Default Catch can location question for my 93'

My PCV valve is on my passenger side head and the line runs to the TB. Do I add it in-line there?

Also on the driver side of the head where I guess 95+ cars have the PCV valve is a hose that hooks back to the manifold, do I put one there also or leave it alone?

I searched this already but everyone seems to be talking about the 95+ manifold where the hose is under the TB which mine doesn't have.

Thanks

the piece coming off of your passenger side valve cover is not your pcv valve. This is a ccv (crank case vent). Your PCV is located on the drivers side of the intake manifold and then it reconnects to the intake manifold about 1" away.

well make sure that is what it actually is. Mine had something that look like a pcv on the valve cover but it was just a hollow 90 degree angle. The pcv should be located on the driver side of the intake manifold and then the tube should make a 180 and then connect about an inch away from there

It is a PCV valve. Just removed it and checked it out. So that should be a 90 degree elbow instead?

And the PCV valve is in the manifold.

yes it should be a 90 there. All it is is to remove positive crank case pressure, but even once you so that it still isnt a bad idea to do the catch can off of there. A lot of people, including myself, have just capped it off at the TB and put a filter on there for the crank case pressure to vent out on its own.
