I'm doing the guides now. It's a big job in the sense that a lot has to come off the engine and out of the engine bay but it's not so huge an undertaking that it cant be done with mostly normal tools and a weekend in the garage. FCP, ECS, AZAUTOHAUS, and other vendors have "kits" that they sell which contain everything needed for the job. If you think you can take this on yourself I'd recommend you real the German auto solutions m62 timing guide diy and the beisan systems vanos diy guide (you don't have to do the vanos work but there is good info in the document) there are a few other diys posted on the forums that you can google. The 4 things you will absolutely need are 1. A ft/lb torque wrench. 2. An inch/lb torque wrench. 3. A 450 ft/lb impact for the jesus bolt (google it). And lastly the timing tools for the m62, I highly recommend the GAS set, it's the one I have and its amazingly easy to use. Otherwise if you have a garage, some mechanical skill beyond changing oil, and a garage or driveway to park the car in safely then you should be able to do it no problem. Also download the m62 torque specs doc, the one I have I got from e38.org and follow it to a T or you will break stuff.
