I have about 60 oil filter brackets that I have swapped and a few laying around. Kept the RR back mount on. Less dry start. So for the separator I use a 99 bracket without a bypass check ball. It has the hole by the filter to mount still. I cut the tubes off and thread in brass hose nipples with thread sealer. Screw in an oil filter with some right stuff for no leak at the o-ring. Pcv line in and then to the in side. No Anti drain back valve in the filter. So now just change the filter maybe 1 every 6 months.
