I have the privilege of sitting besides a car expert (Robert). He has driven his Toyota Camry for over 600,000 miles. He fixes everything by himself, thus saving thousands of dollars.

Today one other colleague came to him and told about his Honda that stalled on the road with a check engine light on. He had taken it to the Honda service. And they reported that the Radiator and engine gasket need to be replaced.

Then Robert was mentioning a very easy check to see and confirm that the gasket was indeed the problem. He suggested checking the oil cap and if you notice Vaseline like creamy coating on the cap, then it might be a gasket leak. This is formed because the coolant leaks and mixes with the oil.
