ABN173, Thanks again. I found a very good thread that had some good pointers. I had read about 6.5's having a reverse direction water pump and the HMMWV engine apparently does also. I am waiting for a turbo rebuild from area diesel. I pulled a homemade turbo setup from a 1984 or 1982, not sure which one, 1 ton dually pickup. It is a turbo-master with the crossover below the front of the engines pulley. They reversed both GM cast exhaust manifolds. It must have been a kit because there was a cast Y piece I recoverd also. Area diesel is rebuilding it with a garret style turbo charger in the same flange and used mine as a core. I am not sure on all the details of how they do it but the rebuilt turbo is costing me 500 dollars plus tax and shipping. That is alot cheaper than the 2,7K banks one. I will get a flange welded to the bottom of the crossover pipe I recovered to make it easier to remove and also add another flange on the section of down exhaust for same reason. My main concern is after seeing how it is nearly impossible to access parts of the passenger side of the engine with the turbo installed.
The extra engine is something I'm considering because I don't want long down times and am tired of the difficulty of maintenance when it comes to some types of maintenance. I have purchased two more M1009's and waiting for the paperwork to clear. With eventually 3 of them I should be able to drive them regularly and have extra engines when needed. These 6.2 and 6.5 engines really have a horrible reputation. There is an ex-military guy here who used to work on them who was asked if he wanted to help and the answer was to "drive it off a cliff, he will never touch another 6.2/6.5 again now that he is out". I called two different machine shops today to get my heads vacuum checked for possible bent valves. One shop said "I'm sorry you have one" and the other shop said somthing similar. Both responses came after I first called and was asking the price for push rods and the clean/vacuum test. I think the 6.2 and 6.5 are probably some of the most misunderstood diesels out there. I like mine but will say there are some things about it that you may have to learn the hard way.
