has anyone ever had to change the gasket for the oil filter flange on a 4.0 ohv? its under the passengers side header looks like a ****** to remove but autozone and orieleys dont have a gasket for it. i dont know but when its real cold itll leave me a basketball size pull of oil under it till it warms up and expands to seals itself. does any one know if you can do this with out taking off the header and whats the part number? not a big problem but management at my apartment is bit**n about the oil stains
