Is daily driven and not used for any driving outside of the day to day routine. Contacted the dealership and while they see these gasket failures often they were unable to do any type of work on the vehicle due to it being outside of the warranty. This failure occurred while my wife was driving and instantly threw the car into limp mode, because of the lowered oil pressure reading, which resulted in a car unable to continue highway speeds and without knowledge of what limp mode was and what was occurring this could be a very dangerous situation that appears to be a common failure in the vq37vhr engine.

I was surprised this isn't already a recall issue. See all problems of the Infiniti G Car Problems. Engine And Engine Cooling problems. Car Stall problems. Engine Shut Off Without Warning problems.

We still have issues. The fasteners back off and cause leaks, etc. You will get a VTC timing chain rattle if it is really bad on a hot startup. Originally Posted by Spooler. Originally Posted by zer I know someone offers a kit with the metal gasket and new fasteners but I didn't see torque specs.

However, it feels like the transmission might fall out of the car when shifting. Most of the time, when you cut the car off and restart it, it runs as normal. It's like the computer resets. As of late, I have to cut the car off and restart twice. This is beginning to happen more frequently, like once or twice a week.

We have consulted with a dealer, and have tried several recommendations. We have new air filters and mas air sensors. This did not correct the problem. After further investigation, we found a dealership who admitted that they have seen or heard of this problem. The service advisor said that this could be a transmission issue. We have an appointment on with this dealership. See all problems of the Infiniti G My car was cutting off and over heating but it eventually locked up on me when I was driving on the highway.

Infiniti needs to recall the timing chain galley gaskets. My G37xs sedan recently blew the galley gaskets and it seems as if this is a common problem and is a very expensive fix. Recall this issue please I always use 93 gas. Always use mobil 1 full synthetic oil, and always do all maintenance on the car on time. I'm shocked and aggravated that this issue happened and Infiniti did not recall it.

The vehicle was in motion and would not enter 3rd or 4th gear. The car only has 55, miles on it.Five of the most prominent symptoms that your car has an intake manifold gasket leak. See how to spot a symptom, narrow down the cause and treat it. Let me explain: Your car's engine needs oxygen to create explosions within its cylinders to drive the car.

It is the role of the intake manifold to provide this oxygen. Coolant is also distributed to the cylinders in this way.

5 Leaky Intake Manifold Gasket Symptoms You Need To Know!

The intake manifold gasket is made of rubber or plastic and attaches the intake manifold to the engine. Due to strain from heat and the resulting contraction and expansion the gasket can get cracked.

Coolant and air can leak through these cracks, heating up and suffocating your engine! Not only does this lead to less performance, but your engine will suffer damage in the long term. Read this article for some more signs that your car is overheating. When there is too much air in the cylinders, not enough gas is let in. This leads to weaker explosions, which affects the speed of the pistons and the power of your engine.

True, all these symptoms can have many different causes. Keep reading to find out how you can detect a leak and confirm whether it is the cause.

Because of the number of misfires and the decreasing power of the engine, it will need to use more and more fuel to keep going. You will most likely also accelerate harder and harder to try and drive as fast as you usually do. In the beginning, the difference in petrol usage might be too small for you to notice, but as the crack gets worse and your engine performs less and less it will become more apparent.

If you drive roughly the same distance every week you might see your tank draining faster than usual. You will need to look for an air leak to know it is your intake manifold gasket. The easiest way to know that your car is leaking coolant is to check for an oily puddle underneath the front of your car. But how do I know if it is coolant or something else? Now that we have established that it is coolant that is leaking, we need to find out where it came from.

The intake manifold sits right on top of your engine. It should look kind of like a bridge with multiple metal tubes on each side. If the coolant leak is coming out where the manifold and the engine meet it is most likely caused by a damaged gasket. In this video, you can see the man look for the coolant leak at all the usual places and finally find that it is his intake manifold gasket that's the source:.

While coolant leaks lead to the engine overheating, air leaks lead to reduced performance. As you can imagine finding the air leak is not as simple as looking for an oil spill. Lucky for you, we are going to show you a few tricks to find an air leak!When your vehicle stops running all of the sudden, it is commonly due to a broken timing belt or timing chain.

