I suspect there's one of these in my future, although I replaced the original with an OEM part 20K miles ago.
But my 6.5L TD ain't yer Daddy's engine, being a Peninsula Diesel (AMG) replacement with Phazer, non-wastegated TC, and Hi-Pop injectors - in a 16,000+ lb. motorhome. Replaced 12/06, the new engine has 11K miles on it, and I'm delighted with the performance.
