Looks like my Ka (1.3 pushrod / Endura-E / kent / sewing machine gone badly wrong engine), is leaking oil from the rocker cover gasket.
It's had a new gasket a few weeks ago, so I should be able to rule that out. It is leaking in the same place as before (could be cack on the head / rocker cover stopping a good seal perhaps?), the bottom right corner as you look down on the engine from the front of the car.
Could the leak be caused by blockages in the oil cap breather pipes or some such? What exactly do these do? Is the rocker cover at positive pressure compared to the atmosphere?
TIA for any ideas.
