Head-Mechanics

This is what cold sludge looks like. It forms when oil and water mix. it emulsifies and turns this cappuccino colour. you can see dark streaks i the cold sludge were the oil hasn't properly mixed. You can also see the cam followers and were the head bolts go.

The spark plugs are located here

This has to be the worst case of cold sludge I have witnessed. you can see that the sludge has peaked and turned stiff.

The cold sludge from this engine had worked its way to the air filter and the chambers of the inlet manifold were filled. The exhaust system was also covered with it. Please dont drive your car when you have a head gasket failure.

Your MGF should not smoke excessively from the exhaust:
