97 e320 M104 crank wont spin

[clk500kid]

I just put back everything after doing a Head gasket change, Lower timing cover (the tensioner bolt housing was stripped so replaced the lower cover). As i was doing this I needed to take the crankshaft bolt and pully off to access the lower cover. as i removed the bolt it spun everything on top cams. i lined the intake cam shaft using a 4mm and the same for the exhaust side.

the problem i have is that the pully on the bottom says 40 on the TDC part. I'm trying to line it up and spin the bolt and the crankshaft to tdc. In my car its the later version so the TDC is 20 after the .1 and there is not marking on it execpt on the lower cover..there is this marking that sticks out and thats where i have been reading the numbers.

for anyone out there that has a clue on this..... Does the crank stop spinning??? i turn it clockwise and it goes to past 50 and the numbers disappear. i turn counter clockwise..it goes to 40. but i cant seem to turn the crank clockwise past that blank numbers.


does anyone know if it should keep on spinning the crank clockwise?

i always seem to do this. does anyone know what might be holding it up?

thanks for the input guys.
