Looking out for warning signs that show the head gasket is not functioning correctly. If it is already blown, a replacement or repair is necessary as soon as possible.<\/strong><\/p>\n\n\n\n Over time, the head gasket is subject to wear and tear, which can lead to head gasket problems. A blown head gasket means that the gasket has a break in it, even if it is very small, and oil, coolant, and gases can mix or leak out. As a result, the engine can malfunction, and its power can be reduced. To prevent this from happening, you need to know how to test for a bad head gasket.<\/p>\n\n\n\n In most of the steps that will be mentioned below, you will not need tools<\/a> as most of the signs are visual. Nonetheless, if there are materials that may be needed, here are what you should prepare:<\/p>\n\n\n\n When testing if the gasket is blown, it is important to determine if it is really the head gasket or something else. If so, a replacement gasket is necessary. If the tests reveal that the head gasket is not bad, you need to proceed with the diagnosis of the other parts until you are able to determine the source of the issue.<\/p>\n\n\n\n Before proceeding, watch this short video below for a primer on the next steps outlined in the article.<\/p>\n\n\n\n However, take note that this is only a preliminary procedure. Even if the engine oil<\/a> seems fine, the head gasket could still have a hole in it. To be sure if there is a problem with a bad gasket, continue with the other tests that will be briefly tackled below.<\/p>\n\n\n\n The next thing that you have to check is the coolant<\/a>. You may see oil in the coolant<\/a>, and it can sometimes be a bad head gasket or a couple of other issues. <\/p>\n\n\n\n Specifically, you have to look for the presence of hydrocarbons, which means that there are unburned fuel gases in the coolant. If you have these gases in any cooling system, you can detect them with the use of a to find their way there unless there is a broken head gasket.<\/p>\n\n\n\n AD<\/p>\n\n\n\n The best way to check for the presence of hydrocarbons and unburned fuel is through the use of a gas analyzer<\/strong>, which has been shown in the video posted above.<\/p>\n\n\n\n An external leak from the coolant is also indicative of the problem. Watch out for signs of leaks along the surface of the head gasket.<\/p>\n\n\n\n When testing for a bad gasket, you also have to look at the radiator and check if there are bubbles. To confirm if there are air bubbles, remove the cap that covers the radiator after the engine has cooled for at least 30 minutes.<\/p>\n\n\n\n Start the engine and rev it a few times. If bubbles are forming, this may indicate that your head gasket is leaking gases and is broken somewhere.<\/p>\n\n\n\n Another sign that you have a bad head gasket is when you have colored tinted spark plugs. Usually, you will notice that there are white deposits surrounding<\/a> the spark plugs. This is a result of the burning of the coolant in the combustion chamber. <\/p>\n\n\n\n If you use a green coolant and if you see greenish particles in the head gasket, take this as another indication of a head gasket problem.<\/p>\n\n\n\n The engine will not function properly if the head gasket is blown. One of the problems that will likely occur is an overheating engine<\/a>. This is because the engine is not able to receive the right amount of coolant<\/a>. A bad head gasket can also cause overheating during the combustion process.<\/p>\n\n\n\n This is one of the tests that you can perform to determine if there is a problem with the head gasket. The failure of the head gasket can cause low compression and misfire in the cylinders.<\/p>\n\n\n\n To perform a compression test<\/a>, remove the spark plug(s) and use a compression tester (Video).<\/a> If it shows low pressure in the cylinders, you may have a problem with the head gasket.<\/p>\n\n\n\n Below are some tips to keep in mind when dealing with head gaskets, not just when testing if it is bad but also when it comes to care and maintenance:<\/p>\n\n\n\n The video below shows one last alternative to check for a blown head gasket.<\/p>\n\n\n\n
