1. Remove crankcase vent filter on side of block and install a block off plate.

2. Find later model valley cover that has the road draft tube behind the carburetor.

3. Remove tube and install PCV valve of appropriate size for the engine displacement where the road draft tube exited the valley cover. You may need to construct a baffle for the valve to keep it from sucking oil.

4. Connect the PCV valve to manifold vacuum at the carburetor. You may need an adapter for this if the carb has no provision for manifold vacuum.

5.Bob's your uncle. You might need to enrich the carb slightly to compensate for the controlled vacuum leak the PCV creates.
