I luckily work at an auction so when I was confused I would wait til another 1986 vintage 190 would go through and pop the hood and have a look see. But alas the best thing I have found is the MB Maint CD. That baby has helped me do more things with my 190 when fixing it than anything else and of course I try to bring that knowledge back to the forums.
