I noticed while looking under my hood that I have a small leak around the oil filter head where it attaches to the block. The oil cooler is here and I am wondering if this is a problem with the cooler gasket. Is this something I should address imediately or is it something I can wait on for a few thousand miles until I get home? I really dont want to deal with water in the oil, but dont really have every thing I need here in Iowa.
