[Healeys] Oil Pressure Relief Valve Question

[Roger Grace]

Yes me too.
Changed out my oil pan gasket for a newer silicone one, and as that drain notch had not been cut out oil pressure went through the roof. Had to drop the pan again and make a notch.rg

David
I can add a similar problem to that which you identified where there were 100 sump gaskets on the market that did not a have a hole where the oil behind the valve could  get away resulting in the relief valve not operate correctly.
If the valve did not 'relief' then oil pressure could rise way above the safe reading. This could cause the pump to have to work harder and the stain on the pump, pump shaft and cam shaft could cause damage.
Best regards

The spring should fit into the hole in the plug and the valve. There is a bleed hole on the back side of the valve that drains back int the oil pan. It sit in the in debt of the oil pan. I have seen some alloy pans that block the hole. Also have seen people use excessive silicone and plu the hole up.

My recently rebuilt AH 3000 with new oil pump is putting out 100 psi of oil pressure at startup and is at an easy 50 to 60 psi at idle when heated up. It is my understanding that the oil pressure release valve is set to not exceed 60 psi? I pulled it out, and my question is, is the spring supposed to sit down inside the machined hole in the plug or is the spring supposed to sit on the lip of the plug and not go down into the hole.
