Lots of rain over there!
You have an 88 with a 2.8, thats weird. You sure it's not a 3.1?

Sounds like the valve breather. It's needed, unless you reroute some vacuum lines and put in an open air valve breather.

Sounds like vacuum lines, you need the ones for your FPR and PCV system at least. I took off all of the other lines going to the TB for the EGR and charcoal cannister.
