VERDICT & RATING

Verdict & Rating

Rating:

5

out of 5

86% confidence - based on 620+ real UK enquiries, specialist rebuild reports, and JLR TSB documentation.

The AJ133 is a glorious V8 with a legendary soundtrack - but early chain tensioners can fail and coolant leaks are common - buy post-2013 if possible, or ensure tensioner history.
