Firstly, hello. I`m Steve and I`ve registered here to do some digging (as I always do) before buying...if I actually do so.

Is there any difference regarding reliability between the 2.7 and 3.6 diesel engines? I`m leaning towards the 3.6 as it seems more capable of powering a very heavy car. I recently drove my mates 3.6 and wasn`t really impressed but, I am used to slightly quicker motors, hence my quote in the welcome section...sacrificing speed for comfort

I`ve never worried about mpg as I only do about 5 - 6k a year but I think even I would find a petrol RRS a challenge

Cheers.

Hi & welcome,,if you only do that sort of mileage I would be looking at a V8 petrol supercharger,,you will still have the power,economy might be down slightly but for the mileage you do probably wont make much difference & the reliability is better with the petrols.

Hi Andy, thanks for that. Got me thinking now I`ve literally done just under 20k in 3 years in my ST. Working 4 on 6 off shifts helps a lot

If you want comfort go for a full fat, basically the same in regards to running costs and seem to be marginally cheaper than the sport. They come with the same engines and usually have more toys too!

Whatever you go for (full fat, sport or discovery) I would try and avoid one with a sunroof. I personally don't think that for the size of them they're worth the trouble (90% will leak and flood the car at some point).

Hiya. Yeah, not really a fan of sunroofs...especially with x 4 windows plus aircon Not a fan of the FFRR to be honest....purely an aesthetics choice for me

The sunroof leaking is normally a very simple fix thou.
And they come as standard on the top spec ones anyway! RRS Autobiography SDV6 19

Prevention is better than cure and while it's a simple fix, if you don't check it regularly the first you know about it is when your carpets are wet. Which will cause long term damage.

Cheers, good to know.

I test drove a 2.7 before buying my 3.6. The 2.7 was a lovely car but felt very underpowered when pulling out onto the dual carriageway, was much slower than Im used to, a 0-60 of 12s for something that has a Sport badge on the back is a joke. Tdv8 was far more acceptable

double post it seems  2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

it's a no-brainer really: the TDV8 doesn't break cranks  --

The 3.6 has a reputation (somewhat deserved) for turbo issues. This is caused by the engine being too big for the engine bay so the turbos are sat too low. At off road angles the turbo can be below the sump which is a bad thing. So they designed an oil drain system using a pump. All works ok but getting the turbos hot and then just switching it all off seems to cause oil to burn and the seals fail. Leaving the engine idling for a minute after a run is suggested as a defence against this.

The 2.7 has possible oil pump issues. There is a batch with a revised (to make it weaker!) oil pump casting. This can and does fail after a belt change and is usually terminal. A revised-revised (to make it stronger) oil pump casting is available and recommended as a protection against this failure.

That's probably the big difference between the two. The 3.6 has timing chains whereas the 2.7 has belts. The belts need changing at 105k miles / 7 years (whichever comes first). The chains are fit-for-life.

Both engines suffer from ancillaries issues but the 3.6 perhaps has more alternator issues than the 2.7 but it's not a big difference it seems.

The 3.6 has dynamic response anti-roll bars. These are known to leak and can, if you're unlucky, require a replacement bar. This is a big job and will cost £1500+. Either bar can fail.

Both suffer from suspension bushes wearing out. This is common across the D3/D4/RRS and is independent of engine fitted. RRS bushes are uprated over the D3 but still wear out. Usual areas are front lower arms, both anti roll bar types (dynamic response and normal bars). Others will need doing over time. Mine has had a spate of rear hub bushes recently - they creak horribly as they go so you'll know if they need doing. Mine is coming up on 150k miles though. Just rock the car from side to side whilst it sat on the drive. The creaking is very obvious.

Many thanks for that, great help Hope you didn`t just type all that up though
