Re: Volvo D3 110 Sea Water Pump - Cover seal

Like Bill R suggests...  but also, look VERY closely at the smooth surface that the O-ring seals against.  A scratch there can make it impossible to get a good seal.  Anything you can feel with your fingernail is going to be a problem.

If you have scratches or other flaws, a very light addition of RTV gasket compound can fix it in the short run until a new smooth metal part can be obtained.  Too much RTV here can really cause issues with the pump.
