hey all, i'm planning on adjusting the valves of my 280CE this weekend. i've got about three days to get it done so i've got plenty of time to mess up and get it right...

i've done valve adjusting on turbo diesels before, is this anything like that? do i absolutely NEED to buy the special/bent wrenches?

i've got this to go by: http://mercedes.thatchermathias.com/w123CD1/Program/Engine/110/05-210.pdf

in Step 1, it says to "remove rubber seals." what are they referring to?

is there anything else i should purchase to replace if need be while i'm in there?

can i turn the engine with the power steering pump? do i need to remove the spark plugs if/when i do this? can i use a crescent wrench instead as i'm pretty sure i don't have a 27mm socket?

thanks for the help, i really appreciate it!
