Anyone use a DF-17 adjustable PCV?
I have one and I don't think much of it. It should work but I think they made it too complicated so it is actually kind of hard to figure out. I ended up making a fixed orifice PCV which works just fine. A fixed orifice setup actually works really well with a big cam and it shouldn't require too much work to make one.
I read these posts with some Interest , I experimented w/ pcv`s and cover to air breather lines on my 505 , still dont understand all/much of it .
My engine definitly didnt like the cover to air cleaner hose with pcv on the other cover. , ACTED LIKE A VACUUM LEAK , which is interesting , cause I dont have any oil at the valvecover breathers when I tried them, even built an oil catch can ,nothing showed up in it . been running 2 pcv`s , now one on each cover , both are full intake fed /under the blades , which creates 6'' of crankcase vacuum. IT HAS 9-16 INCHES OF INTAKE VACUUM , depending on throttle opening . I tried a crankcase evac set up on the drivers side w/ the the pcv`s on the other side , dropped my crankcase vacuum to about 1 1/2'' .
I`m thinking of plugging the pcv`S off and running the crankcase evac at the strip only-------I dont have any engine oil leaks running the pcv valves and like that set up -------------all thots and comments appreciated ---bob

Incedently , I just put a 1/2'' spacer under the throttle body on the victor intake , seems to really like it , I`ve always thot the plenum on the victor was too small------???.
