When you are removing the timing chain housing, there are two oil feeds you need to remove. The first one is the oil feed connecting the cam housing to the timing chain housing. Undo the 10mm bolts and yank it off. There is an o-ring on the connections that would be a good idea to replace. Unfortunately, I don't think the rebuild kit Pelican sells come with them.
The next is the timing chain tensioner. Be careful when you remove the bolts, the tensioner is under spring tension.
I did not remove my timing chain ramp (not sure how or need to), so I jus popped the end next to the cam out of the lower chain ramp to remove the timing chain housing. See pic below.
On the 964, there is power steering you have to deal with. I used the cam tool to hold the cam steady, then just remove the remove the bottom bolt of the power steering gear/belt drive. Take of the gear, undo the bolts and remove the whole power steering assembly.
