S54 Constant Pressure Valve Kit (CPV)

Regular price $68.00 Sale

A common problem on the S54 engines, the CPV O-ring fails causing a slow oil leak on the passenger side of the engine that frequently resembles a rear main seal leak. Replacing the CPV with our included upgraded Viton O-ring ensures a long-term solution to this common problem. 

Our CPV Kit includes a brand new constant pressure valve and the special tool needed to access the valve behind the exhaust header. Without the tool, accessing the valve is extremely difficult due to the lack of space for a standard sized bit.
