Experienced mechanics share their insights in answering this question :
Hello. If the engine mounts are bad then they need to be replaced. Many times the vehicle will only need one mount if the issue was found early enough. If it was put off for a long time then that will put extra stress on the other mounts which can cause them to fail prematurely. I usually check each of the mounts to see which ones are bad and which ones are fine. If any are questionable then I replace them also because a worn mount will cause a brand new mount to fail quickly. If you want to have your car checked out, consider YourMechanic, as a certified mechanic can come to your to inspect the issue and replace the engine mounts if necessary.

While you don`t necessarily need to change all engine mounts at once, if you don`t replace them all, you should pay closer attention to them, as they`re likely to be the same age as the part you`re replacing.
You`ll need to lift and restrain the engine somehow to replace the old mount.
Generally, motor mounts last a very long time, sometimes the lifetime of the vehicle. However, depending on operating conditions, they can wear out as the miles add up. To avoid excessive damage or serious safety problems, it`s a good idea to have the motor mounts inspected to make sure they don`t need to be replaced.
Having drastically differently loaded engine mounts can cause an imbalance, resulting in poor isolation and premature failures. In fact, unevenly loaded mounts can cause more vibration rather than less, defeating the purpose of the engine mounts.
Typically, one motor mount fails before the others. As an engine revs, it wants to rotate in the same direction as the crankshaft. That tends to stretch one motor mount and compress the others. Usually, the mount that stretches is the one that fails first, Mazor said.
If you are having a motor mount issue, it is very important to get it looked at by a professional mechanic and repaired as soon as possible. A failing motor mount can lead to serious engine damage and will also greatly impact the performance of the vehicle. It is very unsafe to drive with a broken motor mount.
Problematic motor mounts will typically show signs that will let you know that there is an issue and that should be serviced. The first obvious sign of bad motor mounts is; excessive engine vibration.
Factory original mounts last a pretty long time, but engine oil leaks are a common cause of premature degrading. Worn mounts will allow a running engine to shift and bounce in all kinds of unpredictable, power-sapping ways.
Motor mount replacement is a big job, though, so be wary of any mechanic or dealer that is offering to do the job for a price that seems too good to be true.
Motor mounts keep your engine attached to the car. Weak or broken mounts can`t hold the engine tight in the engine compartment and creates a vibration at idle.
Poor quality or worn engine mounts may cause excessive vibration and misalignment. Damaged or worn engine mounts should be replaced as soon as possible to avoid misalignments resulting in machinery failure.
If quality parts are used, mounts should last much longer than 2 years. Mounts are basically rubber between a couple of metal plates (this is very simplified). In OEM mounts, the rubber just ages and wears out. Now also oil leaking onto the rubber will cause it to deteriorate very rapidly.
Over time and use, hydraulic engine mounts can start to fail and “pancake.” This can directly affect the height and position of the engine, which not only leads to a deteriorating ride, but also has the potential to damage other components such as the cooling fan and shroud.
Bad engine mounts can also lead to damaged fan belts and/or radiator hoses. While this typically occurs at high speeds, it`s important to check your belts and hoses for any damage.
Car`s `clunking` and `jerking` are classic signs of bad motor mount.
If you fail to replace your engine mounts when they are breaking, your entire car might suffer damage. With the heavy engine shifting under the hood, it can knock into other vehicle components. Naturally, this also causes unreasonable wear and tear on the engine and transmission.
One of the first signs that your engine mount is going bad is abnormal vibrations. The mount absorbs most of the vibrations caused by the combustion cycle, so without them working properly, you may feel some jittering or shaking while driving – especially when you`re idling or braking.
No, they aren`t. Typically there are four main mounts that support the motor and the transmission.
Tighten the engine mount to body nuts to 66 N.m (49 lb ft).
For a motor mount that is right on top of the engine it may only take 30 minutes for a mechanic to swap out the old mount and replace it with a new one.
Heavy Vibrations: One symptom of a bad motor mount could be heavy vibrations. This might make you feel like your car is “bouncing” down the road. Clunking and Shaking: Another symptom of a bad motor mount could be clunking or shaking when driving over bumps in the road.
Simply put, stiff engine mounts make the engine more present in the cabin. Engine mounts are an interesting mod that can end up making a car worse, so keeping it stock isn`t the worst thing. But it is one of the many small parts of a car that can be tuned to offer a different experience rather than more performance.
Performance motor mounts are made out of stiffer materials to absorb less power and instead put that power directly into the ground. These alternative polyethylene or metal brackets offer greater upgraded specifications over factory-installed rubber.

