Mopar BigBlock 383 400 440 Oil Pump Adjustable Pressure Regulator USA Made M63HV

Description

Our new adjustable oil pressure relief valve is a great accessory for your big block Mopar. This unit simply screws in and replaces the original plug which holds in the oil pressure relief plunger and spring. This plug is drilled and tapped in the center with an adjusting screw which can be screwed in or out as desired. The screw is surrounded by a special liquid tight o-ring seal to eliminate leaks, and held in place by a nylon lock nut & washer.
Screwing the plug in will put more pressure on the relief spring and raise the oil pressure, while screwing the plug out will release the pressure on the spring, and cause the oil pressure to drop. You can use this to adjust your oil pressure where you like it (within a reasonable range), even while the engine is running! (Challenge your Chevy buddies to try that one!) Works great for offsetting pressure loss or gain from specific bearing clearances, certain oil viscosities, etc, etc. Works with ALL oil pumps including factory pumps, aftermarket Melling pumps and Racing style billet aluminum pumps.
