High oil pressure

Just an update changed spring in oil pressure relief valve and now running at 27 psi which is correct to the book , strangely thou the book states that the free length of the spring should be 68mm , the one I took out measured 45mm & the one I put in from land rover measured 55mm .

Not just length, also spring steel diameter and sping poundage, maybe previos owner used what he had or simply made a mistake with the parts?

I replaced mine when I rebuilt the engine. Original was very short, can't remember the length off the top of my head but it is probably in my engine rebuild thread somewhere. The replacement was a Land Rover branded one from Turners. When I went back in, about twenty odd thousand miles later, the new one was a lot shorter than when it went in too.

True. Spring was larger diameter
