    Anyone know what year GM started using the new fixed orifice PCV valve? I think the part number is 12572717? Is it worth installing? I have a 2002 2500hd 6.0 gasser...

    Generally by '03 they had the fixed orifice valves in them. And your p/n is correct.

    Pop your old one out and see if its the older style...if so, order up the updated FO.
