No. The high pressure spring holds the release valve more and allows more pressure to build up. It's an old trick to pull the oil spring out, stretch it and put it back.
This is my reasoning on it.
Lets say the oil pump puts out 5 gallons a min max.
But worn bearings allow a 6 gallon per min flow.
I don't understand how a tighter spring is going to make the oil pressure compensate for a 6 gallon loss through the bearings if the oil pump can only do 5 gal a min anyway.
I always thought the spring was to relieve to high of a pressure and had zero effect at Idle RPM's unless cold oil was just to thick to pump through the bearings at 5 gallons per min.
