DieselAddict,

I have done a number of valve adjustments on 220D & 240D engines, and I normally do them on the driveway, outside. I rotate the engine by putting the car in 4th gear, and pulling it towards me while I watch the camshaft. My driveway has a slight slope, which helps. When I am done, I push it back (up the hill slightly, so it is a pretty slight hill) and check them again, pulling it back down the driveway. I use a brick in front of the front wheel to prevent the car from going too far.

I have also used the power steering pulley nut but this is not endorsed by a number of pretty savvy guys on the site. The pulling mode works fine and you always know the direction of rotation is correct. Jim
