I've also been reading all the threads concerning PCV and I'm a little stumped.

I am absolutely, positively sure the PC valve and my breather/oil filler cap, which also has the hose to the base of the air cleaner, are both on the driver's side valve cover of my '65 289. The engine parts aren't here for me to check. All the threads I've read seem to indicate the breather should be on the other valve cover from the PC valve. Does it matter?

Also, should I hook the hose back up to the base of the air cleaner from the oil filler cap or get a hoseless breather?

It dosen't matter which which valvecover has the PVC in it, but I've never seen one in the driver's side... It would seem to me that the breather should be opposite the PCV. The point of the system is crankcase ventilation/evacuation... if both were in the same valvecover, I'd think the PCV could simply be drawing atmosphere thru that valvecover via the open element breather... anyone agree/disagree?

I run a hoseless breather myself... un-clutters the look of the motor some

Dead head,
On '65 and '66 289s, the breather normally is not hooked up to the base of air filter or base of the carb. The breather is normally on the drivers side valve cover at the front of the engine. The PCV valve is normally on the passenger side valve cover closest to the fire wall and is hooked up via a hose to the base of the carb.

Deadhead,
All early Mustangs equipped with a PCV had it mounted in the passenger side valve cover. Some of the California cars had a breather cap with a hose to the air cleaner. The breather was mounted in the driverside valve cover. BTW, the breather cap with a hose was butt ugly.
