I have had 440 steel cranks with the things in the other direction--can cause a headache--you can polish the area smooth and the rubber seal will do fine--that is a rare problem but have been there done that in the past--I bet it is some other problem back there--the newest Fel Pro supplied rubbers are a tad shorter and don't stick up from the seal holder enough--PIA! Put the seal holder on a rod cap cutter, knock 010 off it and make sure the seal is protruding--you will be fine
