Re: How to add a PCV Valve to a 1949 Packard

I had similar issues with fumes from the road draft tube permeating the cabin at startup, when stuck in traffic, etc.

My solution was to extend the tube to the rear of the car, ending just past the differential.

I had my mechanic modify the road draft tube by creating an angled flange and welding it onto the tube's bottom end. He then fitted flexible aluminum conduit onto the flange and ran the conduit through the Packard's frame back to the rear axle. The conduit is secured in place with cable ties and there's a heatproof gasket where the conduit is hose-clamped to the flange.

I realize this is not an elegant solution. However, it resulted in noticeable fume reduction inside the car without affecting engine performance in any way.
