On my 603 (1991 3.5L) the oil cooler line connection has an o ring at the filter canister. It’s looking like it’s starting to weep, is there anything to be concerned about in trying to fix this? I assume it’s just a matter of removing the two Allen bolts, pulling the line, and swapping the oring… but are there any other considerations to make?
