Some updates:
I worked on fixing the collector leaks and also found some loose header bolts.

I then started checking all the rubber and found a split in the small hose coming from the left of the intake that goes to the Opti (not sure if this a source for vacuum leak).

Checked the PCV valve, it is not stuck but the grommet where it fits into the intake manifold is completely deteriorated and split. (also looks like a lot of oil moving through there - might pick up a catch can)

The nub caps on the TB for the coolant bypass are also cracked all the way through (also not sure if this can be a source for vacuum leak)

Thanks for all the advice, I'll be ordering some parts and reporting back..
