Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Workshop Note - GDI Oil Breather

Mine has done a couple of thousand miles with the breathers venting to air, and so far no light. Even when I put Seafoam through the inlet tract and created a battleship worthy smokescreen, it was OK. Which was surprising. The cam cover breather feeds in just ahead of the throttle body, so blanking that off and venting to air shouldn't make any difference, and in fact after regular inspections, this breather stayed spotless inside. The crank case breather will pulse oil fumes into the inlet manifold, and that seems to be the source of the oil deposits. Because the air/fuel mixture is already set when it enters the inlet manifold, blocking the breather hole in the manifold and venting to air shouldn't make any difference to running either.
