im working on a 97 and its leaking out of the oil pan plug is there saposed to be an O-ring on this plug or is it saposed to be one of the neopreme seals? not familiar with these 12 v problems so it may be a no brainer im just missing somthing here

 

Im pretty sure there is supposed to be a seal on the plug... But Im not sure. Also those plugs can brake at the shoulder causing a leak, You can buy a better built one at Genosgarage...
