I have the good old oil around the spark plugs on my 95' 16v clio, so have been told its the rocker cover/cam cover gasket needs replacing. Sorry im a bit stupid when it comes to mechanics (trying to learn), is the cam cover gasket and rocker cover gasket the same thing? Also can anyone tell me the best place to buy one? I cant find them on GSF website which is ennoying me as I've read others have bought them from here! thanks in advance, Sam
