Hadn't seen more than a few post on PCV reroute for the L5P so I thought I'd share mine. Earlier gen hose required 5/8" hose it seems while the L5P uses 7/8" id.
I chose not to use the stock short section as the hose I used is very good quality and retains its form.











I have a breather filter to go on the end coming shortly to keep bugs out as well.
This is the hose I used.
Vibrant Performance Braided Flexible Race Hoses 11973

Cap on the intake is also 7/8" and HSP makes a high quality one that is on order so currently just using the standard Dorman until that comes in.

Looks clean. I am relatively new (less than 2 years) to the Duramax world, can this be accomplished with out a tune? I don't want any limp mode and check engine lights... I have a 2019 2500
Thanks

Yes has no effect on any monitored engine parameters.
