The most common reasons a Subaru Ascent engine makes a ticking noise are low oil level or pressure, an issue with the ignition system, or an exhaust leak.
  • Exhaust Leak: A damaged exhaust manifold or a loose connection in the exhaust system can cause an exhaust leak, resulting in increased noise and potential loss of engine power.

How much does it cost to fix a Subaru Ascent engine makes a ticking noise?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

An engine leaking oil does not always make a puddle on the ground. A burning smell may be noticed from the front of the vehicle after driving. This is because engine oil leaks may fall onto hot engine components, especially the exhaust manifold, and burn off before making it to the ground. This poses a risk to the engine because the leak going unnoticed may deplete the engine oil reserve, and lead to an oil starvation issue. Some engine oil leaks only occur while the engine is running, so the leak may be larger than the small spot on the ground makes it seem.

Noises can be accompanied by many annoying or worrisome sensations. Consider the noise of grinding brakes, the noise sounds much like the brake pedal and steering wheel feel. This is important, as random noises can be difficult to replicate without knowing when the sound occurs, what must be done to make the sound, and what sound it is. Any professional technician can replicate and diagnose most noises, but to ensure the vehicle is more quickly diagnosed, make sure you tell your technician these three pieces of information.

The engine oil pressure warning light will come on if the engine oil pressure is low, or if the oil pressure sensor is faulty. In either case, engine power may be reduced significantly. The check engine light may also illuminate, and an on-board diagnostic (OBD) trouble code will be stored in the vehicle's computer.

Troubleshooting Ticking Noise in a Subaru Ascent

When troubleshooting a ticking noise in your Subaru Ascent, start by checking the oil level and pressure, as low oil can lead to significant engine noise and damage. Ensure the engine is off and cool before checking the dipstick for oil levels. If the oil is low, top it up with the recommended type to see if the noise resolves. Next, inspect the ignition system, including spark plugs and wires, as faulty components can create ticking sounds. If the noise persists, examine the exhaust system for leaks, which can often produce a ticking sound, especially when the engine is cold. Additionally, if you experience a clicking noise when starting the vehicle, consider testing the battery, as a weak battery can cause both starting issues and ticking noises. Lastly, pay attention to how the vehicle behaves during acceleration; if it stutters, further investigation into the turbo system may be necessary. Regular maintenance is key to preventing these issues, so adhere to your vehicle's service schedule to keep everything running smoothly. If these steps do not resolve the ticking noise, it may be time to consult a professional mechanic for a more thorough diagnosis.

Troubleshooting Engine Ticking Noise in a Subaru Ascent

When dealing with engine ticking noise in your Subaru Ascent, it's crucial to understand the common problems that could be causing this issue. One of the primary culprits is low oil level or pressure, which can lead to insufficient lubrication of engine components, resulting in a ticking sound. Regularly checking and maintaining your oil levels is essential for preventing this problem. Additionally, ignition system issues can contribute to engine noise; ensuring that spark plugs and ignition coils are in good condition can help mitigate this. Another potential source of ticking is an exhaust leak, which can often be identified by inspecting the exhaust system for any visible cracks or loose connections. If you hear clicking noises when starting your vehicle, it may indicate a weak battery, so testing and replacing the battery if necessary is advisable. Furthermore, worn pulley bearings can create ticking sounds, so checking the condition of the tensioner and other pulleys is important. Lastly, inspect the engine and radiator fans for any damage or loose components, as these can also produce unwanted noise. By addressing these common issues promptly, you can maintain the performance and longevity of your Subaru Ascent.

Why is There a Ticking Noise in My Subaru Ascent Engine?

When you hear a ticking noise in your Subaru Ascent engine, it’s crucial to understand that this could indicate underlying problems that require immediate attention. Low oil levels or pressure can lead to insufficient lubrication, causing engine components to wear prematurely, which may result in costly repairs if not addressed. Additionally, issues with the ignition system or an exhaust leak can not only contribute to the ticking sound but also affect your vehicle's performance and fuel efficiency. A failing drive belt idler pulley can create a noticeable chirping noise, signaling that it may need replacement to avoid further complications. Furthermore, loose valves in the engine head can lead to more severe engine damage if left unchecked. Therefore, it is essential to diagnose and resolve the source of the ticking noise as soon as possible to prevent potential safety risks and significant damage to your vehicle. If you are uncertain about the cause, consulting a qualified mechanic is advisable to ensure your Subaru Ascent remains in optimal condition.
