hi phil focus

my problem started after i could smell burning oil on the manifold, i am only guessing but thought that the engine has to much pressure and forcing oil from weakest point?? yes my rocker cover is plastic, have you looked on e bay as they had 1 a while ago for 30 quid....

i might try putting gasket sealer then the gasket??

the thing is the car runs smoothly,idel's fine engine quite and temp gauge never goes past the middle, but engine does get hot. i dont want to take it to a garage and they say its 1 thing cost loads then it still does it andd then they say it could be ?????
