Intake Manifold

This is a common issue on your vehicle. The intake manifold on your vehicle is made of plastic and mounts to an aluminum cylinder head. These materials expand and contract at different temperatures and this creates leaks. This problem is...

There can be many reasons for an engine to stall. Since the Check Engine Light is on I would start with scanning the computer for codes and moving forward with a diagnosis from there. You may have a vacuum leak...

You are correct. The most likely cause of an intake manifold leak, is gasket failure. These gaskets fail for a number of reasons and can be swapped out in a day. The majority of the process is removing the manifold...

I recommend having a certified technician, such as one from YourMechanic, come out to your car's location to run a diagnostic inspection of your oil leak (https://www.yourmechanic.com/services/oil-fluid-leak-inspection), and suggest the best path to repair.

Hello there. A decrease in fuel milage can be attributed to a few different faults. The most common causes are leaking fuel injectors (https://www.yourmechanic.com/services/fuel-injector-replacement), oxygen sensors (https://www.yourmechanic.com/services/oxygen-sensor-replacement), coolant temperature sensors (https://www.yourmechanic.com/services/coolant-temperature-switch-sensor-replacement), vacuum leaks or exhaust leaks. A qualified technician, such...

You should never disconnect the battery while running or it can spike the computer and alternator and damage them. The white smoke is coolant getting into engine from a leaking intake manifold or head gasket leaking. Check upper intake seals...

Hello, thank you for writing in. Simply pulling the mass airflow sensor is not a good enough test. You will want to test it with a multimeter to get an accurate reading on how it is working. The symptoms you...

A lot of these engines had plastic intake manifolds that crack and leak. First the system needs pressure tested to isolate the leak and then a replacement intake may need to be installed. To give a price without seeing and...

Hi there. If you have coolant in your lower manifold also then at the very minimum you need to blow it out with compressed air. I would recommend removing the lower manifold also to make sure that you get it...

There are reports of failure, and consequent leaks, of these plastic manifolds. Indeed, there was a settlement involving a range of Ford products years ago. However, looking at NHTSA (http://www.safercar.gov) data and other sources, I cannot find evidence of any...

Hi. This is a very common failure on vehicles like yours. So common, in fact, that there is a technical service bulletin (TSB) on it. The TSB is XT303-13 and it addressed the hissing sound from under the hood, as...

Intake and exhaust manifolds do not effect each other. If you had an exhaust manifold leak then you will hear noise but it should not effect the way the engine runs. If you have an intake manifold leaking then your...

Hello. If the stalling condition is reproducible, it will be easier to diagnose. The first thing to be done is to scan the vehicle for codes and data. There are many reasons for a stalling condition, like fuel pressure, vacuum...

The Check Engine light requires a special scan tool to determine the issue. Additional diagnostics may be required. An intake leak is common on this engine and may cause leaks, low fluids, and many other issues. With the vehicle sitting...

Many cars and trucks now have plastic intake manifolds and I believe your F150 is one of them. They crack, it's a simple fact of life. The plastic is pretty good, much better than the plastics of decades ago, but...

The intake manifold runner control does not come apart and is part of the intake manifold. you will need to replace it as an assembly. The parts and labor will have to be priced locally by contacting YourMechanic.

I'm guessing you have the common P2004 code, which stands for 'Intake Manifold Runner Stuck Open.' While the manifold runner valve is a common reason for this code, there are other potential culprits as well. A mechanical problem with the...

Hello. Typically intake manifolds do not wear out from use. Your vehicle should have a plastic manifold so unless the engine was overheated at any point it should not wear out. If the vehicle is not properly maintained then it...

You need to check the oil and coolant to see if the coolant is low and oil is contaminated with coolant. This engine is known to have intake manifold coolant leaks into the engine and the head gaskets leak coolant....

On your model, it probably takes around 4 hours to replace both the upper and lower intake manifold gaskets but if you have rear A/C it is somewhat longer. A gasket kit is necessary because other gasketed parts are removed...
