Oak,

Locate the stamped bracket that resides in front of the tensioner, the one with three holes. One of the bolts goes into the lower timing chain cover. This is the one that gets the sealant. Apply it on both sides of the bracket and bolt it up. As to which sealant to use, I used the same that I used to seal the upper timing cover.

Don't know it you've got the PS pulley bolts off yet, but try some penetrating oil before turning them counterclockwise.
