PCV always has 3/8" line directly to its own port on the intake mani,

OE had the (sucking end of) PCV sitting in one leg of a fat molded rubber 'Tee',
the bottom of the tee attached to the valve cover,
and the second leg of the tee going to the airbox
(for PCV action during boosted operation)

lol these 'Tees' are usually hard, brittle, cracked and leaking,
or missing and replaced by some PO bodge...

PCV Valve is a check/metering valve.
+1 they are internally 'sized' differently too,
so the wrong PCV valve could let too much air through, behave like a vacuum leak

so, make sure you have the right one for your application.

anyone have suggestions on brands to use/avoid ?
I think I'm running a 'Standard'..
is this still available from ChryCo ?
