When to Get Intake Manifold Repaired?
The intake manifold is the bunch of pipes joining the engine usually on the top. It is hard to miss but it is also often very hard to disassemble, therefore, it is better if you let the mechanic do this part. However, if you are proficient and qualified enough to open up the intake manifold, go for it! Once you have opened up the manifold, first take out the gasket and check if there is a crack somewhere on it. If there is, you are looking at a blown gasket and it is easily replaced. But it cannot be repaired, so you have to change it.
Also check for any signs of cracks in the intake manifold from which it could take air from. If your intake has swirl flaps inside, check the swirl flap inside the manifold and if they’re broken, you have to replace the whole manifold.
