Thanks so much for the feedback everyone. Perhaps there is a path forward here after all (especially if I had the maintenance items done before the sale).
“ There are NO timing belts on a 4.4tdv8” - this was just something that the service front desk guy said at the end. So he’s likely wrong and thinking of a different engine (was not on the report).
Is there something major that’s supposed to be done to the engine around the 180,000 km mark?
ORings seem like a logical place for the leak. I’ve seen that mentioned many times.
