I would try it with no thermostat in, but it's unlikely that's the problem. You might have a head gasket leaking a small amount.
Les.
Thanks Les.
I removed the innards of the thermostat and re-installed the outter ring and rubber ring.
The fact that there is a small of amount of water dissappearing when I do short distances, but no loss on the open road, 150 km trips or more, sort of gives me the uncomfortable feeling the head gasket is giving notice.
No water in the oil, but it may be a combustion chamber leak?

Driving home from work, my Discovery's engine temepature shot up to the red. I pulled over and found the expansion tank full to the top, and cold, so was the top radiator hose and the thin pipes to the expansion tank. Opened the bleed screws, and with a blurp the water was sucked back into the system, the temperature went back to normal, and all was well. As a precaution I replaced the thermostat with a new original one. Had no problem bleeding the system, and all went well, untill I opened the expansion tank, a week later, on a cold engine. I topped up to the top of the marker, closed the tank and started my trip to work, halfway (3km), same happened again. Bleed the system and back to normal.This now repeated itself 4 times, I replaced all old hoses, but no luck.
This one really has me bogged down, can the second thermostat be the culprit?

"As a precaution I did a cold, dry compression test and the values were 12,4 12,4 11,5 11,5 kg/cm². I am happy with that"
Should he be?
Jim, knowing the high comprerssion ratios of a diesel, I presume the compression test is best done with na compression meter that has to be clamped in position, otherwise I must make an appointment with you and have a proper test done.
-
Judging by the values themselfs, he shouldn't. These are petrol engine values, more like 8-9 compression ratio engine. I think there's a reading error, wrong scale, math error or something. Otherwise I don't think that 300tdi would start from cold.
Judging by the difference between cylinders, it's acceptable. There's an 8% difference, not great but still under the lowest limit of 10%.
I forgot to mention that the compression tester was a cheapy. I had to push the end into the opening by hand, was more intersted in the deviation between the readings. Since there is now loss of power, and she stars easy, I am still not to upset.

The final on my Tdi's new injectors:
A sound as sweet as music when I fired up my Tdi with the new injectors, the diesel clatter as discreet as royalty in public, no smoke billowing out of the exhaust, and the power on the road as smooth as only a turbo diesel can be.
As a precaution I did a cold, dry compression test and the values were 12,4 12,4 11,5 11,5 kg/cm². I am happy with that, and the engine's oil consumption is negligible.
Why would two injectors fail on an engine with 183 000 km on the odo? I have two possibilities:
1 The sock, jamming the no 2 inlet valve partially open, and then snapping the rocker shaft, may have resulted in crazy mixtures in no 2 & 3 cylinders, with the engine idling and doing three trips round the block.
2 When I collected my Tdi, the previous owner informed me that one injector blocked, and he had all four replaced with new injectors. The LR specialist invoiced him for 4 new injectors. This was one year ago, 10 300 km later. Looking at the condition of the injectors, I am certain that they were not new, probably cleaned, or replaced with second hand injectors. Two of the brass washers were also installed the wrong way around.
Any way, I replaced them with new ones, and now have the confidence that the installation is done correctly.

And your point is ?? they could have been where your "local lr parts supplier" bought them from, is he not allowed to earn a living, like you are !!
Your "local lr parts supplier" may not sell many of the air bags for disco 2, whereas Paddocks sell loads, hence the cost of stocking, You would be the first to complain, when your "local lr parts supplier" closed down, due to lack of return on capital !!
Also i presume your "local lr parts supplier" and your "unknowing dad" are in Ireland,, whereas Paddocks are in the UK ?? hardly next door then,
Ouch! I read some knuckle wrapping here.
I also belive in the right to earn a living, but in my case, a 400% differene in price, someboby is making a real killing.

Well the journey to Billing and back was very interesting, which equated to approximately 7½ hours of white knuckle ride!?!?!
It appears that I am suffering with a Violent Front Wheel Shake between 38 - 50 mph, it is fine below that speed and fine above that speed and only happens when the vehicle is under load i.e. Decelerating within that range is okay?!?!?!
I am running 35x12.50x15 BFG Muds on Mach 5 Bead locking Rims within each tyre I have approximately 15ozs of Airsoft BB’s in order to balance them from the inside out (see this link http://4x4trailhunters.com/article.php?id=18 for more info)
I have an amount of play in my front nearside CV Housing, but have been told that this shouldn’t cause any grief, but will be removing a shim or two shortly in order to hopefully resolve this issue!?!?!? :
My Panhard Rod Bushes are fine!?!?!
Any ideas as to what it could be would be gratefully received?!?!?! B)
I had all the above frustations, and in the end the following was found:
1. Both front steel rims and the tyres had a small out of round error. Wheels were balanced by rotating the tyre on the rim untill the lowest out-of-balance reading was achieved, and then the wheels were balanced. The problem improvrd, but did not go away.
The second test was the backlash on the PS control arm, I noted a small play in the straight ahead position, did a small adjustment and the shakes disappeared.

