My new PVC intake oil catch can and how to build.
Let me know if anyone is interested in using one of these and I'll post a more detailed how to.
With discussion of vacuum on the catch can here is my solution.

This is the main ingredient.

It has removable foam inside of it with a removable top. It has a 5/8 hose connector that you can tap to your intake.
The pvc compression coupler (in the pictures) has holes in the screw on caps. I just epoxied a bottle (aquamend cures white) into one of the holes.
This will allow for your intake to put pressure on the crankcase and the oil will deposit into a removable catch can that can unscrew off. The oil breather on the top also has a removable top which you can take off to clean the filter. This filter will stop ANY oil from going to the intake. I also drille a tiny hole into the catch can bottle just in case it filled up it would have overflow protection and not back up the crankcase.

i hear these work pretty well.... simple one-time purchase, proven to work, and no need to drive somewhere to get a bunch of odd parts to slap something together into these beautiful 11,000 dollar machines.

just check their "overflows" and order the 1 Pint Mini breather with ONE fitting on it. Order one in clear if you like so u can see the levels inside it if it's catching anything.

You know seeing as it was only a couple of extra inches I went ahead and ordered the 1 quart version as it had a 3/4" (or similar) inlet available...
It's only an extra 4" of height and 2" of width...Ought to fit no problems...Seems like the extra couple inches of dimensions justifies not having to deal with rigging up a fitting for the right size...

Top unscrews, the foam is removable and you clean the foam in some sort of aceton I would think. It would be really hard for oil to get in the foam though. It is more of a air filter. Because of pressure the oil will go to the can and the only way oil could get to the filter is if the can filled all the way up past the bend that goes to the crankcase. Probably 3-4 cups of oil/gas but I have also put a small hole into the bottle which leaks it into the hull just in case.

Yall are missing the point. The jazz catch can doesn't provide needed vacuum to the crankcase.
When you installed the jazz can you went away from the original attention of the intake to put vacuum on the crankcase.
The downfall of the stock PVC was it gunked up your IC among other things. This is for the people that would like vacuum on the crankcase. If you don't want vacuum use a jazz or oil catch can with a filter on the top.
This isn't something you will problems with now, it will be something that effects you down the road.

I've read plenty from other parts of the internet that prove otherwise.
GTXX is a very knowledgable guy and he agrees. Again this modification is for the camp that would like vacuum. Look at the attached picture he seems to think vacuum pressure is needed.

Read here in GTXX post....
"I have not studied the crankcase ventilation system on the 4 tec engine"
Go look at a Sport bike forum (suzuki Hayabusa, Honda...ect...) Ask them if they have vaccuum on their crankcase...

Note: Installation requires drilling manifold for vacuum supply

However the rotary valve breather system on the Harley-Davidson (which creates a vacuum in the crankcase,
I could go on and on if you like , straight from motorcycle sites.
I'm doing it if people don't think you need vacuum then go for a breather. It seems to be a contraversal subject even in the motorcycle/car world. Funny thing is the solution to fixing old cars with oil leaks is to put pressure on the crankcase.
I'm not real technical about engines but from what I have read you need it. I'm doing it because what is it going to hurt ? 5/8 hose to my intake isn't going to hurt my performance and if it helps in the long run then bonus.
