Oil filter block plate

I didn't use the little one either. Didn't see a need AND seems to me like it could cause a sealing issue with the outer main gasket. I wanted the filter adapter to pull the plate in nice and tight to the block.
Yes.... if were to leak between the plate and block around the center hole, where would the leakage go? It would have to somehow go past the threads in the block from the pressure side to the outlet side. Seal the nipple threads in the block and the small gasket is not necessary.

Boy this thread is OLD LOL
