The Oil Pressure Relief Valve is designed to limit the oil feed pressure at higher engine rpms, primarily to reduce excessive oil volume from being pumped to the top end. However, the factory-installed valve body does not have a concentric taper to seal on, and does not properly seal oil pressure when operating below the blow-off point (lower engine rpms). Baisley Performance’s Precision-Ground Oil Pressure Relief Valve has a concentric taper that is designed to seal the oil pressure below the blow-off point. This enhances and stabilizes the oil pressure at idle, and forces the oil to take the correct path to the critical areas of the engine; like the tappets, cam chain tensioners, piston cooling jets, and the top end.
The Oil Pressure Relief Valve is designed to seal on the seat of the cam plate pressure chamber. However, the factory-installed valve body does not have a concentric taper to seal on, and may not properly seal oil pressure when operating below the blow-off point (lower engine rpms). Baisley Performance’s Precision-Ground Oil Pressure Relief Valve has a concentric taper that is designed to reach into the seat to prevent leakage that can cause improper flow of oil to specific areas of the engine. When properly sealed on the pressure chamber seat with the proper spring pressure you may be able to increase oil flow to critical engine parts. Note- This is a professional use product that requires pressure testing to validate the results before installing this devise in the engine. Its not recommended to install this devise in an engine without testing results on a bench pressure test.
Baisley® Precision-Ground Bypass Plungers fit all Twin Cam® engines.
