I can't remember if I passed on some resources to help you get along with the 6.5 Diesel found in these little bussessesses. I think these memory lapses might have something to do with the 60's … and Richard M. Nixon … but I digress.
The GMC 6.5 diesel. Some folks like them, and some folks don't … not very much anyoldways. Me? I know there are better diesel engines out there … but this one is already in the bus … so I figure it pays to learn how to keep it healthy. As John Muir, the father of doing the VW van thing on yer own said a LONG time ago, “Come
to kindly terms with your ass
, for it beareth you.” John didn't have the luxuries of computers and the internet back in those halcyon days of yesteryear … but now we do. And there is a whole lot of more good stuff on the internet then just those far-out fractal vids on Youtube.
There are a couple forums dedicated to keeping the 6.5 Diesel Engines up and running. The Diesel Place is a good one. Chock full of diy and fwiw, you can find information on doing repairs and mods to this engine here: 6.5 NEWBIES - **START HERE** - Diesel Place : Chevrolet and GMC Diesel Truck Forums

As I mentioned, Youtube has more than just great tunes. If you look around, you can also find a couple vids on You tube about keeping the 6.5 alive and well:
FWIW (I think “bomb proof” is a bit … optimistic. The videographer (?) does not really address the unharmonious harmonic balancer, a throughly blown head gasket, or a cracked head. But most of his stuff is right on, Man.
Here's a good one on a perfectly wonderful bad PMD (btw: Pump Mounted Driver PMD
, Fuel System Driver FSD
Just finding the dang thing is half the battle so pay attention.
If you are REALLY into arts & crafts or desperately outta dough, this one tells you how to REPAIR a pesty PMD:
... but I would call that a lesson for really advanced players.
If you're flush with cash 'cause you sold your stash, you can find a repair/relocation kit complete with NEW-IMPROVED (or at least working and better than your old dead one) PMD for about $240. Just do a google search.
