George really worrying news( having 2xTDV6 in the family with one being in RSA), I have been following on SA 4x4 community, so what you are saying is that the replacement sub assembl( only way to replace piston on a failed TDV6) has been upgraded? You did mention in SA4x4comunity of your "Poly-TFL" treated cars in Europe any suggestion for uk based suppliers seeing my D3 on average is parked for 4/5weeks in Dec every year?
Disco mickey any experience of this type of engine Failure?
As always statitcs % of failures would put this in perspective but I intend to keep my D3 so would like to limit nasty/costly surprises!A few mods... and keeping it all running...Faultmate MSV2

Hi D4JWW
there used to be a distributor for Poly-TFE in the UK. What I would suggest is that you get a few guys together and then we can send you a 1 litre bottle of the Poly-TFE concentrate. That will be enough for 12 engine treatments. You can mix it yourself with the proper oil. That is what TGWInduna does.
The main problem comes with wear and tear. Everytime the engine is started after some time standing (3 days +) there will be an initial dry run until the oil pressure has been built up sufficiently. And it is in that crucial period, that the big end bearings can start to move, provided they have been exposed to sufficient wear and tear.
The Poly-TFE treatment puts an effective stop to this. So it is a longterm solution and not a quick fix. We have some of the vehicles in our fleet that stand for more than 5 months during (european) winter, due to the salt on the roads. For the past 20+ years they have been protected by this method.
One of the best preventative steps you can take is to have an oil analysis done. This will highlight any upcoming problems with bearing related issues, due to hightened bearing material related abrasive particles in the oil.
Good luck!EX AFRICA SEMPER ALIQUID NOVI

Just to be clear hgbosch are you saying that the main journal bearings are rotating or the big end bearings

Hi hgbosch!
" ......Because on the new motors, a coarse cross honing pattern has been introduced on the conrod and lower half bearing block, which will put a stop to this unintentional movement of bearing shells.

Hi all I have a jaguar 2.7 diesel 2005 with 80000 miles on it with full jaguar service history.
In September i got a light tapping noise which got louder and louder but it sounded like a stuck lifter.
I was going to change the oil so i removed the sump only to find bearing material...Oh .
I'm in the process of stripping the engine and have found the 3 of the 4 main bearings are .
The bigends look ok apart from the top bearing showing a very small amount of copper directly inline with the top of the conrod.
If Jaguar/Landrover have altered the block that means that they know that this is a problem, so why don't they help the people like us who have had this happen?
Iv'e been told that you can not get the bearings but it MUST be possible to match bearings after measuring the Con rod / crackshaft Journals and it must be possible to machine the block at an engine shop to accept bearings with a tab on them.
All the best and take care Marc

Hello hgbosch
I have been following this thread for a while and think I should look for this magic muti. My D3 is coming up to 86000km now and just had a service end Jan due to the 6 month interval, not on distance.
I have 2 questions....
I am battling to find Mineral spec Two stroke oil, so would synthetic suffice, and
Question 2 who makes the best POLY TFE in your opinion, and where will I get it in Durban?
Then, my D3 has done about 500km since its service in Jan, of which it was a biggie, R12100.00 worth incl disc and pads. Can I just add to the engine right now or would I need to drain?
Just as far as Slick50 is concerned! I am a pilot by trade and early on when slick50 came into SA, we had an owner put the product into his Cessna 210 turbo Centurion. About 10 flight hrs or so later, during take off at Grand Central Airport he had a catostrophic failure where a piston acctually climbed out of the engine, post fire and an emergency crash landing 200 m off the runway. The engine was sent away and it was determind to be the additive interferring with some other component in the oil system. The aircraft rolled onto its side in the crash, but everyone climbed out fine. Since then I have been sceptical, but I also know that it may be completely unrelated. Your comments if you would be so kind?

Hi HGBosch
Please advise on the where i can get this Poly TFE, im based in Cape Town.
Also the type of 2s0 is thatt sold at all the salsol's?
What top tech spec liquimoly would u recomened, as the guys locally only seem to have 4200 5w30 and not the 4500.
Thanks

Hi
I'm a RRS 05 Owner, running the 2.7 TDV6 Jag engine, does anyone know if this has happened to many of these problems have occurred with this engine??
I know the RRS has many similarities to the D3 so don't want to run the risk as our RRS is our main day to day work horse. We have a extended warranty and service plan and has always been looked after by the LR dealer since we've bought it from them.

Hi Ededdie
sorry for the late reply, you can source Poly-TFE from Nekkies at Gateway Offroad Centre in Wellington and also in CPT.
Here is a pic of the oil I use for the TDV6

Hi Sender
the TDV6 bottom end problems are basically two-fold
1. Bearings start to rotate due to excessive friction during cold starts mainly after prolonged periods of non-activity. The TDV6 needs some time to build up oil pressure...... There is a fix here in South Africa for this. It is called Poly-TFE and all who are using it on their TDV6 engines have been spared from engine failures caused by bearings turning.
2. Snapped cranks - this is mainly caused by a failed or faulty front crank balancer. They are of a two-part rubber bonded design. With age etc, the rubber bonding separates and eventually fails and the balancer starts to wobble. Snapping of cranks has been observed to happen in engines with perfect bearings.
So the only solution here is to change the front balancer every 100'000km or so. Early warning sign are excessive wear on the Poly-V belt on the edge facing the radiator (fraying).
I trust this helps!EX AFRICA SEMPER ALIQUID NOVI

Mechanically the RRS is the same as the D3 so will suffer similar issues.Freelander SE 2005 Auto.

Yep, old style RRS is a d3 in a pretty skirt.
Just don't tell them that on The Dark Side ( www.rrsport.co.uk ), they get upset.

Not just mechanically either.

It's a bit like pointing out to an ePoke owner that their car is basically a freebie 2 in a miniskirt and to a DiscoSport fan that it's really a Freelander 3 with a big angry D I S C O V E R Y badge on its ar$e. Power of badging.

Cylinder 6 Piston Melt
George
I had a cylinder 6 Piston melt on my 07 Disco 3. Read thru this thread as thoroughly has my limited technical skills could afford and to me it seemed that you had an answer to the big end problems but not for the melting of the cylinder 6 piston... other than carbon build up.
My Disco 'blew-up' going up a hill towing a 3 tonne caravan and had been remapped and this happened about 6k after replacing timing belts without the use of a crank locking pin and mis-timing my engine.
My mechanic is telling me to buy a secondhand engine ... I think because other than a leaky injector ( possibly care of re-mapping) he is not sure what the root cause may have been.
So my questions are:
1. What did you conclude the cause of this was? Why Cylinder 6?
2. Am I good to go if I:
a. Replace the piston and clean off carbon from the top end of the motor (heads, valves, piston crowns)
b. Replace injector - cylinder 6 (tolerance check others)
c. Reset cam timing
d. Restore factory engine map/or back off the exisiting one (I am still up in the air on this)
e. Blank EGR's
I really don't want to buy a secondhand engine - I have treated mine well in terms of maintenance intervals and it has spent most of it's life pooddling around central London. I also try to drive it on the torque curve and not just 'flatten' the throttle up hills... although towing a heavy van excessive throttle is always going to occur naturally.
