It's simlar to your design, but with a little design difference.

Under heavy loads, case pressure in excess of the limits of the PCV will force oil vapor through a 5/8" hose, into the filter. The bronze wool helps trap the oil droplets and allow gasses to vent. But with the opening on the bottom, oil can automatically return to the crankcase when crankcase pressure is normal and the PCV is operational again. With the filter unit mounted at the correct height, the slight vacuum in the PCV system will draw oil back to the crankcase. Any additional air entering the case will be filtered by the wet bronze wool (steel will rust out). The whole mess cost me less than ten bucks, and temporarily solved the blowby oil loss and subsequent smoke. Obviously, ,the best long-term solution is new rings, but if you're planning to trade it in...

I'll bet the dealer mechanics were scratching their heads over that "AC" CCV Filter... The custom label was a nice added touch, so it looked like it belonged there.

Go to your local building supplier. Get a 4" black polyethelyne cap made for corrugated poly drain hose (the type used for landscape drainage) and a 4" diameter drain interceptor. A second cap will work in place of the trap/interceptor, as long as you cut off the raised ridge. Cut ventillation slots in the upper cap, punch a hole for the grommet in the bottom, and install the hose connection (from an auto parts store HELP! section). Stuff it full of bronze wool as an oil resistant filter material, then glue the two halves together with PVC solvent cement. There's your filter/trap.

I mounted mine with a 4" plumbing riser standoff clamp, but anything that will hold it satisfactorily and not look like a complete Rube Goldberg job should do.

Mine went on an old Fiero that had no rings left just before I sold it to a used car dealer. The device stopped the oil pumping to the intake tract and resultant smoke. It couldn't have happend to a nicer guy...
