Thoughts on the TDV6?

[Anderzander]

I’d not seen this channel before … it’s excellent.

What I’ve never seen though is how frequently these occur - but that may just be because I’ve not known any people with a tdv6, rather than there being tons of people out there without issue.

They made an Ineos video too:

You really want the TDV8 - don't waste your cash on the puney V6

I think everyone would wholeheartedly agree. Just a real shame the TDV8 wasn't offered in the D3/4 and some of the other vehicles.

I've become quite addicted to it. The explainations of the failings are really good

 

Having worked on a few D3's and seen the issues with our work D4's, I've always shied away from them. Now I know that gut feeling was worth listening to

[Gazzar]

It's such a shame as they are very nice vehicles when running right. And very good looking I think.

[Gazzar]

Assuming one bought a d4, and the engine was fine, what could one do to improve the reliability, aside from using the better oil? Intensive preventive maintenance?

Would it be possible to increase the flow and pressure to the center bearings? Assuming that taking the engine out was an option, 2 post lift etc. Could the centre bearing oil ways be widened?

I'm just speculating, I don't think I could ever afford to risk buying one of these.

Why not - I have owned my 2007 RRS for 13 years, no issues, great driver and the most reliable vehicle I have ever owned in 55 years of vehicle ownership.

I've a perfectly good Volvo that's barely run in that meets all our driving needs. I'm doing very low miles at the moment, and that's not likely to change much. Not bought fuel since September!!

So the idea of putting the financial equivalent of a decent series one (or a new TIG set and a 2 post lift) into a disco doesn't stack up at the moment. 

 

Don't get me wrong, I'd really like one, they're one of the best looking vehicles on the road, but it doesn't just add up at the moment.

I have a Suzuki Grand Vitara as a run about/works vehicle - like all it's brand, boringly reliable, well thought out and very economic. I keep the Disco for the pleasure of driving and for it's all round usefullness. Yet having driven a fair few D3/4, I am often tempted. I'm only thirty or so vidoes into the 106 done by LR Time and I know for a fact I won't be buying a D3/4, ever. Not even the V8 petrol. Simply mo point. THe 'reliable ' ones are just too uncommon, the standard of LR dealer servicing is poor and the parts cost is ludicrous.  As for the RRS, it's a D3 with a less funbctional body. 

I would have a D2. Very much so, with a TD5 lump. I like them. It's know and it's simple. I like simple. 

Mind you, there have been a few 'you want the TDV8' comments. Just wait until you find out all the problems with those

The TDV8 is in general excellent. Some 3.6's have suffered turbo failures which for some reason was more common in the RRS. I know of a large number of cars well over 100k and none have has this issue. All I have have known have needed EGR valves at some point but that is a common problem to all modern diesels.

The 4.4 improved on the 3.6. The only 4.4 specifc common issue is the turbo oil drain modification. Egrs again and despite the starters being the same on the 3.6, more seem to fail on the 4.4. Not a big job though

I wouldn't hesitate to have another TDV8 or SDV8

And a shorter wheelbase.

You also get the revised version of ACE, think it is called dynamic stability or something. Standard on the quick ones and optional on the others. But unavailable on the D3 as far as I know. Plus you get more engine options with the RRS including the supercharged V8 and 3.6 TDV8 and generally a lot easier to find a naturally aspirated V8 too, which is rare in the D3 in the UK.

Every day is a school day. I had always mistakenly thought the chassis was basically identical with the exception of the very expensive to fix ACE system on the RRS. You are right though 2885mm wheelbase for the D3 vs 2,745mm for the RRS

So did I - but in fact the RRS is 108.1" and the D3 is 113.6. Every day a school day

I recall somewhere saying that it was down to the packaging in the engine bay. The engine was shoe horned into the RRS and thus doesn't get the heat out as well. The proper RR was designed around the engine and had more effective cooling around it thus making it a bit more reliable turbo wise.

There's also the theory that the owners of the RRSs tended to tweak and tune the engine more often than the owners of the full fat RR thus just increasing the likelihood of something going wrong.

I had heard this too but no idea if it had any truth to or it not. The engine bay is certainly smaller!

Also the second sump. Cheaper servicing leads to the second sump not being emptied, and that's where the turbos pick up the oil

That relates to the full size RR too. The second sump plug is directly above the sub frame and almost impossible to see. The plus side is that bit of sub frame never goes rusty as it gets covered in oil at every oil change!

A local garage to me, that specialises in 4x4 engine rebuilds and gas conversions, reckons that the biggest killer of TDV8's is not emptying that second sump. They reckon the biggest killer of the TDV6 is starting the engine

Every TDV8 that I have serviced and was not main dealer before me has had a very tight rear sump plug that I suspect has not been removed

 

Lol re the TDV6!

Then your dealers do a better job than over here. Most (if not all) dealer serviced cars are never put on the ramp, the oil is just sucked out as it's faster and cheaper. I've seen clear signs when doing a first service after warranty.
