Small vid about PCV

Either you are wrong or did not word this well. The system as pictured differs only in one way from some of the cars I've owned--My 69 383 RR for example, had the hose from the air filter bonnet to the breather, was on the DIRTY side of the filter. I don't even remember anymore, if the 6BBL 70 was on the clean side or the dirty side. The method pictured, is essentially how all OEMs were done for years

Yeah, I could be wrong on that. I haven’t done a PVC system like the OE’s do it in so long I forget exactly what they are doing.

IIRC, the idea of the PCV was to draw in fresh air, pull that air across through the engine and out the PCV and then back to the engine to be burned.

Im sure there are variations on that. I know I don’t do a PCV any more without using some sort of catch can between the PCV and carb. Some might be surprised what kind of crap goes through that system.
