Hi Art
I changed my oil pressure relief spring about 4 seasons ago, when the pressure
didn't come back up after an engine job. The old spring had rubbed against the
bore it rides in and had worn halfway thru the coils near the center.
It is unlikely that a relief spring would get hot enough in the engine to lose
its temper. Age, wear, and fatigue would be the culprits.
