Crack on engine cradle

My daughter hit a guardrail on the driver's side. After taking off the tire, I noticed a crack on the engine cradle. Is this repairable?
Experienced mechanics share their insights in answering this question :
Depending what part of the vehicle has cracked, it may or may not be repairable. If the crack has occurred on a replaceable component, such as a bracket, mount, or perhaps suspension arm, then it may be replaceable. However, if the crack has occurred directly on the vehicle’s subframe, or frame, then this may be a more difficult repair to attempt. I would recommend having a professional technician, such as one from YourMechanic, look at the cracked component, to see if it is indeed repairable or replaceable.

How to Identify and Fix Common car Problems ?

An engine cradle or “subframe” is an essential structural component of a unibody vehicle, the most common type of passenger vehicle structure on the road today. The cradle supports the engine, transmission, and front suspension.
An engine cradle is typically manufactured from welded steel stampings and is bolted to the vehicle body.
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. If you feel a lot of vibration in the vehicle while you are driving, there`s a good chance it`s the motor mount.
Installing a new engine cradle, replacing the axle and the transmission mount costs $1,600.
In the majority of cases, subframe damage is a result of a high-speed (i.e. 30+ mph) collision. Keep in mind that this doesn`t necessarily mean a collision with another vehicle. Hitting a curb or a pothole can also cause the subframe to crack or bend. Another common reason for subframe damage is bushings decay.
An engine mount is exactly what it sounds like – the part of your car that holds the engine in place. Because your transmission and engine are bolted together, you need mounts to keep them from moving around. Usually, there`s one mount holding the transmission and two or three holding the engine.
If an engine mount breaks off from an engine, there will no longer be effective support. Damaged components can create a safety hazard for yourself and other motorists if other components break or fly off due to engine mount wear. Engine movement or misalignment may occur as a result of engine mount failure.
A cradle or a subframe is a chassis structural component that is utilized to support the engine/powertrain in front wheel drive vehicles.
Frequently, rebuilt engines are superior to even new car engines because better parts are used, or design changes in parts correct problems with the original engine. Rebuilt engines are dependable, reliable and are backed by the engine manufacturers warranty program.
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.
Worn or dirty spark plugs can cause a petrol car`s engine to misfire in one or more cylinders, which can cause vibrations when the car is idling or at running speeds. The easiest solution is to replace your spark plugs and check the related wiring. Engine vibrations can also be due to the air and fuel systems.
A cracked subframe can indeed be welded. However, this is only advisable if you caught the issue early on. If the damage is minor, patching it up won`t compromise the integrity of the subframe in the long run.
If the frame or structure of your car is severely damaged, then it is not safe to drive such a car. This is because the overall integrity of your car frame has been compromised. As the purpose of the frame is to keep the vehicle stable, so if the frame itself is damaged, then it may be dangerous to you while driving.
In broad terms, the engine can be segregated into three key parts, the head, the block and the oil sump. 1. The cylinder head is the channel through which the fuel enters the engine chamber and exhaust gases exit.
Moving parts of an engine

The principal moving parts are the piston assembly, the connecting rods, the crankshaft assembly (including flywheel and vibration dampener),the camshaft, the valves, and the gear train.

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.
Motor mounts are made to hold your engine in place and absorb vibration. If your engine is shaking in place, it`s probably a sign of bad motor mounts. In extreme cases, the excessive vibration can be felt when sitting in the vehicle, particularly from the passenger side.
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.
The word cradle comes to us from the Old English word cradol, which meant “little bed or cot.” And while it is important to cradle a baby`s head when you pick them up out of their cradle, this word isn`t all baby talk.
A bassinet, bassinette, or cradle is a bed specifically for babies from birth to about four months.
With good workmanship, rebuilt engines can last just as long and work as well as the former engine that was originally installed in your classic car. Usually, you can expect a rebuilt engine to keep going for at least a few years.
An engine rebuild is known as a process where the finished product is considered brand new from the inside out. All the parts of the engine that display signs of wear are replaced with brand new replacements. The parts that could be replaced include the valves, pistons, bearings, and seals.
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.

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.

I have a 2010 camry. I just recently replaced the engine with a 2014 camry engine. Now I have Four engine lights on. I replaced on
ANSWER : If you swapped the engine from a vehicle that is 4 years newer than the car is then you are going to have electrical and sensor incompatibilities that may not be able to be fixed by just a few sensor replacements. There were many changes in computer and emission related items between 2010 and 2014 engines. I would recommend having a mechanic like one from YourMechanic come to you and compare the two engines to isolate the possible differences and see if the problem can be fixed.

Engine malfunction light, reduced engine power, engine powered down
ANSWER : Hi there. There are a lot of things that can cause this on your 2012 BMW M5. I usually start by scanning the computer for codes to see what comes up. If there are not codes then I load test the alternator and the battery to see if they are failing. Low voltage in the electrical system will cause this. If that is fine, then it is usually caused by a failing throttle body. I have seen a lot of these fail due to the motors in them hanging up. If the problem is only happening intermittently, this can make the issue hard to duplicate, but you can still have tests done on the car. If you are going to have this fixed, consider YourMechanic, as a certified mechanic can come to your home or office to test the vehicle and diagnose the Engine Malfunction Light.

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.

Check Engine light on. Would the computer give all error codes in one shot? How do we know the engine’s condition?
ANSWER : Hi there. From the description you have provided, I’m am inclined to agree with your assessment of a used engine being installed in your vehicle. An inspection of the engine, by a qualified technician could determine whether the engine is sound. The Check Engine Light on and having a TPS (throttle position sensor) code does not necessarily mean the sensor is at fault. Circuit tests should be performed to confirm the fault. The likelihood of the ECM (electronic control module/computer) giving you all the codes at once is remote. Other component failures could occur. Address those as they come up. Even though you already made the purchase, I recommend having your vehicle inspected by a certified technician so that you can get a thorough evaluation of the car’s true condition.
