I would add that the flat gasket behind the sight glass has some holes in it, so oil can pass through, but it separates the main body of oil from the drain plug and will not allow all the heavy dirt/metal particles in the crank case to drain out with a normal oil change.  I had to remove the cover once and found a lot of junk still in there, which I washed out with solvent.  I have been using the factory recommended #46 hydraulic oil up till now, and have found it gets dark, (dirty) in about 20 minutes of use.  I just ordered some of the "royal purple" stuff, but I didn't know it was really "purple", so I think i will get a different brand that is clear next time, so I can see when it gets dirty.
