Good for you , thanks for the update

 

Does anyone know the part numbers for the PCV valve and hoses that are typically replaced? Im chasing down the gremlins now.

 

Can I fix this lean code p0174 with this repairs or it's completely something else ?

 

xfv8, a lot of what is posted here will work for the P0174 code too. You are just looking at bank 2 vice bank 1. But, they are both common before the intake splits it left and right. So, ou would be looking at the lower IMT valve as your most likely source of the problem, but anything listed above may be it too.
