How to block PCV for catch can

What is the best method to block the pcv port for a catch can install? I took out the check valve, went to three different hardware stores and could not find a block of fitting with the same thread. 

What is the thread on this thing? I will order the proper fitting online.

Unless there is a better option 

Thanks

I can't tell you what thread you have but if you go to an engineering supply store or a hydraulic hose and fittings shop  they should be able to tell you what thread it is and supply a suitable fitting.

I have the same problem.
Googled and everybody said it's 1/4bsp. But it isn't!
This will screw in only 2 turns because the original part it is tapered.
The hydraulic shop ordered me the "right" one. Same thread as the valve, also tapered. But it screws in only one turn, because it's a little big thicker where the taper starts.

I will just use a good silicone end cap on the valve now.

Same issue here. A store specifically for fittings ordered me three different ones. None fit in. Insane!

I will cap it for now as well. Last resort is to cut of the thread part from the check valve and weld it to a bolt head

Just leave the valve there.

What you are installing is an oil-air separator. It effectively inserts between the exhaust rocker cover and the turbo intake. Everything else remains "factory".

Somewhere on this forum is a photo of my setup. Some people claim its not "pretty", but it works.

They aren't suppose to screw all the way in, the fact that it widens out and won't screw all the way in is what actually seals it 

go to Motorsport connections (or earls) and order one from them

      Sorry, are coilovers ACTUALLY ILLEGAL in NSW? They aren't in Vic, as long as they retain 70% of stock travel and the car is above 100mm off the ground. Does NSW actually have a law making coilovers actually illegal? RWC/Blue Slip/Engineering people not knowing the actual f**king laws boils my blood. Demand them to point to the documentation that states a coilover is illegal. (it may exist in NSW )

      But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.
