This may seem like a "no brainier' to some of you but it's got me thinking. A friend of mine gave me two old but new oil filters that fit my Mountaineer. One of them AC Delco, has surface rust on the flange inside the seal area where the 6 holes and threaded center hole is. Not real bad but enough to concern me some. Now I don't know if the 6 holes around the center hole is pressure or return. If they are return then any rust particles will get picked up by the filter. If it's pressure they'll end up in the oil going to the engine. I'm torn between pitching the filter and using it. I hate to throw money away. Your thoughts?
