TDC on 300E
 

:dunce2: I feel really stupid for asking this question, considering one just like it was posted, but i am trying to figure out what is tdc on my car. there are two notches on the back of the timing gear. at first i thought this was it, then i noticed what looked like a small drilled hole with a ball in it on the front. then i thought this was it. i am confused which one it is?

I used the smalled drilled hole for TDC, my car is in time.
