Very nice post. It helped me out a lot. I did mine this afternoon. It took me about an hr and a half for the work, about 2 hrs for cleaning. I got it pretty clean, but not as good as you. I also went ahead and change the VANOS oil line gaskets while I was in there. Torque for those is 32 Nm (24 ft-lb). Torque 22 Nm for the M8 oil filter housing bolts. Just in case others need it. Thanks for the help, man!
BTW, I know this is an old post, but just thought I'd give props.
