Bought it May 15, 2007 with 90.540 miles and now has 116878 miles. It's been to Illinois and back twice to off road to the top of mosquito pass at 13185 feet. The only thing that I have done is lock tight power valve screws, when I put the Ngk Iridium plugs in at 105000 miles and a month ago just replace all the fluids and ended up the transfer case fluid looking original, really black. The only issue with it when I put a K&N filter in it, was the maf acting up for a week, with the code p0171, I ended up soaking the crap out of it with Maf cleaner a couple of times, and now it's been 2 weeks with out check engine light. keeping my fingers cross. Also it average about 80 miles a day to work and back, mostly all highway miles. I think this a very dependable engine, and should be able to get 250000 miles out of it no problem, with of coarse routine maintenance.
