshaft or followers or even pushrods then let me know as I have second hand items on the shelf here.

Thanks for your help i'll be surprised if it is a camshaft i've been a mechanic for 11 years and have only seen 2 snapped ! I will report all my findings (andyb66,charlesy) Cheers again !
Well hurry up about it!
We are all dying to find out what the F*** is wrong with the thing.
If you weren't about 500 miles away I would come and look personally!
I still bet the camshaft is in one piece.
Bust Belt and mangled pushrods ... that's my best bet.

Tuesday i should find out with a bit of luck ! i'll keep you posted !
I agree with charlie, if the cam snapped it would still be there but probably not turning depending on where it broke. If a cam follower broke up the pushrod would drop onto the cam as you say, however a cam that worn would have been obvious some time ago, noise, missfire and loss of power.
I think he bought this Landy as a non-runner, and if the rest of it is in good nick he's probably made a good buy.
Even if he needs to whip out the engine, it's no huge deal to sort one of these engines, and none of the bits are expensive. He could find a 2.5NA somewhere almost for nothing, and steal the camshaft, cam followers, pushrods, all of which I THINK are the same as the 200tdi.
Pushrods ... are they about £3 each? Who cares? Buy eight!
I REALLY REALLY want to know what is wrong with this motor!

Sorry for the delay been a busy couple of weeks. I did buy this as a non runner ! The trucks in my garage now. Looked down on the head no2 inlet follower missing. Took the head off. The carrier for the follower has sheared the securing bolt shot upwards and the follower is missing (in the sump i guess) Turned the engine over camshaft in good condition well happy with that. Is this a common problem ? Anyone no the common cause of this problem or is it just wear and tear ?
I would say this is VERY unusual!
I cannot see how a cam-follower could come UP, and then escape down into the sump. Where is there a space big enough for it to drop down through? There are only the eight pushrod holes, and the oil drains. Are the oil drains big enough to allow a cam-follower through?
Was there a PUSHROD in place for number two inlet valve? If not, where is it? Is it in the sump - mangled?
I think it is more likely the the follower has somehow broken up. I suspect this can happen when the roller comes adrift, which can make the follower be driven UP enough to shear the retainer bolt tip, then the follower can TURN and when the camlobe hits it the follower would disintegrate and the bits could have fallen DOWN past the cam and into the sump.
I would love to conduct a search of the sump-pan!
Keep us informed, but if it was mine I would be taking the sump off and finding ALL the bits that are missing.
It's why we have LandRovers. People with slitties don't get this fun.

I brought the discovery with the valve train off and push-rods out ! The push rod is ok but like i say the carrier sheared that securing bolt i then assume the roller got spat into the sump by the cam then the cam ate the actual follower ! I will remove the sump tomorrow and report on my findings ! Ant suggestions on where to get my parts from with a resonable price ?
Paddocks.
They should be able to supply everything needed.
Failing that a scrapper engine would be a good bet.
I think I would take the camshaft out for a very close look, and find ALL the lost bits!
