Hear engine noise

ANSWER : The noise associated with steering at low speed is not related to the fault causing code P1717 to display. The steering related noise could involve the power steering pump and/or drive belt although there are other possibilities. To pinpoint the source of the noise you are hearing, the recommended service is a power steering system inspection.

With regard to code P1717, that code sets if there is a problem involving the transmission selector range switch. Among the possible faults is a faulty transmission range switch, the transmission range switch harness is open or shorted and/or the transmission range switch circuit has high resistance electrical connections. To resolve that issue, the appropriate service is a check engine light diagnostic – code P1717. During such a diagnostic, a certified mechanic from YourMechanic would retrieve all the diagnostic trouble code(s) from your car’s PCM that have caused the check engine light to illuminate. Using those codes, the appropriate individual vehicle components or sub-systems (often a sensor, circuit, and the like) are tested to pinpoint the cause of the fault or the reason why the check engine light has illuminated. Once the faulty part or component is identified, it is explained to your satisfaction and the mechanic will let you know of the cost to repair.

ANSWER : Hi there. It appears you have more than one problem with your vehicle. The noise coming from engine area with a load on the electrical system, may be a bad diode in the alternator. Continuing to drive the vehicle with a bad alternator diode, may leave you with a dead battery. The hot air coming from the vents sounds like blend door actuator(s) problems. I recommend the concerns your vehicle has, it be inspected by a certified technician like one from YourMechanic to pinpoint the noise and help you fix it accordingly.

ANSWER : Hello, thank you for writing in. There must be more diagnostic work and testing done to determine what the issue is. Without a drive or timing belt, the engine would either not run at all, or perform very poorly. This does not mean that an inspection of the timing belt/chain should not be done. There are other components in the timing belt system that can become damaged and cause issues. The valve and lifter consideration is valid, and can be inspected visually with some time and energy. Unfortunately you may also have crankshaft end play or a bad camshaft bearing. Use the location of the sound to help you determine what to check into first. One by one, check into the systems in that area until you find the culprit. For more help resolving the noise, contact our service department.

ANSWER : Hi there. A binding accessory could be causing your concern. Simply remove the drive belt and recheck. If the problem goes away, this eliminates the fear that there could be something goin on with the engine or transmission internally. It sounds like this could be the water pump. If the water pump is binding or leaking, it can cause the belt to slip and make it seem like the engine gets bogged down. Usually a visual inspection quickly uncovers the leak. However a properly executed pressure test is the best way to uncover leaks, both current and potential. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a car is making a noise inspection.

ANSWER : There should be no appreciable run-out on the crank pulley and if a physical inspection of the harmonic balancer reveals damage such as a broken, cracked or separated rubber bond, the balancer should be replaced. If you do have a failed balancer, don’t operate the engine because the imbalance and/or torsional forces on the crankshaft can cause damage to the crankshaft and main bearings. You can obtain an inspection/repair quote, and schedule the repair as you like, by simply visiting YourMechanic’s harmonic balancer repair service page and click on "Get a Quote". If you request this service, the responding certified mechanic will first inspect what you have and, if indicated, implement the required repairs and answer any questions that you might have. With regard to the ticking noise, that is almost undoubtedly valve train noise. A certain, minimal level of noise can occur on particular makes and models. Whoever performs the balancer inspection and repair, if required can evaluate that noise up close and let you know if it is normal or not. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

ANSWER : Hello there. Thanks for the detailed description on your inquiry – it really helps us out. Based on what you have indicated, my first assumption would be that you have a loose serpentine / drive belt or a pulley that is showing early signs of wearing out. When the noise happens during breaking and normal operation, it tends to be caused by a belt that is frayed or loose. As you accelerate, the belt will tighten naturally; which is why the sound might slow down during idle. If the belt and pulley’s have not been replaced within 40,000 miles or so, it’s probably due to be completed. Since it’s possible that this could be from a different source, it’s also a good idea to have a professional mechanic complete a car is making a noise inspection to verify the source of this noise before making repairs.

ANSWER : Hi there. Although it is hard to pinpoint the exact source of this noise via a video, it sounds a lot like an exhaust leak. When the exhaust manifold of exhaust tubes age, they are exposed to elements, creating weakness in the metal and eventually will crack or break. It is also possible that this sound is caused by cylinder head hardware that is loose (such as lifters or rocker arms) or not getting enough lubrication. Again, without being there it is impossible to know for certain, but you might want to have a professional mechanic complete a car is making a noise inspection to determine what is causing this issue.

ANSWER : Anything is possible with enough engineering. The changes you are looking at would take major structural changes and would definitely not be an easy job. You could possibly consult a manufacturing engineer to get more details on how this could actually be carried out and whether it would be feasible.
