You can be very sure that was the first thing I did! Back seat too - only 2 bolts for that one.

pct valves. my approach is remove innards of pcv,run a hose to air cleaner inside the air cleaners no vacume is lost at carb. the  oil filler cover has a small vacume. only time I had blow by showing was when I had to much advance at idel. this works great for me as running a newer Holley 4v 680cfm.i set my low idel  like ted send using the idel screws on the primary.s use the fittings  at throttle plate is 2 on the newer  Holley. I use manifold vacume for power brakes, and vacume wipers
 only negative is fuel hear in bc for the summer badger the thought that ethenall is going to save the world. no one in canada speaks out  that fuel consumption goes up,a
 with  the bad fuel,aswell engine keeps running when ion. turned off.

The Microgard pcv 2322 fits the Ace valley cover. Thanks, Ted.
