Hi all thinking of chopping my l322 4.2 for a 4.4 sdv8 l405.

My issue is initially I looked at 3.0 and there are so many with seized engines so looked at 4.4s and there seem to be more and more of these with knocking engines which made me wonder how high mileagewise have people got on these? Current stable:
2006 BMW M6
2007 4.2 V8 S/C FF
Gone:
2002 4.4 V8 FF

There used to be a mileage thread somewhere.

Anyway, I've done 151k and still going strong. Hopefully not tempting fate, but it's cost me very little and been one of the most reliable cars I've ever had. I've only just changed the >10 year old original batteries - and they still seemed fine

Here you go https://www.fullfatrr.com/forum/topic47597.html?highlight=miles

You will see that there are quite a few very high mileage SDV8's!  _______________________________________________

Still only a couple over 200k - I am seeing more and more 4.4 failures on autotrader and eBay now nearly as many as 3.0 and 3x as many of those were sold Current stable:
2006 BMW M6
2007 4.2 V8 S/C FF
Gone:

Well that thread was a while ago - I'm on there at 100k and currently on 151k.

Not many over 200k - are you referring to SDV8's specifically, or including the 4.4 TDV8 ?
The SDV8 is max 11 years old, so not surprising many haven't yet clocked 200k......

Mine is on 124000 still sounds sweet 2016 4.4 diesel

350 000km personally I know

My 2015 4.4 SDV8 has 135k on the clock fully maintained and I think another 135k will be taken in its stride.

Amazing cars.

I've just sold my 2013 155k SDV8, which sounded perfect to me. No engine/turbo issues at all.

It helped that most of the miles were on a motorway and I changed the oil for a good 5W30 C1F every 8-10k miles. Current:

I’ve only had my 2016 sdv8 for a few weeks but I am on 148K and running silently and sweet as a nut (please God, I’m not tempting fate, I promise 🙏)
Did some maintenance as soon as I got it such as oil changes, and this week an o ring on a coolant pipe and I cleaned the adblue system. Did a 420 mile trip last week, wow, this thing is on a different level (literally 😝) to anything else.

With that mileage & a new car to you, it may also be worth a gearbox flush. Search for Bodsy on here.

If you can feel it change gear, even slightly, then it probably needs doing. I didn´t realise that until after mine was done & then I could no longer feel anything as its shifted.

I read in km now 260,000km with the 2017 model SDV8 on the speedometer, with a 2013 model it was 367,000km. L405 SDV8 2017 + Lancia Flavia Coupe 1964 + RRS L494 3.0 SDV6 + C220CDI Convertible 2021
