The smoke looks and smells like an exhaust smoke from both places. It doesn't seem to me like steam as yesterday (with the engine only idling) I could not get to higher temp than 150°. But to be sure, can you advise the differences of smoke from oil, gasoline, other?
What does it mean exactly that 'the smoke and bubble situation may become worse'? What could happen?
To see how the engine is acting I will get me a rubber gasket to use it temporarily with the present expansion cap. Othervise the tank does not seal and the coolant is spitting out rihgt from the start of the engine.
How can I diagnose the bad head gasket? If the cooling is temporarily sealed and the head gasket is bad, the engine should overheat, no?
As I can not cruise with the car now, I have to simulate the load somehow. What is the RPM level that I should keep and for how long to see if the engine is overheating?
As for the heat riser valve, I will test it but I need to know more here. The shop manual says that the valve is closed when the engine is at normal operating temp and running at idle speed. Normal operating temp is arounrd 200°? If so, I have to make sure the engine firstly gets to that temp.
