In the second category, the head gasket problem will cause the engine to overheat as it runs.

The first test we're gonna' do is to check the color of the engine oil sticking to the engine oil dipstick.
If the head gasket is blown, you'll notice that the engine oil will be the color of 'coffeee with too much creamer'.

Pull out the engine oil dipstick.
What color is the engine oil on the dipstick?
1.) The engine oil is the color of 'coffee with too much creamer'.
2.) The engine oil will be its usual normal color.
Let's examine your test results:
