I'm sure I was reading somewhere that stock rocker ports are -10 size.Catch cans on holden 304 efi rocker covers
If we want to keep things reasonable standard for emission, and legal registration purposes how we get on with running catch cans and still making the system legal
Had a look here on parts shelf and have a few stefs catch cans (single- hose), was thinking of utilising this by running the 2 rocker cover vents into the one catch can and then running a hose out to pick existing holden emission hoses
Is there a know fitting which can slip onto the holden rocker cover cent which can be adapted to AN 8-10 fitting
I see there is a fitting made for R26/Barra etc.
This is 22mm OD was thinking could drill out the inside to suit holden aluminium hose connection 16-17mm OD, then epoxy the fitting on![]()

I've been thinking about this same question (as a future bridge to cross).
I re-did everything to stock style when fitting the COME TTB Mani.
Basically the drivers side cover breathes fresh air from the air box (I fitted a breather filter). And the other side goes through a PCV valve to the throttle body on the engine side of the blade.
Basically the air goes in one cover, through the motor (collecting vapour) and out the other side.
So catch cam should go between the passenger cover and the PCV.
I was thinking with mine though, I might breather both sides, and drill the manifold (-12?) and run the PCV straight out from the valley. I then have the option to go into a catch can and then through PCV back to t/b
