While I'm waiting on parts, I've been studying-up on the procedure.
I found this video tutorial, which seems to be very comprehensive.

However it leaves me with a couple of questions I hope y'all can help me with:
1. At about 1:52 in the video, they say "if locking camshafts on left and right cylinder head is desired, a specially modified camshaft locking tool is required". Does that mean it's OPTIONAL to lock left & right side? What am I missing here?
2. Is it absolutely necessary to remove the A/C compressor to do this job, as described at 2:22? I haven't heard anybody else say they've done this? Will I have to vent the system then?
3. Somebody explain to the dummy here (me) why it's necessary at all, to remove all of the tensioners and lock the cams? Is there really that much tension on the chains that they'd pull the shaft out of alignment with the bearing / bore when you remove that bearing? Is that what's going-on here? I mean, why I can't just pop the one out and the next one back in, the way all the rednecks on the other youtube videos do it?
Hit me, will ya? but don't be too harsh. :-)
thanks in advance.
