I'm going to have to install a new oil drive/cam sensor on my 2000 XJ in the next few days. I can't mark down the position on the old one (long story). I've read a few guides and I'm somewhat confused on a few parts:
1. The 2000 Cherokee's don't have timing marks, so there's no way to set it to 0/TDC that way.
2. I believe that due to #1 above, your next step is to use the finger over the spark plug trick. But, do you stop right when you feel air, or when you feel air and keep going till you see the top of the piston hit max height through the hole?
3. So far I've looked at two brands of cam sensors/drives at the parts store, and neither of them have the alignment pin hole. Is this normal now? If so, do you just eyeball it using the million pictures of the internet of where it should face? Looks like ~11 o'clock.
4. Some of the guides indicate using a special socket to turn the motor clockwise, not just any old 19mm socket. Why is that and does that really matter?
5. I read on one thread that if you install it on a 2000/2001 you need to take it in to a dealer to have them flash the computer to correct timing issues afterwards because unlike a distributor it is 100% set by the computer. Is that true?
Thanks!
