Catch can failure?

[my third 256]

It is inside the original hose , I just used a joiner and new hose and left the original hose connected to the rocker cover .

x2 thats the easyst thing to do orpush it out with a screwdriver

I can't open that document yet. But what you're saying is I need the valve in there? Does it help create back pressure or just prevent water, dust, and moisture from going into the crank case?
Thanks for the info, this is interesting

Ok, so found that restrictor yesterday in my shed, popped it into the new hose, but what exactly does this thing do? I would have thought that restricting the crank case would be a bad thing?

My catch-can had an orofice that was causing a slight restriction and increased pressure in my crank-case.
The over-pressurisation of the crank-case caused my turbo seal in the compressor side to leak.
There were other issues aswell, but ultimately, I had to replace my turbo.
In my car I found the best option to make it work was no restriction or valve between the PCV outlet, through the catch-can, and into the inlet after the air cleaner.
Crank case pressure can = worn piston rings, worn bore, possible crack. Not good

Interesting, why does Nissan put that in there then? How did u test for the pressure? Is that something anyone can do?
Cheers

Well, I don't really want to say because they have been a huge help with so many things I've done to my vehicle which is why I bought the can off them. I'll just say its a custom fabrication place and I have read on this forum SINCE buying it, that they are notorious for poor cans; regrettable considering their other items are amazing and the customer service is well above my expectations, they even sent me a free replacement can to see if there was any dramas with the original.

I'm going to do a complete clean this weekend and them drive for awhile, check catch can after a week and see where I stand. If I'm not happy, I'm going to get a Provent and compare notes.

Sounds good! How much oil is the can collecting? Is ANY oil going all the way through?
