Mercedes Benz CLK430 Intake Manifold Gasket
How to Know If There's Bad News for Your Mercedes Benz CLK430 Intake Manifold Gasket
Also referred to as IMG, the intake manifold gasket is made of rubber and is secured beneath the intake manifold to provide a tight seal. It needs to do so because the intake manifold is responsible for supplying a mixture of fuel and air to the combustion chamber. Anything that gets in the mix will cause a lot of havoc. The intake manifold gasket keeps that fuel from leaking from the intake manifold and prevents additional air from being sucked into the engine. All vehicles, like the Mercedes Benz CLK430, are prone to intake manifold gasket problems. These are just some of the frequent signs of those problems.
The most well-known symptom of a bad intake manifold gasket is leaking. An intake manifold gasket with leaks has openings on it that will allow water, coolant, or a mixture of both to leak from the engine. This will result in a messy puddle of water and coolant on the ground. This is certainly bad news for your car because frequent loss of water and coolant will make the vehicle overheat, risking other car parts as well.
A normal and healthy engine has an optimum fuel to air ratio that is specific to every model. If an intake manifold gasket fails, it can disrupt this balance and allow too much fuel or air to reach the combustion chamber. Because of this, the levels of fuel and air in the engine will continue to fluctuate as the car eventually idles and dies. An engine that is idling roughly will cause the vehicle to shake, vibrate, and shudder. However, this will be lessened if the vehicle is on the move.
Since the intake manifold is an avenue for fuel and air, any crack or looseness will draw air into the engine through that small breach. This resonates through a whistling sound. However, if the crack or leak is large, a sucking noise comparable to a vacuum will be heard as the engine pulls in more air. Any noise will be accompanied by leaks or idling.
