Quic Q on TDC/Timing

[elkadi]

Hi
-On the TDC, is it the short pin (according to gillybenz) on the timing cover that needs to line with O|T or is it the end tab on the TDC sensor (according to the CD Manual)?

- On the timing cover: I have one bolt lose on the lower timing cover and it is slightly separated form the front of the engine at that bolt. Do I really have to take the whole cover off in order to reseal it? This involves removing the harmonic balancer and if I don't have to, I would rather not do that?
Thanks alot for your help...
