Buick Adjustable Oil Pressure Regulator

Buick Adjustable Oil Pressure Regulator

It is best to maintain between 10 and 15 lbs of oil pressure for every 1000 rpm. If your pressure readings are on the low side, our Adjustable Oil Pressure Regulator may be just what you need.

This replaces the relief valve nut and spring next to the oil filter. Turning the adjuster screw in will increase oil pressure and backing out the screw will lower the pressure.  Recommended for any oil pump rebuild and much safer than using heavy weight (color coded) springs.

Fits the following Buick Engines:

198-215-225-231-252-300-340-350-400-430-455.

NOTE: Does not improve pressure at Idle, proper pump set up and our Booster Midplate 32-3001 will improve pressure at idle.
