6.2l denali 1500

There isn't one.  The hose off the back of the drivers side valve cover that feeds into the intake manifold is where it would be.  Back in 03/04 the did away with the valve and replaced it with a fixed orifice that is just a sized nipple pressed into the valve cover.

 

Its non serviceable and there is no valve to change.

Call a dealer parts department with your VIN number.

I called about mine.

My 2012 5.3L the PCV valve is built into the valve cover.

Have to buy a valve cover to replace the PCV on mine is what they said.

 

Maybe Sierra HD17 is right and I got bad info.

They changed the valve cover orifice in 10/11 in an effort to avoid sucking so much oil into the intake (part of the AFM oil usage problem).

So is there a hose or anything to replace? I have some oil at rhr back of the motor and heard a bad pcv valve might create pressure and make it leak? Doesnt really make sense to me.

Correct.  Should never arise as an issue on a 6.2 without afm in it.  The design has changed since 03 slightly but there is no valve regardless.

 

OP wise you can replace the hose but see where your leak is coming from.  Maybe it's just a bad connection from where the hose clips in the nipple on the valve cover.
