The Pug leaks oil; it is all over the back of the engine, and drips onto the road. It leaks as a mist from where the crank breather pipe enters the inlet manifold, and also from the back of the rocker cover.
I have dismantled the breather pipes and none are blocked.
I am going to replace the air filter.
Is the plastic round shaped piece where the breather pipe is connected to the rocker cover a pressure release valve or a filter? I intend to replace it and also the 'O' ring seal where the crank breather pipe joins the inlet manifold.
If oil still leaks after I have replaced these items (and the rocker cover gasket) what could be the cause? Piston ring wear causing excessive blow-by/ crank case pressure?
I look forward to your top tips.
