How To Fix A Intake Manifold Leak

If your car is suffering from a bad intake manifold leak, you may be feeling frustrated and powerless. Given how intricate these manifolds are, it’s not surprising that they occasionally go bad. In this post, we will guide you through the various steps you can take to fix this common issue. We will also provide tips on how to prevent manifold leaks in the first place.

Symptoms of a Intake Manifold Leak

If you are experiencing poor air flow or your check engine light is on, it may be time to take a look at your intake manifold. A Intake Manifold Leak can cause a variety of symptoms, including reduced fuel economy, engine stall, and rough idle. If left untreated, a Intake Manifold Leak can eventually lead to expensive repairs. Here are five signs that you need to address the issue:

1. Poor Air Flow – One of the most common symptoms of a Intake Manifold Leak is reduced air flow. This can cause your car to struggle to reach its performance potential, as well as experience decreased fuel economy.

2. Engine Stall – An even bigger issue with a Intake Manifold Leak is that it can cause your car to stall. This can happen when the system becomes overwhelmed and can no longer keep up with demand. It could also be the result of dirty air filters, which will reduce the amount of airflow through the system.

3. Rough Idle – Finally, if you notice an unusually rough idle or poor gas mileage, there’s a good chance that your Intake Manifold Leak is causing it. This problem stems from restricted airflow and low fuel economy because of blockages in the system.

4. Excessive Emissions – Another sign that you may have a Problem with your Intake Manifold is if you’re noticing increased emissions levels – either from CO 2 or other pollutants in the air.

Repairing a Intake Manifold Leak

If you have a car with an intake manifold leak, there are a few things you can do to try and fix it. First, make sure that the intake manifold is properly installed on the engine. If it’s not, the manifold may be loose and can cause the leak.

Next, check for any hoses or clamps that may be leaking. These might need to be replaced if they’re torn or cracked. Finally, inspect the overall condition of the intake manifold plumbing and bolts. If they’re corroded or bent, they may be causing the leak.

Adding Fuel to the Fire: Preventative Measures for Intake Manifold Leaks

Preventative measures to reduce intake manifold leaks include tightening engine bolts, checking and replacing gaskets, and flushing the system. Tighter engine bolts help to prevent loosening over time. Checking and replacing gaskets can help to avoid leakage at the joint where the intake manifold meets the cylinder head. Flushing the system helps remove any built-up debris that may be contributing to a leak.


If you’ve been noticing your car’s intake manifold leaking, there are a few things you can do to fix the issue. Start by looking for any obvious signs of damage, such as cracks or tears in the manifold itself. If you don’t see any visible damage, then your next step is to inspect the seals around the intake manifold. Many times, these seals are simply worn out and need to be replaced in order to keep water and other contaminants from seeping into the engine. If neither of those solutions work, then it might be time to replace the entire intake manifold.
