correct, the one at the bell housing is hard to get too - so hard that when I could not remove it myself, I sent the car to the mechanic - hopefully he can finish the job.

Question though: The TDC sensor, when I traced that back from the block, I noticed it went to the X11 port on the side wall - does that mean it deals only w/ diagnostics, or does it route elsewhere after that?
