As aboe , got my rocker cover powdercoated and ive not had the car that long really , but previously on removing it , i was shocked to see no gasket fitted

Anyway fitted new gasket on fittting rocker cover , and my problem is , where number 4 spark plug is (at back of engine) is filing with oil ? like the 4 areas around it if you know what i mean car runs fine and has done for the last week and a half that its been back on road ~?

Took of rocker cover and cleaned oil up and took plug out gave a check and im ready to put rocker cover back on now ?

Any ideas ? the gaskets still in place and to me looks ok ? it is a new gasket from woodford


any tips or ideas people ?
