changing oil pump relief valve spring

[PaulRV6]

I have a stock pump setup and was wondering if it is worth (or a good idea) to change the relief valve spring out to a longer one? I have numerous length springs from aftermarket oil pump kits that were not used. I presently have the stock spring in now but wondering about putting in one that is stiffer or more coils. What do ya think?

my own inclination would be to NOT mess with a bunch of springs randomly, when you don't know where they came from, or what application they were intended for, or what the spring pressure is.

Well I should have said that the springs are all colored and the instructions give an oil pressure relating to each color. I am not sure what the pressure is the instructions are referring to. I hope that explains a little better. Thanks

I like the 60 psi relief spring,,, that's high enough psi IMO; and, any more would put unnecessary stress on the oil pump "drive train."

Hi Paul,
I like the blue spring myself. When you change the spring, you will lose some oil from the pump. Sometimes the pump will lose prime. Here is what I do when changing springs.
Remove the top oil line from the oil cooler adapter at the radiator.
Put a small funnel into the line and slowly add 8-12 oz of oil and re-install the line. IMH this is the best way to reprime the pump.

You can do this!!! Take your oil spring plug ( cap, what ever it is call ) Drill and tap a .250 std. thread in the center. Use an allen head bolt, lets say .750--1.00 long, screw a nut on, use a small o-ring and you can adjust to what ever pressure you want. IMO 60 PSI is about RIGHT. Hot and cruising at, lets say, 2000 rpm. I/m Cheap!!

T/A Performance sells this exact thing Lee is talking about. I am going to run one on my new motor when it's done.
