I took the valve cover off to set the valves on my 3.3 Cresta engine today now everthing has settled down and was suprised that the top of the cover had a thick coating of emulsified oil, the engine oil is still clean I changed it 2 weeks ago but for the first couple of weeks I used 15/40 diesel multigrade to flush the engine out as it had been stood for a long time .
Could it be the 15/40 oil that caused it as its a detergent oil or just that its been so damp recently and the engine as hardly had chance to warm up, there are no other signs of the head gasket leaking , I am now using 20/50 and apart from a slight misfire midrange the car is now running great , no overheating , the spark plugs are clean and all the same colour .
