lots of oil in the IC hoses/IC - TB hose

[AlS6]

could this be a bad or failing Pressure Regulating valve? The "puck" one by the firewall?

100% normal
Its the oil fume system sucking up oil fumes from the block and back into the engine to burn in the combustion....
However the fumes turn back into oil and accumulate in low areas over time...

normal. an EXCESSIVE amount can mean somethings going on, but some oil in the system is perfectly fine.

If it is an oil film or small amount than it is normal.

I pulled thr intercoolers off a 2.7 at a junk yard and about a quart of oil poured out. If you have that much I would be worried.

Shaft seals in the turbo could be wearing allowing oil to pass through into the IC piping

when i pulled my SMIC i probably had a few tablespoons worth.

What would happen or what are symptoms of a bad of failing puck PCV?

i think its normally referred to as the "pancake" valve...searching that may turn up a few threads. all that stuff caused me issues when i first had the car, so i ripped it all out. the engines are oil sludge prone...that piece and connecting rat nests fair even worse. they get plugged easily and fill up with junk.
