Valley Plate with Breather Gen IV LS Machined Finish
From LS Classic
LS Classic Series Gen IV Breather Valley Plates incorporate a high efficiency breather assembly and port for superior crankcase ventilation. Precision CNC-machined from 3/8” billet aluminum, the plates replace the stock cast aluminum 11 bolt valley pans on late model, Gen IV LS engines.
Integral O-ring bosses on the bottom side of the valley plate blocks off the Displacement on Demand passages (No other DOD delete kit is necessary). Installation requires relocation of the oil pressure sender (a remote mount is included).
The valley plates are available with a cast finish and include all of the necessary O-rings, seals, and stainless steel fasteners. Breather valley plates have NO provision for oil filling.
