Common Problems Encountered with a Porsche Cayenne Intake Manifold Gasket
Engines are complicated machines. They need to be running at a hundred percent capacity in order for them to runsmoothly. To do this, all cylinders and all pistons need to be firing at top condition. And what makes these pistons 'fire'? That's the combustion of air and fuel inside the engine, thanks to the intake manifold. The intake manifold gasket, in turn, makes sure that no wayward firing of fuel and air happens outside of the engine. A misfire outside the engine could seriously damage it, causing harm to your car in turn. Right here are some of the things you need to look out for if you want to avoid a bad manifold gasket.
The intake manifold gasket works in an environment where the temperatures aren't kept at a constant level. These gaskets suffer from high temperatures and an increased pressure. That's why they succumb to damage and develop leaks. A leaky intake manifold gasket may lower your fuel economy, raise your emissions and contribute to poor engine performance. This may also translate to your engine stopping to run altogether.
When coming to a stop, your car may experience some really bad shakes or shuddering. This can be attributed to the fact that one or more of your intake gaskets may be on the way out. Since they cannot function normally anymore, bad intake gaskets allow too much fuel or air into the cylinders. Usually, when one of your intake gaskets goes bad, your engine suddenly feels a bit more shuddery or shaky than normal.
You can also know a bad intake gasket by the sound it makes. This particular sound can be attributed to a leak or crack in the gasket. Since the intake gasket stops air from escaping or getting into the cylinder, when a leak is present, it makes a small whistling sound. You can also gauge the damage from the sound the gasket makes. A bigger leak or crack will usually produce a more defined sucking sound than a whistle. Aside from the sound, it can also come along with leaking fluids and a rough idle.
There are leaks which couldn't be seen easily. Internal leaks are one of the trickier situations an intake gasket may go through. In an internal leak, the coolant manages to seep to the inside of the engine, to mix with motor oil. Checking your oil dipstick reveals if you have an internal leak problem. If there is rusty residue along with the milkshake-like consistency of your oil, you might have a leak.
