Yes parts can be a bear but thankfully this Forum exists. Anders and v8volvo have extensive knowledge of these interesting 6 cyl oil burners as well as other internal combustion air pumps..
and Anders also has a very impressive part/car collection which I have seen first hand. I have dealt with both of them and I am very thankful for their input.
The Volvo with the VW Diesel is rare indeed and a great car to drive! Sometimes I envy the Mercedes Dieselers thinking how carefree it must be to drive one of those Legendary 5 Cyl machines but at the same time I think they wish they had a Volvo Diesel as the performance and sound of the overgrown rabbit engine is very pleasing....
