I recently replace the timing chain and have been piecing everything back together as I get time; however, I haven't been running an oil cooler since I put in an F body radiator. Would I need this if it is the oil cooler adapter to timing cover seal?
Little known fix: Put that gasket where the O ring goes (between the oil cooler adapter and timing cover). The gasket will definitely stop the dreaded leak from that area. O rings don't really work there.
