So how do you guys do it? And is the rotation of the engine clockwise or counter?
You can remove the glow plugs to release compression on these engines, although the plugs on the passenger side are a bit hard to access due to the turbo mounting and exhaust. Removing the inner fender as mentioned above will give you lots of room to work with, though. The compression on these engines isn't that bad when you turn them over by hand real slow. The compression will leak by and give you a chance to keep turning it clockwise (When looking at the engine from the front).
