Crankcase Breather Help, Understanding the Breather Ports Options

[mtc911]

So, I have researched this one quite a bit and i cant seem to find the right answer. I have a “built” 2056 with Dual Weber Carbs. I “believe” it is a 1.7 Case with 2.0 Heads on it - not 100% sure there but the engine number seems to indicate that.

Anyway

I have (2) the little Crankcase Breather Filters - one on the driver side and one on the oil fill (seen in the pictures). However there is nothing on the passenger side head. On the drivers side there is a T/splitter type thing that also pulls in a port out of the fan shroud.

Obviously these little filters are making an oily mess in the engine bay - nothing too tragic but i would like to get rid of it if possible. I have been looking at the little Cans by Empi and Scat - that look like they would work. But I’m still kind of confused.

1 - Why would I have one of these on the Driver side Head and not the passenger side?
2 - If i install one of those cans should i route the port off of the fan shroud into it? I have read both yes and no on that question in my research.
3 - Will the can really even help reduce the oil in the bay? I have read yes and no on that question too
4- attached diagram is what i was planning to do with the breather box - is this correct?
5 - is there any downside to using one of these instead of the little cheaply filters?

I have read a ton of posts on this in various forums and I cant come to a conclusion. Yet.

Thanks

I would start with removing the tube connected to the fan shroud. That is the air output for the carbon cannister and should not be connected to the crank case breathing system. Its most likely a big part of your oily mess since it takes fan air pressure and helps to push oily air out thru the little filters.

Do you not have a port at all on your passenger side head? Thats a bit wierd, maybe the heads are from different years? If you still want to do the catch can thing I would want to connect both heads and the oil filler tower.

When you say “remove it” you man just leave it open or plug it with something. Seems like you would want that fan shroud port plugged, no?
