![]() ![]() Imagine the foam off of cappuccino and it's in your valve cover. Oil that has been contaminated with coolant will foam up. This presents a problem when your head gasket blows, as it can lead to both your oil and coolant mixing in different ways. Your engine oil serves a very important process and, if it stops working, it can lead to grinding pistons and various other complications. Discoloration may not be common, but it's a surefire sign that this component has failed and things are mixing where they shouldn't be. Your head gasket's job is to stop fluids in your engine from mixing. One of the more subtle signs of a blown head gasket is discolored fluid. What this means, you may have guessed, is that the cylinder has started leaking into your cooling system. Your leak may be more or less severe and, depending on this, it's not uncommon to find bubbles in your overflow tank. When oil leaks into your coolant system, it slows its ability to cool your engine off, with the result being your engine rapidly overheating. Overheating is never a good sign, but it is specifically one of the indicators that a head gasket has blown. This residue builds up in your combustion chamber, where it can lead to problems, later on. As it burns, the smoke it creates is thick and unpleasant, but the oil itself actually leaves behind a residue, as well. Oil doesn't burn as cleanly as fuel, which is one of the reasons why we use gas to power our cars and not most oils. Oil leaks out into the combustion chamber, as mentioned, creating a very noticeable smoke. Thick, smokey car exhaust fumes are caused when the head gasket breaks or wears out next to the oil system. Smoke is a big warning sign that should raise warning flags when you notice it. When oil leaks from where it's lubricating pistons and into the actual combustion chamber, it's time to bring the vehicle in for some repair work. Blue smoke may indicate head gasket failure and that your engine is burning oil. White exhaust smoke isn't the only warning sign of a blown head gasket. The costs of waiting out this issue until it "gets really serious", however, vastly outweigh what you're likely to pay. When it comes to expenses, blown head gasket repair costs can seem intimidating to somebody just realizing they need this work done. It's with this in mind that white exhaust fumes are an indicator of a head gasket fail. Your car is running through a series of high-powered startup operations, and your cylinders in particular need cooling. Startup Troublesĭuring the startup process, keep an eye out for white exhaust smoke. Especially in cases where there's a breach between two cylinders on the same head, you're going to want to look into blown head gasket repair.Ĭylinder compression and leak testing are great for localizing leaks so you can examine them during disassembly. The cylinder is literally the chamber in which gasoline burns and turns into the power that powers your car. Malfunctioning CylindersĪ misfire with your cylinders is another sign that your head gasket may have failed. These leaks are a sign of head gasket failure and a good sign you need to have any potential cracks and cylinder head twists looked at, immediately. In the case of a blown head, external oil or coolant will leak out from the seams between the engine block and the cylinder head. Your car's fluids are meant to be a closed system, so losing anything more than air conditioning condensation can be a telltale sign. With car repair, there is one warning you can always count on to mean something, and that's a leak. Here are eight of the most common signs that the head gasket is broken. Signs of blown head gaskets can be subtle. So how do we tell if we've blown a head gasket? What are the warning signs of a blown head gasket that tells us to drop everything and get the car looked at? Join us, today, as we find out. This could be due to misuse or neglect but often results from age and use. Like any other component in your vehicle, head gaskets can and will wear out over a long enough time. If you've ever looked into car maintenance and where your automotive risk factors lie, you'll understand why this is important. Using an airtight seal, it stops residue buildup in its tracks and keeps your engine free of things that might catch fire and explode. Its biggest job is to stop any fluids from gaining access to each other and mixing with each other in ways they shouldn't. When it comes to your car's engine block, your head gasket is a little like the bouncer at a party. ![]()
