Breather routing for 72 1.7L, Where should this hose connect? Options

[jcd914]

I have found several threads on breathers and a few hose routing diagrams but none seem to address the set up on my car.

I have a 1970 914 with (I am told) a 72 1.7L engine in it. It has a breathe set up that is closer to the 2.0L I have than the 71 1.7L I have.

The 72 1.7L has vent tubes in each head plumbed to the "tee" fitting next to the oil filler. From there the hose goes to the air cleaner (just like my 2.0L). The oil filler has a PCV valve (check valve) on it with a hose connected. I need to know how this hose should be plumbed. On my 2.0L it is connected to a nipple on the intake plenum. On the 72 1.7 it is tee'd (using a copper plumbing tee with pipes solder into it) into the charcoal canister hose going to the air cleaner.
I think this hose should be connected to the intake so fumes can be drawn in and burned in the engine but there are no available nipples on the intake close to the size of the hose. The largest nipple (probably the right size) connects to the Warm up regulator with a 1 inch long hose with no room for a tee fitting. The next largest (probably too small) is the hose going to the MAP sensor.

With a PCV valve and this hose connected to the air cleaner it serves no purpose since with out some suction nothing will pass the PCV valve.

My 71 1.7 does not have the vents in the heads and only has a fitting on the oil filler, no PCV valve.

Where should this hose connect?

Thanks
