I’ll take before and after photos of the holes on the PCV on the next one.

GM apparently corrected the undersized PCV holes sometime after 2013?

Can you buy a PCV with factory enlarged holes?
Yes. It costs a Shinto load because it comes with a free valve cover.

Thanks GM ya f%^#ers.

This is what I pulled out of the VE.
Gunked up as!
I used the one I pictured earlier.
Came out easy as too. Could have used pliers.

So used a cleaned and modified spare in the VZ.
Pulled the VZ one, cleaned it and modified it. Used it in the VE Calais.
Can't say I have ever done many things on a car as simple and easy to do as this, that has made such a difference to way the car drives.

What a difference to drive! Instant change. Wow. Much smoother. Will get better as fuel trims improve in the next week or so.

hey mate, sorry to reply on an old one, i couldnt find the way to PM you. just curious, i did the PCV mod and re-installed it, does it hiss a bit more since opening up the holes with the valve hose atatched?

Cheers,

Shouldn’t make any noise.

Shouldn’t make any noise.

it’s weird because when I have the valve in the hose out of the rocker and I cover the holes, there’s no hissing, closed suction should I say. But when it’s in the rocker, it starts hissing like it’s getting air from outside. if that makes sense.

more thread tape maybe?

Thread tape?

Inside the PCV pipe and it’s connector is a small rubber o-ring. It’s possible it’s been damaged. Have a look in there. Inspect the pipe for damage.

Insert the PCV valve back into the cam cover and use red thread lock this time.

Make sure the PCV is not misshapen and the PCV pipe/hose is good. The ends that connect to the manifold should be inspected.
You can replace the brittle hose ends with some suitably sized hose. The pipes them selves are still available and easy to get.

Yea my plan is to replace the system when I put in my Catch cans in after easter. But will tend to the pcv tomorrow when I get red tape, as I was using yellow. Cheers for the help!
