I have only a 1641CC type one. With far too much of a breather box system, I think.
I would like to clean up some of the plumbing. What's the requirements for this size engine?
(There are now; no future plans for a larger engine). Does reducing this system have a positive or negative effect on engine performance? I'm in California, so no smog require, but it is titled as having a Req.Ecs: PCV

Shoot you aren't even plumbed into the valve covers! I like the clean 356 look of the CB 1771 Breather tower $55. It has 4 or so places for possible fittings.
Greg;
The valve covers are plumbed.

For a 1600 motor, nothing. Remove it all and go back to the stock setup.
Stephen;
What is the stock set-up? Where should I look for a drawing for the correct stock set up. My Haynes manual is not clear to me. Thanks, Art
Art - here are pics of stock set-up.
On your set-up, it looks like you can simply disconnect the tubing between oil stand filler and breather box at the breather box. Then run that tubing down through the little pass-through (hole) at bottom of engine tin below oil stand.
Be sure that the length of that tubing is long enough so that the end of that tubing is at least a couple of inches below the oil pan. This is so the atmospheric pressure (at the end of the tubing) prevents excessive venting.
OMG
No wonder I haven't seen these in photos. Learn something every visit. Reminds me of a certain gray water system at an undisclosed location in the Santa Cruz mountains.
So now, if I go this way, there should not be any operational/performance changes?
Venting to the air is so, um . . . retro -?- Infernal combustion engines of all stripes have had their crankcase gasses vented back into the carb or injected into the exhaust for quite a number of years now. This vent as shown would be patently illegal if there were rules for such things for these cars. Just running the hose to the top of the carb would be a better way to go. That is all I have on my 2332, and seems to work fine.
Art,
You asked to clean up the mess, this will surely do it. 1600 does not build that much pressure, and I used the stock setup on my 68 Ghia for the 10yrs I owned it with no issues. Sometimes, if you run it really, I mean really, Hard, you will get a drop of oil out of the tube. Or you can do as suggested and run a hose from the filler to the top of the carb.
Jim, Thanks for the photos.
Stephen
Thanks guys for the help.

Personally, I'd leave the breather system the way it is and hide the electrical and plug wires.
Ron, yes the red plug wires standout and add to the messy look. I'll give it somethought. Good idea!
Overdoing anything on a Speedster is simply sign of "The Madness" setting in. I'd leave it but add AN fittings and stainless covered hoses.
Greg;
Does a beginner, put together his own hoses with fittings? There has to be some special tools involved, especially to cut braided stainless hose.
Art
No real special tools - can cut with big tin snips or hacks saw (and trim with HD scissors). Does get a little costly.
