Is there supposed to be an o ring and a paper gasket between the oil filter adapter and block? In the fel pro oil pan set theres two different style paper gaskets and an o ring the size of the oil cooler seal in not sure what there for.

 

if it has a oil cooler, yes

 

Got to looking at it again and I dont really see where that thin round o ring would go, but I was pretty sure a gasket went in between there though. Mine does have the oil cooler.

 

There is an "O" ring that goes between the oil cooler and the block, looks just like the "O" ring on the oil filter, it may even be the same size and shape as the oil filter one but not for sure.
