Indeed, the catch can has no stuffing in it, hence diminishing it's ability in capturing oil fumes. You guys input got me thinking about what would be the best media that would allow the fumes to condensate on and at the same time conduct the heat to the outside aluminium wall of the tank. I went to the grocery store and picked up stainless steel spiral scrubers and copper scouring puffs. After shaping them in my hands, the copper ones would appear to be a better choice, letting the fumes thru it more easily.

Soooo, some time in the future, I will be pipecutting the tank open, stuffing it with copper scrubber and tigging it back together.

IMO, 3 port is better, letting fumes in along each side of the tank at a lower velocity. The ports are flush to the top of the tank, no straws. The pcv port is the center one. the extra fitting is 1/4npt/90/3/8. The black tube is 3/8" synflex.
