DONE!!! I did mine yesterday at 106,500 miles...
Man, what a long job. For a desk jockey, it was a great experience. I learned a lot and do NOT want to do that job again for a very long time. I will probably wait until 225K to do the next one.
The most valuable tool: The 3/8" flex head ratchet I bought Friday. Runner up- my 3/8" air ratchet. And I guess honorable mention goes to the http://www.amazon.com/Powerbuilt-648796-Crankcase-Pulley-Removal/dp/B0000TMLWQ/ref=sr_1_1?ie=UTF8&qid=1312159933&sr=8-1 Crankshaft bolt removal tool. Well worth the $36 it took to get it in my hands.
Anyway, this was the most in-depth mechanical work I've done on my own. All by myself, except when my wife held the crankshaft tool while I put the pressure on the 19mm socket to break it free and she helped get the drive belt back on at the end.
There's a LOT of BS in this job as far as the crap you have to do, remove, snake around, etc. I guess that's the deal with working on cars today. I guess there's a lot more room in this truck than some of the cars with the V6 engines, tho.
All in all, I'm pretty darn proud of myself. I hit some gotchyas...the worst was realizing the back camshaft had rolled off of TDC when I was threading the new timing belt on. It did it three more times.
I've still got to replace the spark plugs and open the valve covers up to check the valves (I don't think there's anything wrong with the clearance, but just might go through the exercise for the fun of it.
Was it worth the $500 savings? Yeah. I'd still be wondering if I could do it. Now I know.
