Recommendations / InstructionsThe oil is pushed up the left gallery in the Lyc from the pump and filter, travels across the front of the engine, and then down the right side. Crossdrillings through the bearing webs take it to the cam and crank bearings. The older small Continentals do that, too. This puts the pressure relief valve at the end of the run.

The oil pump maintains oil pressure to lubricate internal components. Most oil pumps are positive displacement pumps, which deliver more oil than an engine needs. To address this, there’s a pressure relief valve located at the oil pump outlet. Its purpose is to open when engine oil pressure reaches a certain value. A problem with The oil pump pressure relief valve is located at the front of the engine and is accessed via a blind nut on the side of the unit. The bolt is in the form of a cap, which when removed can be seen to be holding down under tension a spring, which in turn presses the valve.The dual oil pressure relief valve cases separate the two functions. The 1st valve (pulley end) still controls whether the oil goes to the cooler or not. The 2nd valve (flywheel end) regulates the oil pressure after it has gone past all of the rest of the engine's needs. This was necessary when they made the oil galleries larger in the block so ...Don't be surprised if the new pump parts don't restore the pressure as high as you would like to see it if the rod and main bearing clearences are greater from wear. If the pump can't keep up with the flow rate, the relief valve will never open except when the oil is cold before warm up or heavier oil is used.
