Oil Filter Bypass issue

Was changing my oil filter the other day and in the process, I noticed a spring and plunger laying on top of my filter. I am assuming that this is a bypass valve of some sort. Ford want's top dollar for a new unit. Will it hurt my engine to run this with out the bypass?
Thanks

If you run it like that, your oil (some of it anyway) will be bypassing the oil filter and not get filtered (not good on a HEUI engine such as this). The early trucks had the bypass valve parts (spring, fiber disk, and washer ... goes back in in that order) simply staked in place. This was also true for the oil pressure regulator valve parts (on the block side of the header adapter). The newer trucks got the updated header adapter with those valves retained with snap rings. Here's the part number for the updated header:

Oil Filter Header (updated snap ring retained bypass and regulator valves)
(Ford) F81Z-6881-BA

List price for it is $245.87, but you can get it for $121.70 at AutoNation Ford White Bear Lake (previously Tousley Ford), so don't let your local dealer rip you off (mine is horrendous). Cheers!
