I see where the preferred method is to block off the Road Draft tube and drill a hole in the lifter valley cover...if you didn't feel like taking off the intake and lifter valley cover is it possible to remove the road draft tube and fabricate a cover (you would have done that anyway) with an elbow sticking up and run a grommet and PCV in that? Would it suck in oil when you went around a corner?
Just curious.

If you are talking about the road draft tube located at the lower left side of the block, then using that block opening for a PCV valve is not recommended. There's too much oil splash at that location as well as being too low on the engine. The best location for a PCV is at the top of the engine where cold start moisture and contaminants will tend to gather. Here are past links to discussions about PCV valves. Blocking off the road draft tube Crankcase evacuation Finned valley pan and PCV valve installation Header evacuation system Installation of PCV valve into the top of the block Installation of PCV valve at top and rear of block 2 Modifying valve covers for PCV valve installation Valley pan PCV valve install 1 Valley pan PCV valve install 2 Valley pan PCV valve install 3 Valve cover baffle for PCV valve Why a PCV valve or system? Why the PCV must be at the top
