I just did mine a few weeks ago, and wanted to weigh in on this, too. I wasn't planning on doing it for another few months, but then my timing chain decided to jump a tooth because of broken guides, REALLY worn tensioner, etc. after 125,000 miles. I went with the kit from engnbldr that uses the driver's side steel guide also, and Ted was super to deal with, and got the parts to me very quickly as I needed to get this truck back on the road. I was also impressed with the quality of the kit-- it's especially nice not to have all the gaskets folded up! I would definitely go with his kit-- the price and quality can't be beat. I would have preferred to have both guides out of steel, so if I went back and did it again, I would have purchased the steel guides from DOA separately, and bought the basic kit from engnbldr. You'd come out WAAAAAAAAAAYYY cheaper than buying the full kit from DOA with the steel guides.

In response to other questions-- I didn't pull the head, and was able to get everything sealed up again with no leaks, without globbing up everything-- I might add. <img src="/forums/images/graemlins/butwiggle.gif" alt="" /> And you shouldn't need a puller for the crank pulley-- it's a slip fit and has keyways-- so there's no need for it to be pressed on/pulled off. When putting it all back together-- it is critical to make sure you have everything lined up, and have the driver's side part of the chain under tension. Other than that, it's just a lot of disassembly, cleaning, and reassembly. I took my time, and that helped, too! If you have A/C and power steering like me, then buy some new belts to throw on there, too-- so that you don't have to undo all of them again in the near future to get at that fan belt that needs replacing!!
