Since I have a valve stem leak at cylinder #7 and various other spots, I'm looking for a longer oil filter for the 4.7L engine for more oil capacity.

Does one exist? Thanks

 

Oil filter will not give you any more capacity, i mean yea the filter might hold another cup of oil but its not much. Better off to fix the leaks and the valve stem seals, plus even the extra capaicty of the filter wont help you, it will always be in the filter
