[DML] Re: Overheating, idle speed and stalling issues



If this didn't happen before you worked on your cooling system, the chances it is a head gasket are small. Unless you didn't realize it with all of the other cooling leaks. Check in the oil fill and see if the plastic screen is still there and if it is melted. If it is there and NOT melted that means it is even less a chance of a head gasket as the source of the problem. I hesitate to suggest Magic in a Bottle to "fix" a leaking head gasket. I HAVE used Barr's Stop Leak but only to temporarily stop coolant leaks such as a leaky radiator. Much harder to stop a leaky head gasket, much higher pressures, WAY more than 15 psi. Doing a test for combustion gases is non-invasive and not expensive so it can be worth going for it. Before doing that you can pressurize the cooling system and check for leaks. Pull the spark plugs and see if you get any coolant into the cylinders. If you pressurize and lose coolant, it is going SOMEWHERE! Check the oil level in the crankcase too. If it goes up you have a leaky liner seal.
