    Is there a list of everything you should do when going this far in? The main R&R thread only lists 5 parts and 2 clips. Ideally for an RS7 or noted part differences. I'm planning on:
    Removing the oil screen
    Replacing the check valve
    PCV
    Piston Cooling Nozzle Control Valve N522
    Turbo Oil return lines (?)
    Turbo oil/coolant line o-rings
    All necessary gaskets (?)



    Oil separator/PCV - 079103542E
    Check Valve - 079103175C
    Piston Cooling Nozzle Valve - 079-115-243-C
    Valley cover gasket - 079103161Q
    Throttle body seal - 079145818
    Passnger intercooler gasket - 079129717K
    Drivers intercooler gasket - 079129717J
    2 x Bypass valve seal - 079145417B
    2 x Clamp - N90489801
    Clamp - N90409501
    1 x WHT001011 from JHM kit, water line seal, not sure where
    2 x Turbo Coolant Line O-Ring Kit - JHM
    2 x Turbo oil supply line o-ring at turbo - N91056801
    2 x Turbo oil supply line o-ring at engine - N90303801
    Right side turbo oil return hose - 079145743A
    Left side turbo oil return hose - 079145742C
    Clamp - N90409501
    G13 coolant

    Do I need any more gaskets or o-rings? I'm not sure what I need for coolant related o-rings; the JHM kit is just for the turbo side it looks like.

    that seems to be a thorough list.

    he only thing id suggest is replace the clamps with worm gear clamps. just make sure to use quality ones that wont loosen up over time.

    I called the dealer and he told me the piston cooling nozzle valve part number is 079-115-243-C, which ECS calls the Pressure Restriction Valve