First set or the replacements?
Hav'nt the foggiest idea, will wait and see if more mail arrives from the UK.

After my sock experience, and the subsequint repairs, my Discovry really ran like clockwork. however I noted an ever increasing plume of grey/black smoke when idling, and an ever increasing plume of black smoke when she works hard.
The final came on Sunday when exiting the freeway, she made some loud knocking noise and lost power. I nursed her home, and checked the valve movement, valve clearances, everythins was to spec. Then started the engine and cheked the injectors, found number 2 blocked.
I then removed all four and found them nearly as bad. The previous owner was charged for replacing the injectors, less than a year ago. 10000km later, and the injectors were really shot. The repair expert cleaned the injectors, and charged for new ones.
Got the Bosch injectors from non steales at a quarter of the price.

At 12:45 RSA time, on the day of 12 February 2008, I received a white envelope per avion, and inside I found my two Form stickers.
Thanks Les!
I will post a photo once my Discovery is running again.

oooooh, do I get a sticker then?
I have lost so much stuff in the post to SA that I normally try to get things sent to a UK address and get someone to bring it in their luggage.
When I bought a G10 watch from Anchor Supplies, I had it sent to France and a relation brought it here.
It seems to be incoming post that gets stolen, as I have sent lots of RAVE CDs and whatever the other way.
Jim, let's wait and see how many stickers I receive...............................
-
I sent another about 5-7 days ago Thys.
Les.
Thanks Les,
If, due to my impatience, more than one set arrives, I will pass them on to Jim Atrill, there may be local Forum Members interested in the stickers.
-
Go on Les. Perhaps he wants some free slippers from The Mail on Sunday, decorative china plates or non ironing trousers
No no, I desperately need socks, as my engine swallowed my last pair..........
-
hands up who thinks Thys should have PM'd Les in the first place and this is wasted database storage
Hey, I gave up on trying to PM, as the PM's success rate is not very high. -
You don't seriously want me to post your address on here for all to see do you Thys?
I don't know how long post takes to get to South Africa, but I would imagine 10-days or more.
Les.
Les, Please PM the info to me, and if my memory serves me correctly, we are now running into 3 weeks. I have not given up yet, that is why I need to check on my side of the postal system. -
Help! My Forum Stickers has not reached me. They must be missing in action, or went A.W.O.L. To what adress were they mailed, and on what date? This willl help me to trace the local Post office.
-
As I said, all's well that ends well, but just to remind me not to something socking stupid again; look at the Discovery's left rear pillar......

Hi all , can anyone advise on when I should next change the timing belt on a 97 300TDi auto.
Changed it at 66k Miles (no yellow square so assuming they didn't fit the revised pulley kit) and its now at 118K, so current belts done 52K miles).
Many Thanks - Jason
Remember my sock episode................................
-
I'll send you some more this week Thys - don't worry.
Les.
Les, thanks for your diligence, will watch the mail.

I think someone is systematically removing aspects of your life to gain access to your stickers, Ok, but what happend to my stickers?
-
I replied to your pm last night Thys
Les.
Thanks Les,
I think something is not working on my side, my sent messages shows that none was read, I did activate the tracking option, and my inbox is empty. Any help on how to fix this?

Can someone please help me, I ordered 2 forum stickers, paid by PayPal, PM'ed the sticker chap, Les, and the money chap, White90, but cannot get any response from them?
Desperate forum sticker wannabee.

Careful. That could make you toes all day. All's well that ends well then, Sockmeister?
Oh yeh! I nade up many excuses to drive around town today, just for the enjoyment of being back in my Disco!

I bet you feel a real heel now.
The final part of my socking story was a bill of R 3674.47c; replace a broken rocker shaft, re-set the timing...........
But my pain in all, what a relief and delight to drive her again, my wife was threatening to force feed me Prozac, but now all is well in all departments.....

Engine cooling problems 300 Tdi

Les,
I know with a petrol engine, the radiator specialists mounts transparent pipe on the radiator fill point, and fills it with a liquid that changes colour if combustion products are present. This is done with the engine running. Can this be done with the Land Rover Tdi engine as well, or can they do some kind of pressure test?
