Just wondering if the relief valve is accessible without pulling the timing cover or the whole engine. New problem I'm having is that after exiting the highway and oil is hot, when you stop at the intersections the oil drops low enough to trigger the warning light. I understand the light is preset for either 10 or 15 psi. There are no noises or metal that I can see in the filter. I'm probably going to get a block and start doing a buildup of a new engine soon, but in the meantime I'd like this to survive and make more pressure. On my older Pontiac engines I was able to pull the oil pan and add a couple washers to the spring on the oil relief valve to pick up more pressure. Same on some of the airplane engines I work on.
Looking at pics of the oil pumps, it almost looks like there's a relief spring nut on the outside of the pump, same side as the filter housing.
