Thread Topic: Fill/Drain Plug Seal - Washer or 'O' Ring? <br /> From angus63, 06/08/2005<br /><br />Three points:<br />1) if there is an undercut where the threaded portion meets the head, yuo need an o-ring.<br />2) No undercut you need a washer.<br />3) o-rings reusable after visual inspection, nylon washers must be replaced after intial torquing of the plug: "one time use".<br /><br />Since older LU sometimes have the plugs replaced due to worn slots, you'll need to check which kind you have before selecting a seal.<br /><br />Good luck