p0011 code,check engine light one, changed bank 1 vvt solenoid and check engine light still on?
ANSWER : The P0011 code is typically caused by oil issues with the car. I would particularly make sure the engine oil level is not low. The VVT solenoid relies on proper oil levels to do their job. If they don’t have enough oil, they won’t work. You can have a mobile technician from YourMechanic visit your home or office to inspect the Check Engine Light for you. If you follow through with a repair with us you will be reimbursed for the cost of inspection.

Car vibrate when in "D" or "R" although I have changed the 4 engine mounts. Changed 4 sparks and air filter and throttle cleanse
ANSWER : It seems you have covered the basics and changed the most common culprits for engine vibrations. I will recommend you have an experienced technician inspect the work done and the drivetrain for other problems. In some cases, an improperly installed new engine mount can cause a vibration to stay. Hire one of our experts here at Your Mechanic to inspect the previous work done and diagnose the source of the vibrations.

Replacement time interval for changing engine mounts or automatic transmission mounts for 2009 Nissan Versa Hatchback
ANSWER : Hello – there is no prescribed maintenance interval for engine/transmission mounts for most any passenger vehicle. The length of time engine/transmission mounts will hold up is directly related to how briskly you accelerate, how smoothly your engine runs, and so on. Hydraulic mounts are more likely to fail with shock loads like violent acceleration at a stop light, "torquing" the engine at a light (holding the gas pedal down while in gear, and holding the brakes on at the same time). These are factors in determining the life of an engine or transmission mount. I recommend an engine/transmission mount inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.

Check engine light refuses to go off after engine replaced
ANSWER : Hello there, you have a long series of issues going on with your 2013 Hyundai Sonata. If you keep getting a repeating oil light on than there is likely a fault in that system.

Since this fault has lasted after the engine was replaced it could be a oil pressure sensor, wiring harness fault, ECU fault, oil pump, oil strainer clogged, or low oil pressure.

To diagnose this issue properly you need a complete vehicle inspection to start from square one and identify the root cause of all this.

How do you replace the rear & side engine mounts without lifting out the engine? & how do you lift the engine out?
ANSWER : Hi…thank you for your questions. If required in the application, a portable engine support bar is used to support an engine during mount replacement. The support bar has lifting capability as well so that the mount can be unloaded and removed. If a particular repair application requires a "crane" (complete engine removal for instance), such are portable these days in any event. With regard to the exhaust system repair, mechanics use ramps to gain access. Six ton portable jack stands will safely support a car two feet into the air which provides more than enough access to repair or replace any exhaust system component. If you desire replacement of the mounts, please refer to YourMechanic’s motor mount replacement service page. For exhaust leaks, please use the exhaust system inspection/repair page page. Once on each of those service pages, if you click on "Get a Quote" and enter your vehicle information (year, make, model) you can obtain cost info and schedule the service. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

The engine klunking and tapping, needs engine replacemet
ANSWER : The reason the shops told you to replace the engine is that they do not overhaul engines. They can only replace it for you with a remanufactured or used engine. An overhaul is a third option but would most likely not be as cost effective and may even cost you more since the labor and parts can be more than replacing it. Since you already had two shops say it needs an engine, then I would suggest having them both give you quotes on remanufactured or used one. Make sure to get the warranty in writing so you can see if a future failure is covered.

How do I turn off the check engine light after changing the timing chain?
ANSWER : Hi, thanks for writing in. I’d be happy to help. Once the check engine light is on, the computer memory will need to be cleared. This has to be done with a computer scanner hooked to the OBD-II connector. If you have a computer scanner, you won’t need to go to the mechanic.
