I decided to remove my intake manifold to clean it and remove the rear motor

I DECIDED TO REMOVE MY INTAKE MANIFOLD TO CLEAN IT AND I REMOVE THE REAR DRIVE MOTOR AND BY MISTAKE I move funnel how to set the funnel the right way I hear top funnel only open up at 3500 rpm and the lower at 6200 rpm so this means is not support to open on less you are driven above 3500 rpm so it hold the vacuum compression.

My car has 85000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hello. The variable intake should reset once you put everything back together and run the engine. If the intake flaps are stuck, then there may be debris stuck in them from carbon build up, or the motors may have been damaged when you had it apart. I would clean them and re-install it and drive it. I usually use a scan tool also to reset the adaptive memory which can help. If the problem persists, then it may need a new actuator motor. If you need to have this looked at, consider YourMechanic, as a certified mechanic can come to your home or office to inspect the system and make the correct adjustments.

Over time, important parts within your intake manifold can become coated in soot, which can negatively affect the performance of your vehicle. It is important to clean your intake manifold properly, as the air it provides your engine is key to performance, economy, and efficiency.
Follow the easy steps below to remove the intake manifold and have your car purring again. Remove the air filter and air filter container. Pay close attention during the removal process; you will have to reconnect all the parts when replacing the intake manifold. Open the hose clamp with a flathead screwdriver.
The latest “improved” manifolds can often generate an additional 20, 30 or even 50 or more horsepower on many of these larger displacement engines compared to what was possible using an older manifold design. Runner length also affects the rpm range where an engine makes the most power.
We recommend it every 60,000 miles or whenever you notice performance issues. A complete fuel system cleaning is not recommended as a preventative service; it is only necessary when you are experiencing problems. Signs that your vehicle needs a fuel induction service include: Emissions inspection failure.
But the truth is, intake manifold cleaning is an important part of diesel maintenance. Not only does it help keep your diesel engine running smoothly, but it can also improve performance and fuel economy.
Engine misfires and violent vibrations can be caused by an air filter that is dirty and clogged. The clogged air filter may allow oil to burn improperly, thus contaminating the spark plugs of your engine with excess oil deposits.
If the intake manifold is bad, it can mess with the engine`s air-fuel mixture, which can then mess with the engine`s performance. You may see a reduction in power, uneven acceleration, and even backfiring. The same is true for the engine`s cooling system.
Non turbo diesel engine will run fine, they run wide open intake only and are controlled by the amount of fuel injected.
In addition to a possibly rough, uneven idle speed, you may also hear whistling, sucking, gulping or hissing noises. Your check engine light comes on: Abnormal operating conditions and loss of performance can result from a bad intake manifold.
A larger combustion = more power. Cold Air Intakes are said to improve your vehicle`s performance by 5-20 horsepower. This number will vary depending on the make and model of your vehicle. While this isn`t enough power to put you back in your seat, it will give your car or truck a little pep in its step.
It makes such a big difference, in fact, that the simple process of redirecting the filter to draw cooler air is good for a horsepower gain of about 5 to 20 ponies in most cars. It might even improve your fuel efficiency, and it`ll probably make your engine sound better, too.
Petrol / Diesel engine intake and carbon cleaning is an essential but often overlooked part of maintaining a modern diesel engine. Ideally you should look at having this service performed every 60,000kms for Diesel Vehicles and 100,000kms for Petrol Vehicles.
This service not only cleans the fuel injectors, throttle body, intake manifold clear through the exhaust system, it can also decarbon the combustion chamber, the top of pistons and the intake and exhaust valves.
The stock intake manifolds on most model mustangs are designed to be more functional than powerful. They are designed to get consistent results, and to be cost effective for production. Upgrading your intake will not only increase horsepower, it can also change the rpm range at which the most horsepower is created.
You will not get intake flaps clean on a direct injection engine with an HHO carbon clean. That will require the manifold to be removed and cleaned using walnut shells or similar.
A clogged or failed exhaust gas recirculation or crankcase ventilation valve or faulty oxygen sensor can send the wrong signals to the computer and cause misfires.
The type “A” misfire is the most serious condition and indicates impending catalyst damage. If detected, the Malfunction Indicator Lamp (MIL) may flash once per second to alert the driver that immediate service is required.
The idle speed should feel consistent without skipping or slipping. In most of today`s cars, an idle speed of 600 to 1000 RPMs is average. If your car is idling rough, though, it won`t feel smooth. The RPMs will jump up and down, for example, or they`ll fall below 600 RPM (or whatever is typical for your vehicle).
If too much air is added to the air and fuel mixture, then your engine will be rough idling. A dirty fuel injector can also cause rough idling. The fuel injector administers the correct amount of fuel into the engine`s cylinder at the appropriate time for a smooth function.
The compressor relies heavily on the manifold hoses that are attached to it to circulate the gas correctly and efficiently. These hoses can sometimes fail by simply developing a small leak that, over time, will cause the refrigerant levels to become low.
As is the case with most things engine related, bigger is not always better and plenum size can affect torque and horsepower. Generally speaking, smaller plenums allow for quicker, low-end torque production at the expense of high-RPM, top-end horsepower.
In automotive engineering, an inlet manifold or intake manifold (in American English) is the part of an engine that supplies the fuel/air mixture to the cylinders.
Air intake systems are vital parts of your car`s engine. Without air intake systems, your engine might not run at all, and it certainly wouldn`t be controllable to the same degree.
The intake manifold also helps cool down the cylinders to prevent the engine from overheating. Coolant runs through the manifold to the cylinder heads where the coolant absorbs the heat and reduces engine temperature.

