I came across a good deal on a he351ve. It's going on our 24 valve along with a Fleece controller. It seems that the shaft is hard to turn and there is excessive play in the shaft. The guy I got it from said the truck only had 30,000 miles and was smoking like crazy, so the dealer was just throwing parts at it, but it ended up being a cracked head next to an oil gallery??? Somehow he got to keep the old turbo, which I thought was odd. Anyways, I think I should at least tear it apart and maybe rebuild it since I have next to nothing in it. I can't find a rebuild kit, and was wondering if anyone else has done this. Thanks
