need help with venting hoses
hi - got car back from shop after cam swap and found 2 heater hoses just hanging under K member. Traced them back to vent ports from the valve covers.
Rear of drivers side VC connects with a "Y" to rear of pass side VC and continues all the way down to k member zip tied to rack.
Front of pass side VC also goes down to k member zip tied to rack.
I thought there should never be un-metered air able to enter the closed system so this baffles me. Mechanic told me to add catch catch can if the leaking oil bothers me.
Anyway, see my pics attached and please offer suggestions.
In current configuration, do you think this is costing HP?
Or does it add to a rougher idle?
One of the pics i'll attach is an old vented catch can i just found in my garage; it has 2 ports on it. Should i attach the 2 heater hoses that are currently hanging down to it until I purchase a normal catch can (the ones that use the vacuum from the tbody ports and intake port, numbered 1 and 2 in attached pic)?
Does it matter which hose goes to #1 or #2? They seem to be both equal in terms of pulling vacuum.
Thanks!

Get a catch can with a pcv valve "Mighty Mouse" can comes to mind..
Run the driver side hose around the intake and to the throttle body barb..
Run one hose from the passenger valve cover to the non pcv Inlet on the catch can
Cap the other passenger vent line on the valve cover
Then connect the pcv outlet of the catch can to the intake manifold just behind the throttle body, on the plastic barb..

2MCHPWR, With you current CC unless the breather filter has a 1-way valve on it (very doubtful), it WILL be getting unmetered air, and will continuously venting oily stinky crank case vapors into the air and engine compartment. If you can somehow remove the breather filter and cap it, or install a Mighty Mouse 1-way valve breathe filter on (if it's the same size) then, and only then would I use that CC. For now just hook everything in the factory PCV system back up. Until you either modify your current CC, get a MMS catch can with a valved breather, or another quality CC without a breather filter on it.
Here's some that I'd recommend.

ok so for now, i just connected front port of passenger side VC to t-body port.
Then connected the other heater hose (rear ports of drivers side VC Y piped to rear of pass side VC) to the port at the front of the intake manifold.
went drag racing, 10 hard passes, no issues encountered.
Waiting to see which mightmouse CC I can use that has 2 inlet ports (that'll go to the 2 hoses from my VC's) and one exit going to the tbody port or the intake port (not sure which one; you know?).
Can has no PCV.
