bypass blower valves

[BusNit]

What difference would a valve with a stiffer spring do to an otherwise stock 8v92? I had found one on eBay (black one in pic) which has a much stiffer spring than the one that came on my bus. I have been cleaning up small oil seeps/leaks and this valve had some minor oil seepage. Should I put mine back in or go with the stiffer spring one?

Clean yours if slides easy it is ok the 23508370s is used by the military for other things besides a blower, I never saw one on a 8v92 before

Thanks Cliff. Figured it was something to that effect.
