I was using a flapper delete fitting that leaked oil, even with a thicker o-ring. So I got rid of the flapper delete and got me a 1" flexible hose and a 1" to 3/4" reducer so it can fit on the BMS OCC. Problem solved.

Mine has been an annoying little thorn I keep putting off get it sorted out better.

My catch can is to the left so the tight radius bend with such a large hose has been a pain.

As an update, this double oring fitting never leaked a drop. Will run directly to intake pipe(somehow). Pcv port will be plugged with the stock fitting or perhaps a vta filter of some kind to relieve any potential crank case pressure that didn't get sucked into the intake.

Oil got past the first oring, probably because it can be wiggled around a bit but the second oring was visibly dry.
