I have a recurring problem with my focus, I have recently changed the inlet manifold because a diagnostic revealed there was a problem with the egr valve. Two weeks later I have the same problem, oil is clogging the inlet manifold and hoses leading in and out of the intercooler. Can anyone help as when this happens the engine drops to idle speed and will not rev until restarted also the glow plug light flashes until I restart the engine.



Is there supposed to be some kind of filtration system in the inlet hose to the intercoooler ?
