I'm hearing the siren call of the L322 once more.... I was considering the 4.4 TDV8 but have seen a few 5.0 Supercharged in my price range with fewer miles which has piqued my interest....is the key weak point on these the timing chains? Is it a case of they will break and it is just a matter of when? Does the 5.0 N/A suffer more than the 5.0 S/C?

AFAIK The NA doesn't exist in the UK. In the SC the chains are a common fault after (say) 80k miles, but I suspect there are some out there that have somehow kept it together. Mike - MPx

As with any RR service history is a must.

Oil is the most important thing when it comes to the longevity of the chains. LR extended service intervals are no good in this regard.

Opinions differ on whether it's a case of when, not if.

You can sort of test the stretch / wear on the chains / tensioner by poking it through the oil cap although it's not 100% and only tells one side of the story (literally).

Make sure you hear it start from cold and then start when it's hot as well.

Good luck!
