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

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:

2007 4.2 V8 S/C FF

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
