Hi Sunshine

The oil seems OK. How low was the coolant level? You can get by for a while with water only but make sure you get some antifreeze (in my area it is mixed 50/50 due to winter conditions) in the proper ratio for your area.

Check for any drips/spray/leaks under your car while the engine is running, also check under the hood for any leaks....keep your hands away from moving parts ....just do a visual inspection.

Sometimes a head gasket leak will show up as bubbles in the radiator, but not always. We're just gonna hope that is not the problem.

Do you know the engine size? If it is a 4.6 Litre you might have an intake manifold problem....they are prone to failure (cracking). You said something about residue near where you put the oil in?

Let us know what's happening.