Different engine combinations utilize either a belt or chain that is connected to the cam and crankshaft and is responsible for the internal operation of a combustion engine. They are both protected from exposure by a timing cover which can be opened and accessed by a mechanic to repair damage to these components or make adjustments as needed.

The timing chain cover is responsible for keeping dirt and debris from entering the inside of the engine. Due to the fact that the timing chain and belt are housed inside the engine, the timing cover even helps to keep the timing belt or timing chain solid and secure for smooth operation. The timing cover is constructed of plastic or metal and works in conjunction with the timing cover gasket to keep oil from leaking onto the ground.

Although the timing cover is not a moving part, from time to time damage may be done to the cover or the gasket inside that will require service or replacement by an ASE certified mechanic. When the parts wear out, they tend to display certain warning signs or symptoms. Noted below are a few of the common warning indicators that a problem with the timing cover exists. The timing cover has a gasket that allows the cover to be securely attached to the engine block.

Over time and due to exposure to heat, dirt, road grime, and more, the gasket can often become cracked or wear out. This will reduce the tightness of the timing cover and may result in oil escaping the engine and leaking onto the ground. A broken gasket is not the only reason why oil might be leaking from the timing cover.

In some cases the timing cover may be cracked, especially if it is manufactured out of plastic.

If you notice that oil is leaking from the center of the motor, near the front, it may be due to a faulty timing cover or timing cover gasket.

Another common signal that a problem with the timing cover exists is if the motor runs rough. When a timing cover becomes damaged and does not properly seal with the engine block, dirt and debris can enter the engine; especially in critical areas like the crankshaft or camshaft.

When this happens, the engine may run rough. If the problem is not fixed soon, it may result in complete engine failure. If you notice that the engine is running rough or sounds like it is misfiringplease contact a mechanic as soon as possible to determine the cause of this symptom and if needed, replace the timing cover.

When the timing cover is loose, it may cause a knocking sound to appear from near the front of the motor. If you hear this type of sound, drive the vehicle home as soon as possible.

Once you arrive home, open the hood and look right behind the radiator fan. If you see a flat, metal plate that appears to be shaking, this is most likely the timing cover that is loose. The sound is due to clanking against the engine block.

If this is happening, do not start the engine again. Contact a local ASE certified mechanic so they can inspect the problem and replace the timing cover if needed. The timing cover is designed to seal the engine and keep oil or pressure from escaping. If a pressure or vacuum situation occurs, sensors in the motor will trigger the Check Engine Light to illuminate on the dashboard.As with so many other seals in an engine, time and heat are the biggest enemies to a timing cover gasket.

Given that the timing cover gasket sits over an open window into your engine, one of the most common signs of failure is oil leaking from the timing cover onto the ground or down the front of the engine.

DIY: z Oil Galley. NOTE i was able to replace both galley gasket without having to take the timing chain off, its up to you on how comfortable you are with with resetting timing correctly. Remove all grounding connections off the top of the front timing cover and cam covers. Next remove the lower oil pan so you can reach two 10mm bolts that hold the upper oil pan to the front timing cover.

Take your time, the cover is cast aluminum and is easy to crack. One way is crank the motor till the primary and secondary timing marks line up. On bank 1, line up the two dots on the sprocket with the two orange links. You could also find TDC on cylinder 1 and make your own timing marks.

Using a philips head screw driver loosen each galley fasteners. NOTE use the correct philips screw driver, these fasteners are very easy to strip out. For the upper galley follow the same procedure, but in order to remove the fasteners behind the cam phaser sprocket you have to use a very small screw driver, or remove the secondary chain completely. Using a 4mm hex torque new fasteners down to 12 ft-lbs with lock tight. If you completely removed the timing chain, line up the the timing marks you made with the marker on both cam and crank sprockets.

Double check that cylinder 1 is at TDC and the crank marks still line up. With everything is in place pull the pin locking the tensioner in place. Once your positive timing is correct, you are ready to reinstall the timing cover. Intall coolant hard pipe and dipstick. JARbluejae35Knio and 15 others like this.
