What is a Cylinder Head Gasket?

The cylinder caput gasket might be the most important role of your auto that you've never heard of. There are two major responsibilities for the cylinder head gasket, and it'southward pretty good at multitasking. The gasket serves to form a very tight seal between the engine block and the cylinder head. That seals off the combustion bedroom and keeps the oil and coolant passages in the cylinder head separated. That might not sound like much, only it is. Without the cylinder head gasket to do those things, your car'south engine won't role properly, and will be liable to suffer serious damage. You don't want that. Cylinder head gaskets unremarkably accept a long lifespan, but they can occasionally die. Given their job and their location, they're subject to a lot of wearable and tear, besides as farthermost temperatures and pressure. That can eventually lead the cylinder head gaskets to die, at which bespeak they'll need to exist replaced.

Symptoms of a busted Cylinder Head Gasket

Bank check engine alarm lite

The check engine calorie-free exists for a reason, and that reason is to let yous know that in that location'south something incorrect with your motorcar that may be potentially serious. That something could be a busted cylinder caput gasket, which, if ignored, will result in severe and highly expensive problems with your engine. Still think that piffling alert lite on the dashboard is insignificant?

Misfiring engine

Yous may ignore the warning lights on your dashboard, only y'all're probably a little less likely to ignore when your engine doesn't feel quite correct. If your auto'due south cylinder caput gasket is busted, then information technology may not exist creating enough compression in the combustion chamber. The outcome will be an engine that isn't quite performance properly, which will consequence in misfiring. Non familiar with misfiring? Y'all'll likely hear some popping noises now and then, and y'all may notice a loss of power.

Low coolant level

Your car's cylinder head gasket is a seal. When that seal isn't...well, sealing, then coolant can enter the cylinders. Do I really need to explain to you why coolant running away from home is bad? Coolant in the combustion sleeping accommodation ways coolant isn't where it should be, and that volition lower the fluid level in the coolant reservoir. Expect, you don't need to understand how your car works, or be able to perform repairs, or fifty-fifty alter a tire. But if you take some spare time on the weekend, maybe get in the practice of checking your car's fluid levels. That way you lot'll notice if y'all're depression on coolant, which could be a sign of a disrepair cylinder head gasket.

Coolant/oil intermix

If the head gasket fails, the oil and coolant passages inside the cylinder head may not be sealed off properly. As a result, coolant may enter the oil and visa versa.

Engine overheating

Some things can deal with overheating. When you accidentally put your popcorn in the microwave, sure, yous lost your popcorn, but no big deal. Not the case with your engine. An overheating engine is non a adept thing, and it's a sign that something isn't working right. If your car'southward cylinder head gasket isn't working, then the organization will be leaking coolant into the combustion chamber, and the coolant won't be able to practise its job, which is to keep the engine from overheating. You can probably gauge what happens next: an overheating engine. So, if that temperature estimate on the dashboard is rising, pay attending to it.

Heater doesn't work

The coolant in your machine has 1 primary purpose: To proceed the engine from overheating. But it has a notable secondary purpose as well: To heat the auto'southward cabin. Your car'due south interior heater gets heat from the coolant that circulates around the engine, absorbing oestrus. If the cylinder head gasket fails, the coolant will leak out of the system and into the combustion chamber, and in that location won't be enough coolant to warm the interior of the car. Which means yous'll probably be stuck shivering.

White smoke

You're not in college anymore. A fog machine might have made for a cool ambiance at your house parties, only you're long past that. Hopefully. White smoke emerging from the tailpipe of your car? Not a skillful matter. Not a expert matter at all. It's ofttimes caused past coolant leaking into the engine, which, if you've been paying any attending at all, is often the result of a damaged cylinder caput gasket.

Engine failure

If enough coolant leaks into the combustion sleeping accommodation, serious damage can occur to the engine. The coolant can also mix with the oil, keeping the engine from having acceptable lubrication, which will too pb to irreparable damage. If you pay attention to the to a higher place signs, y'all can get the cylinder head gasket replaced before your engine completely fails. But if you ignore them, you lot're in for a care for. And by "treat" I hateful "disaster."
