The procedure for servicing and repairing crankcase ventilation tubes starts by unconnecting the quick connect coupling at throttle body inlet tube and the quick connect coupling at LH valve cover fitting. The second stage of the process requires removal of the RH crankcase ventilation tube through disconnecting its quick connect couplings at the throttle body adapter and positive crankcase ventilation valve. Installation requires performing both the reverse order of removal steps for these crankcase ventilation tubes on right-hand and left-hand sides.
