Catch can and PCV routing I noticed that all the catch can PCV routing ignores the vent line on the passenger side of the motor. Wouldn't a proper catchcan setup include both lines? From the passenger and drive side valve covers? I know the passenger side is more of a vent tube but does oil still get sucked in from there?
the tube on the front of the valve cover to the Throttle Body is the Fresh Air, or inlet for the PCV system to allow fresh air into the crank case while the PCV system sucks out the vapors, If you notice that the two ports on the passenger side.. only one will be a vacuum source and the other is just routed through the TB to get clean filtered air so it will not suck in junk. If anything, you will notice a bit of vacuum coming the fresh air tube on the valve cover side...

i streamlined my pcv routing when i had to replace some of the hoses.
i capped off the passenger rear vent, and just ran the vacuum line from the drivers rear.
that way fresh air enters the passenger valve cover, pulls down through the block, through the crankcase, then up and out the driver's side. then around the rear of the engine, and up to the vacuum port on the intake manifold.
if i can track down a T i may add the other line later. but or now it worked.

all i have is this drawing i did.
basically just take out the Y in the back right, and cap off the rear outlet on the passenger valve cover
i assume you wanted REAL pics...but i don't have one.
