Just to update this i took it out while i had the intake off for head work and flushed it multiple times in a parts washer, painted it and put it back in.
Looks clean as a whistle inside and i can actually see the filter in it now.
The hose for it to the PCV valve is rock solid and really interferes with trying to get the distributor hold down bolt, i dont see anything looking for a replacement so im hoping to fit in a catch can between this and the PCV and run a softer hose that can move a bit when i need to get at it.
