Re: Opinion on PCV valve for flathead?
36tbird>>>my plan is to run the tube from the PCV to the air cleaner and vent the crank case>>>
ford1>>>the problem with running the pcv to the air cleaner is that there is not enough vacuum>>>the one to the air cleaner works good at hiway speeds due to the extra suction by higher engine rpm's>>>
As Lou knows, I'm running a simple reverse-flow no-valve PCV. A tube filled with stainless steel mesh runs from the air-cleaner cannister to the oil-filler stand. A fine air filter screen is also wrapped several times around the crankcase vent to prevent road debris from entering the crankcase. The main purpose of the mesh-filled tube is to prevent backfires as well as catch entrained oil droplets. Lou says he's found a PCV valve that works on low air-cleaner vacuum that should also serve a similar purpose.
