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

If that screen is not melted it is doubtful the motor overheated to the point where the head gaskets are damaged. The coolant pressure test will be more telling. If the leak is under the intake manifold it will be hard to see but you will see the pressure and the level drop. If you do not see it going into the crankcase (by the oil level getting higher on the dipstick) and you don't see it pissing onto the ground, the only other place it can be leaking (if it isn't going into a cylinder) is under the intake manifold. It can take quite a while before all of those cavities fill up and start running over. If you have a fiberscope you can stick it under and see.

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.