Oil is geting into intake manifold and into all intake vavles.
ANSWER : Hi there. That type of oil volume inside the intake manifold is typically a sure fire indication of a blown head gasket. It’s also quite possible that this has occurred for an extended period of time. There are a few things that you can do to verify that this is the head gasket. First, check the oil itself. If it is milky or foamy then it means the head gasket is damaged and coolant is leaking into the oil galleys. If the head gasket is not damaged, excessive oil inside the spark plug well could also be a damaged O-ring but can also be the result of a failing piston or worn valve guides. Either way, the only way to correctly inspect and diagnose this would be to tear down the motor, so you might want to consider whether you are wanting to complete repairs or purchase a newer vehicle.

Loud metallic clunk and stops cranking when trying to start after removing and reinstalling upper intake manifold,
ANSWER : Hi there. Check the fuel injectors and make sure that they are hooked up properly. A leaking fuel injector will cause fuel to flood the cylinder and hydro lock the piston making the engine stop cranking. Also, check for anything that could be missing. It is possible that during the removal and installation process of the intake may have had a nut or bolt go into a runner on the cylinder heads. When the intake valve opens, the object will enter the engine causing the engine to have a clunk sound as well. I recommend seeking out a professional, such as one from Your Mechanic, to help you if you are unable to locate the clunking source on your engine.

I have coolant in my lower intake manifold after replacing the gasket in my upper manifold in my 1996 Chevrolet Suburban.
ANSWER : 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 completely clean. If you do not then you can cause some serious internal engine damage.

if i wanted to remove the intake manifold because i have a vacuum leak; would i have to remove the fuel rail
ANSWER : You should first confirm the vacuum leak by carefully introducing propane (or equivalent) at the suspected leak site. If introducing propane at the leak site increases engine speed, then you have a vacuum leak. Perform the test outdoors and be careful about other ignition sources.

The fuel rail of course has to be disconnected from the supply and return lines. During an operation like that you are performing, the best practice is to remove all injectors from the fuel rail and mail them to a lab such as Mr. Injector. They will replace the miniature internal filter in each injector, clean the injectors ultrasonically and test them and supply you with a report. Regarding your question, you ONLY have to remove the fuel rail if the rail blocks access to the intake manifold bolts. If the bolts are accessible with the rail in place, and in particular accessible to a calibrated torque wrench on re-installation, then you do not have to remove the fuel rail. As noted though, strictly speaking it’s a moot issue, as the best way to do the job is have the injectors professionally cleaned while you have the intake off.

Exhaust leak coming from the rear manifold exhaust gasket and I was wondering how do you replace the rear manifold exhaust? 2006 Chrysler Town & Country
ANSWER : Hello – most likely, this is an exhaust leak between the exhaust manifold, and the cross-over pipe. Removing the cross-over pipe will be the required process to replace the leaking gasket if this is the source. i recommend a engine noise inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, confirm this diagnosis, and give you an accurate assessment of damage and cost estimate for repairs.

Roland, does the 2007 4.7 liter with the plastic intake manifold have coolant passing through to cool the manifold?
ANSWER : Hello. It does not appear that the intake manifold on that model has coolant passages, so it is unlikely that that is the cause of the issue.

I would still carefully examine the intake manifold for any signs of warping, however, as plastic manifolds are more susceptible to warping than aluminum ones.

If the compression test was performed on a cold engine, it may be possible that a cold engine helped seal the pressure. If it feels safe to do so, I would start the engine, warm it up to operating temperature, and then retest the cylinder compression. There are certain cases where the head gasket is blown or the cylinder heads are warped, however, only once the engine is warmed up and the metal expands. If you’d like a second opinion on the car, a certified expert from YourMechanic can come to your car’s location to inspect the overheating problem and diagnose the issue properly.

Code p0010 camshaft actuator comes up, and mis fires. Just replaced intake manifold and these weren’t issues before that.
ANSWER : Hi there. There are a few possibilities here. It is possible that you had a valve timing issue prior to working on the manifold. These engines have a ton of issues with the balance shaft and the valve timing as the chain wear. It is also possible that there are issues with the work that you did. I have seen with these manifolds, severe warping and cracking which will cause this to occur. I would start by checking the manifold for vacuum leaks. If there are none then next the wiring needs to be checked for any pinched wires. If that is all fine then I would install a scan tool to check the camshaft and crankshaft sensor readings. If they are off then the valve timing needs to be checked.
