what problems should I look for

I would look for a crack in the adapter plate  (mine cracked after years of over tightened oil filters) or make sure the gasket between the adapter plate & block is good. Look for tears or a misaligned gasket. Good luck! 



I love the smell of burning rubber in the morning!

One other thing to check.
This is from the Walt Nuckels Homepage located here:

Image of oil filter adapter from Y Block engine being reformed so it will seal tighter against the gasket


When placed on a flat surface the center hole should be up about 1/16" from surface so that when it is secured in place much force will be exerted upon the gasket

Tip ; Use contact cement to glue the o ring to the plate before offering it up to the block.
