The only true way (IMO) to fashion a
functioning FYB PCV SYSTEM without opening the rocker cover(s), is to use the OEM setup as was used on the 1961-62 FORD/MERC PASS CAR (2V) or 1961-64 292 TRUCK (2V/4V) The 4V is preferable but the 2V SYSTEM can be modified.
The shield under the rear of the valley cover is a
SPLASH SHIELD designed to deflect oil splash from the DIST DRIVE. This will not prevent ingestion of fumes/mist into the PCV SYSTEM. The bell shaped adapter (baffle) is designed to do that along with the long metal cooling tube (allows vapor(s) to cool and drop back down.
The front baffle on the valley pan is also needed to direct ventilation draw to the rocker arm areas.
These setups shouldn't be that hard to find as farmers are still using old trucks or have then sitting in the yard.
CASCO advertises being able to modify and early pan to PCV/late ROAD DRAFT. Have no idea of the quality.
