How can I tell if my car has a blown head gasket?
In most cases, this also allows engine coolant to invade the cylinders. Inspecting the spark plugs for failure signs is a viable test for a blown head gasket. Remove the spark plugs from the engine using a 3/8-inch spark plug socket and ratchet.
Why do I have a leak in my head gasket?
Leaks are a manifestation of a bad gasket. These leaks are commonly seen in your spark plugs so it only makes sense for you to remove the spark plugs for inspection. Do this right by pressuring the cooling system once you’ve removed the spark plugs.
When to remove spark plugs for head gasket?
This test is not always reliable when detecting a head gasket. So it’s best to move on to other tests until you’ve exhausted all options. 2. The Spark Plug Test Leaks are a manifestation of a bad gasket. These leaks are commonly seen in your spark plugs so it only makes sense for you to remove the spark plugs for inspection.
How can I tell if my spark plugs are going bad?
Inspect each spark plug for failure signs. Dark sooting from misfiring, water droplets, brown spotting, and rust around the threads are all signs of head gasket failure. Inspect each of the spark plug boots. In some cases, where severe gasket failure has occurred, condensation and moisture will accumulate on the plug boots.
Can a blown head gasket be checked by spark plugs?
This expansion breaks the gasket seal and engine compression inside the cylinders then escapes, causing permanent damage to to the gasket. In most cases, this also allows engine coolant to invade the cylinders. Inspecting the spark plugs for failure signs is a viable test for a blown head gasket.

Why do you need a head gasket on an engine?
The head gasket prevents liquids and gases from escaping into adjacent cylinders and the surrounding oil and coolant galleries. Engine coolant surrounds each cylinder in order to maintain a stable operating temperature; it also needs to flow into the cylinder heads to cool the combustion chamber, valve and spark plugs.
Can a blown head gasket cause an oil leak?
Some engines are designed with oil pressure passing though the engine block and into the cylinder head along with engine coolant (each in separate ports) via the head gasket. When the gasket fails it can cause an engine oil or coolant leak which is detectable by inspection. If you have any questions about head gaskets please visit our forum.
This will make the engine overheat. To confirm exhaust gases inside the cooling system (gasket failure, cracked head or block) use a chemical tester which you can get from Amazon or the local parts store. Drain a small amount of coolant from the radiator as to not contaminate the test.
This means it’s fairly common for the following engine problems to be wrongly diagnosed as a blown or leaking head gasket. Coolant in the oil. Although head gasket failure is often blamed for coolant leaking into your oil, it may be due to problems with the intake gasket. Engine overheating
What happens to the coolant in a blown head gasket?
As a result, the coolant can enter the combustion chambers, where it is burned during engine operation. As was mentioned above, a blown head gasket can allow the coolant to be burned inside the engine.
Can a blown head gasket cause an engine misfire?
Therefore, a blown head gasket can result in a loss of compression and an engine misfire. In some instances, the oil and coolant passages can breach at the outer perimeter of the head gasket. When that happens, you’ll have an external coolant and/or oil leak coming from the engine.
How dangerous is a blown head gasket?
Aside from the damage it will do to your engine, driving with a blown head gasket can be dangerous. For starters, if you’re checking under the hood to identify the problem, hot escaping coolant can cause burns and even start a fire if you’re not careful.
What can you do if you have a blown head gasket?
5 Signs You Have a Blown Head Gasket (and How To Prevent It) Overheating. A head gasket failure may be caused by an engine overheating one too many times (as a result of a clogged radiator, coolant leak, faulty fan, etc.), but Loss of power. If the head gasket fails in such a way it allows the compressed air/fuel to escape, the compression of that cylinder is reduced. Oil contamination. One of the most famous signs of head gasket failure is the milky sludge on the underside of the oil filler cap or the dipstick, sometimes jokingly
What are signs of a blown head gasket?
Here’s a short list of customer complaints that are symptoms or signs of a blown head gasket: A strong, sweet smell of heated coolant. Low coolant level in the coolant reservoir, without visible leaks. Bubble formations in cooling system. Reduced power or problems with idling and acceleration.
How serious can a blown head gasket be?
Anyone who has had a broken or “blown” head gasket knows that it can cause some serious problems. Oil residue can build up in the combustion chambers, causing them to fail, and oil seeping into the coolant system causes a vehicle to overheat, causing even more damage. Not fixing a broken head gasket can lead to very costly repairs.
