What Happens When the Intake Manifold Leaks?

Intake manifold leaks often result in a lean air-fuel mixture. Here is some relevant knowledge about the intake manifold: Symptoms of a faulty intake manifold: If the intake manifold is damaged, it will cause air leaks, leading to reduced gas pressure. This results in weakened intake capacity, decreased engine power, insufficient air intake, and increased carbon buildup. These issues are generally caused by cracks in the intake manifold, which lead to air leaks. Symptoms of an intake manifold leak: An intake manifold leak will produce noise, and the car may experience shaking, unstable idling, weak acceleration, and a tendency to stall. Severe cracking can even prevent the car from starting.
Last time my car had an intake manifold leak, the experience was really awful. At idle, the steering wheel shook like a phone on vibrate mode, and the tachometer needle danced wildly. When accelerating, there was no power even with the pedal to the floor, overtaking was particularly difficult, and fuel consumption kept rising. The engine warning light also came on inexplicably, and cold starts required several attempts before the engine would fire up. The most annoying part was hearing a hissing leak sound on the highway, like a tire slowly losing air. The mechanic said the leak could allow unfiltered air carrying dust into the engine, which over time could wear out the cylinder walls. If you notice these symptoms, get it checked immediately. Replacing a gasket only costs a few hundred bucks—much cheaper than an engine overhaul.
