ic thnks mate! i will order another one before i fit the can, so the 2 nd one must be fitted in the same way as the normal one on the top cover, right?

One on the rocker cover as normal, the other between the catch tank & inlet manifold.

is the second hose from catch tank vented?
the hose is pointing down, and its vented
i have read all the pages...
but i have one question and i am sure its a yes but here its goes:
does the pcv valve only open when there is a vacuum?
Thats the main reason why you need to gut the bastard if you do not want to hook it back to the inletmanifold right?

I'm looking at putting a catch on my setup (standard but with FMIC). My PCV valve is bust around the top and is now letting oil out..not good!! If I buy a new valve and plumb this into the catch can, then gut the old one and put that between the catch can and the inlet manifold, will that be correct? I don't want to vent the catch can to atmosphere, it sounds illegal and surely it will smell? So many ways of doing the same thing!! All I want to do is eliminate/reduce the oil in the intercooler/inlet to increase engine life. I'm well confused!!
Hi I am new to this forum but I would love to contribute a little experience of mine regarding OCC. I once mount it in a position where it is higher than the rocker cover and thus, the pipe to the OCC was going upward and sludge finds it hard to make its way to the OCC. Then I install it lower than the rocker cover and the sludge was filling the tank much more efficiently and air has no problem travelling upwards the pipe. I did mine this way, 2 crankcase ventilation valve going to one pipe via a T joint and then the output of the OCC to a T joint and 2 pipes into the throttle body. Is this ok?

i broke my pcv valve when i replaced the headgasket last year and from then through a lack of lazyness i suppose to order one i just run with the pipe on inlet blocked off and the spring out of the pcv valve on rocker breathing into the atmosphere.
