If you think an “exhaust manifold gasket failure” sounds like a pretty big problem to have with your car, you’re right: it is. It can be especially concerning when it occurs in a finely-tuned, precision-engineered vehicle like a Jaguar. But if your Jaguar is experiencing these problems, you can put your mind at ease with this handy guide to fixing your exhaust manifold gasket failure.
What is an Exhaust Manifold Gasket?
Perhaps the first and best step in solving this problem is to begin by understanding what your exhaust manifold gasket is and how it functions. For starters, it’s helpful to understand that this is actually a two-fold piece of your vehicle: the exhaust manifold and the exhaust manifold gasket. The exhaust manifolds are important because they are the metal components that work to collect exhaust gases and transport them to the exhaust to be sent out from the tailpipe. They are connected to the engine cylinder heads—and in fact, are bolted down— and they’re sealed by a gasket which is known as—you guessed it—the exhaust manifold gasket.
The exhaust manifold gasket is, in turn, a multi-layered gasket that is responsible for conducting the flow of exhaust. And because it is the first line of defense in the exhaust system, a problem with the exhaust manifold gasket can lead to additional—and severe—internal injuries for your vehicle. This is the number one reason why this piece of your vehicle should be inspected frequently and carefully by a trained mechanic who can diagnose any issues and inform you of next steps.
Symptoms of Exhaust Manifold Gasket Failure
However, if you’re interested in identifying these issues on your own, here’s what you need to know to diagnose exhaust manifold gasket failure. Fortunately, there will be a number of visual and audible clues that can help you detect the problem early on.
Excessively Noisy Engine
Unlike some mechanical failures, this is not a silent problem. If you’re aware of what to look for, you’ll be able to identify an exhaust manifold gasket failure right away due to the engine noise. Because the main component of this problem is an exhaust leak, you’re likely to hear a very loud hissing or tapping, sputtering sound coming from the engine. It’s likely to be especially noisy when your car is accelerating, so this is an automatic clue.
Decrease in power, acceleration, or fuel efficiency
As previously mentioned, exhaust manifold gasket failure can trigger a number of different issues in your Jaguar, and these are just a few of them. So, whether you’re hearing an excessively noisy engine or not, if you’re noticing a sudden decrease in power, acceleration, or fuel efficiency, you’ll want to keep an eye out for potential problems with your exhaust manifold.
A burning smell is definitely one of the most disconcerting warning signs to notice with your vehicle, and it’s even more disturbing if it’s coming from your engine bay. This will almost certainly be the case in the event of an exhaust manifold gasket failure because the exhaust leak will affect the engine. This can occur because of the exhaust leaking near any plastic components or—more worrying—the engine wiring. This can cause any one of these components to burn, and that will be the source of the smoldering smell that will reach you.
How You Can Fix It
As you’re no doubt aware, any signs of burning, power failure, or disturbing noises should be investigated as soon as possible. It’s also important that they be investigated only by a trained mechanic who specializes in German automotive engineering. Although it might be possible to fix an exhaust manifold gasket failure on your own, it is a highly involved—and potentially dangerous—prospect that is best left to mechanical professionals. And if you’re in the Winter Park or Orlando areas, the best mechanical professionals near you can be found at Green Garage European Auto Centre.
