PCV hose diameter?

bcfromfl

I've tried to use the search extensively, and haven't found an answer. I'm upgrading to TopZ's A2A system soon, and am going to add a dual catch can system with breathers. I found a good-looking catch can from Damond Motorsports, and they have two models: one with 3/8" barbs, and the other with 5/8".

The only somewhat helpful info shows PCV hose sizes for our car in mm, but I'm still unclear. Also, the FSM is no longer online (at least where I can find it). Which would be the best match...3/8" or 5/8"?

My speed shop recommended using MickeyMouse catch cans, but I can't get them to respond to their web form for questions. Anyone have an alternative phone number for them?

Thanks!

3/8” will be fine- just use a hose designed for pcv; that way it doesn’t collapse
Pretty sure oem is close to 3/8”(9.5mm)

Also you can just remove one of the hoses from front of intake & slip an open end wrench over it (behind nipple) & size it that way....but I’m pretty sure it’s closer to 3/8”

OK, so, Damond will put together a package for me of what I need, but since they don't make a specific kit for the Z, I'll need to tell them what to include. To be on the safe side, how many feet of hose, and how many L's and/or T's should I tell them?

Thanks!

oem, you should find that the PCV is at 3/8 ID and the valve cover breather is 5/8ID If you buy the CJ Motorsports valve delete, you will be running -8an 1/2ID to a catch can ( in most cases)
