1. Inspect the coolant liquid
When the engine cold removes the oil filler cap to inspect to get a milky brown liquid that is accumulated on the bottom of the cap. This is a sign that coolant has been leaking into the oil. This leakage could be generated by a cylinder head cube or leaking manifold in some cases although this situation the head gasket is more prone to this kind of failure.
2. Check the spark plug holes
Head gaskets are designed to restrain engine coolant in and around the engine block and cylinder heads. If they fail they can cause a flow that can be located by eliminating all of the spark plugs cranking over the engine while watching the spark plug holes and pressurizing the system. If coolant is current at any of the holes the head gasket is blown, it’s a great idea to disable the ignition or fuel system views before testing to avoid fire.
3. Open the radiator cap, check bubbles and liquid
While the engine is cool remove the radiator cap and when a head gasket has failed it’s allowing combustion gases. They can be detected by getting rid of the cap while the motor is running you ought to see a flow of bubbles and observing liquid.
4. Check exhaust gases in the cooling system
Verify exhaust gases within the cooling system using a chemical tester through a small amount of coolant in the radiator as to not contaminate the evaluation. This is exactly what a block analyzing fluid looks like it is available at any auto parts store or Amazon or eBay.
When the coolant has been drained down slightly add the test tube and insert the test fluid to the fill line, next start the engine when using the hand pump to draw air inside the radiator through the tester while testing the radiator air the test fluid will turn yellowish. Whether there are exhaust gases or remain blue, this shows the opposite.
5. Carried out a compression test
A head gasket can fail involving cylinders causing a constant two-cylinder misfire. You need to remove each cylinder spark plugs while running compression tests to check for this condition. This is sometimes a symptom of a failure between those cylinders if two readings are consistently low in neighboring cylinders.
6. Engine leak inspection
Some engines are designed with oil pressure passing through the engine block and into the cylinder head through the gasket. After the gasket fails it can cause an engine leak that is detectable by inspection carefully.
