Circle track guys don't have PCV's. It pollutes the incoming air charge and we don't car about the EPA either.
The VC with the breather tubes on on the left side and have baffles of some sort to keep the oil mist from escaping. If you make one on the right side VC, you will need to make something. You might see some with spring oilers too. You don't really need these in a street application.
Just the bare steel covers work well to and allow you to put the breather in with any size and style you like. Beware the raw steel ones can rust on the inside if you have moisture issues from cool temps. I just etch and paint the insides and it works well for me.
Thanks.
I like the pipes to keep oil mist far from filter.
I am looking at fabricated Al w/ 1/4" billet rail and 2 pipes already made up.
I am looking at the non circle track version also.
My favorite would be one pipe per cover; I don't have a tig.
I'll sleep on it.
So I guess the racers install both breathers on drivers side because the left hand turning slings oil toward passenger side?
You could do what I've done. Buy the covers with a single prefabbed hole in each, then machine a couple pieces of aluminum or stainless tube to a press-fit into the prefabbed holes. The holes are 1.22" on diameter, and have an 1/8" rolled lip flange, so 1.25" tubing needs just a minor trip through the lathe on one end to size it for a .005-.006" press fit. Press them in with a little red loctite, support the inside of the cover when your pressing. Works great! Allows you to make the pipe as short or as tall as you want it.
If you wanted a PVC grommet size hole at the top of one pipe you could just machine a ring to press into the pipe, to fit the grommet lip. Or machine a grommet lip onto the pipe if you are ising a thicker wall tube.
I used 1.25" x .060" wall stainless tube pirated from a scrap bin at work.

Sound good.
Think I'll get single hole covers; maybe rig some pipes later.
No lath here but maybe a shop would weld some pipes from the inside for
cheap. Unless they were confident enough to make a pretty weld on the outside. Machine shops don't seem to come cheap.
you can buy those same covers with no holes. Moroso sell a kit with al tubes and breathers to weld in. KN sells a bolt in breather tube that works well.
I can find the VC I like and some Al pipe.
Have experience w/ mig welding and tourch brazing on steel.
Never ventured to weld Al.
Hate to ruin a new fabricated cover.
