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

      I don't know, I've never done it that way, but 1. While it is an interference engine, there is still clearance between the valves and the piston at all points in the regular timing cycle 2. There is not a lot of distance before you can't catch the top of the valve stem any more I don't know if 2 is greater or less than 1. But 3. If it doesn't work out you are f**ked, engine is coming out to disassemble so it is a big bet.

      Semi slicks are horrible for road use, just use a high performance road tyre unless you really need the maximum grip. Noisy, unpredictable (amazing, until they are not), expensive due to very high wear and not good in cold and particular wet. And yes, it is a thing to store cars on stands instead of tyres if you know they are going to be parked up long term.....but who ever realises that a short park is going to stretch into years before it is out again!

      I know in Australia you'll definitely get above 30c. Parked in the shade in Summer you'll be above that. 馃槢 But in cooler climates, you might get that warm driving on the highway for a bit, but you'd never get to full heat temp. I'll try and find some of my historical tyre temps between Aus summer and winter (be aware immin the warmer area of Aus too.)

      I get that taking off the head is best but that's a bit much for "just" valve seals. I was just under the impression that one would be able to rotate to TDC and be able to temporarily drop the valve without losing it and effectively having to remove the head to then recover it. I never knew people actually pushed rope into the cylinder to do valve seals hahaha So just to confirm, just going to TDC will not work? In that case I know when I do valve seals I'll maybe just remove the head and do some other things while I'm there, or just wait until I do an engine build.
