Necessary to run oil filter bypass valve??

Ok, I have had an issue with my oil filter leaking upon start-up everytime recently and it still does it but this time it completely blew the oil seal out and made a HUGE mess. This has not been caused by double stacking the filter seals and I have never done that.
Anyway, I believe my issue was a possible sticking oil filter bypass valve and I want to know if I can run the engine without one. This truck is no longer a daily driver, strickly sled puller and will probably never see the street again. Will running no filter bypass valve affect oil pressure at all? I removed the oil cooler/filter housing to inspect everything and the bypass valve seemed to be operating properly but I took it out anyway. Apparently my oil pressure regulator and spring are working cuz they are not sticking, takes a good press of the finger to press the regulator but it works.
I change my oil and filter very fequently now that it is a sled puller and I highly doubt not running the bypass valve should hurt anything but I wanted to check with my fellow diesel heads first.
Thanks for the advice guys, hopefully I found the culprit of this ongoing problem I have been having.

Joe
