I pulled the front cover from my 1987 560SEL to put in new rails and a chain and I wanted to ask if there is a specific mark on the distributor intermediate sprocket (between the Crankshaft Sprocket and the left/driver's side camshaft sprocket) that I need to line up when the vehicle is TDC? I have a drawing of the engine that says that there is a timing mark but I could not see it on my sprocket. I figured that when I drop the distributor down I could align it so that the rotor points to cylinder #1 but maybe I can't if there is some mark involved and I am not right on (and I don't want to figure that out after I put the cover and everything else back on).
Cheers.
