Gm white spring question...
It only raises the maximum pressure allowed from around 60# to about 75# from my experience. Others may claim slightly different numbers but on average, it makes about 10-15# more than stock.
I am also convinced that the whit spring is frigging up my oil pressure senders. They start sticking after WOT blasts and now I am on my 3rd one in 2 years.

Some of you should look into how the oil pump functions and exactly what the spring does.
If a higher pressure spring raises idle oil pressure then the relief valve was sticking partially open or there was some other PROBLEM.
Competent folks have no trouble with the "white" spring messing up senders. When reading forums you have to understand there are a lot of incompetent folks claiming good parts are bad and bad parts are good. They are if anything the majority. Good luck weeding them out so you can ignore them appropriately.

Once your done gazing into the mirror and proclaiming your competence and superior intellect, you can tell me how many ways a oil pressure sender be installed right or wrong or even better help the OP out? Either provide substance or get the **** out.

The spring determines the maximum oil pressure.
When pressure reaches the 'setpoint' oil bypasses the pump and oil pressure drops. I have a high volume high pressure pump, at idle and at temp the spring has no effect because the pressure is below the setpoint. BTW to use a hv pump you need a larger pan.
Good luck

Simple as the name implies "RELIEF spring", as the last poster said it RELIEVES pressure above the set point of the spring. It is a little plunger within the pump base that compresses the spring, once the spring is compressed enough by sufficient pressure it uncovers a bypass port dumping the oil back to the pickup.
I had a really good link but I can't find it now, maybe someone else has a good link on how a positive displacement pump functions and why we look at pressure when FLOW is what actually matters.
FWIW I have put the white spring in about 4-5 motors, only oil pressure sender I ever had fail was one on a junkyard motor BEFORE I ever replaced the spring, I believe the elements got into it because it failed moments after I started the motor for the first time.
I wont claim it to be an oiling fix all but what it does do is allows you to use the pumped volume of the stock [pump to a little higher rpm and replaces an old possibly worn stock spring.
The oil pump is really amazingly simple and reliable once you understand it.
