Watched an episode this morning on "trucks" ( one of the auto episodes on "powerblock" which comes on GRIT)....

It was all about the 5.9 cummins diesel, discussing the dowel problem ( and how to fixit), lots of mods and permanently fixing the "5th gear nut problem"...

I do not know much about these, and I do not have a diesel and don't plan on it, but I would think that anyone who has a 5.9 would want to watch this episode... Fairly technical and full of advice for upgrades.....
