I have been getting oil laying in the vally pan after a run. can not figure out where its coming from. the pan is not cracked and has been changed 3 times. I use the felpro 1215, with the thin paper gaskets on either side of intake and RTV red on both ends and in all four corners. no oil shows on paper gaskets when removed. this is not a "film" or droplets, this is oil puddled in pan. clean it off, make a pass, check and its back. anyone seen this before?
