Yeah it just started happening after I installed my clean side catch can... Hopefully joe can give me some insight here..I'm going to trace back and double check all the connections again in the meantime .. Sounds like a pressure leak

Look at the check valves and make sure they're installed in the right direction.

I was thinking the same thing as that sounds more like a check valve or something backwards....

The only time I hear that sound is when something is blocked or the vacuum is trapped from a crossed or blocked line.

That is not a vacuum leak as you can clearly hear the squeaking get higher pitched from the increased vacuum. Then you
can hear the catch can release all the vacuum and make a suction noise when he removes the line.

Yeah I've had a DVCC on for about 4K miles and both arrows on the check valves are facing away from the catch can.

All my noises and squealing went away when I installed the revised pcv oil separator.... So I'm guessing there was too much pressure or something.

I'm having this same issue with my catch cans on my GT that I recently installed the Edelbrock supercharger. Sound more from the passenger side. It is intermittent. Does it sometimes and doesn't others. It is really embarrassing in traffic when it starts, sounds bad outside the car. I have checked and the catch cans are doing the job though. I have also checked the install to make sure the flow is correct. Any updates would be appreciated..

Give Adam a call at Tune Plus to go over your hose routing and check valve direction. You will need to run the PCV upgrade that Adam can set you up with.
