How To Fix A Noisy Subaru Engine

Let’s be honest: no one likes a noisy Subaru. But instead of getting upset, you should figure out what’s making your Subaru engine noisy so you can fix it! Luckily, there are many different reasons why a car makes noise. Here are some things that could be causing your car to make noise and how to fix them:

Inspect The Air Intake Duct

The air intake duct is a tube that connects the air filter to the engine. It can become clogged with dirt and dust over time, making your engine louder when you start it. To check whether or not your air intake duct is causing noise, first remove the air filter from its housing on top of your engine. If there is large dust and dirt in this area, then you have a noisemaker on your hands (and maybe even some clogged injectors). If you need to clean out this area, use compressed air or an old toothbrush for the best results!

Check Out The Air Filter For Dust And Debris

The air filter is a crucial part of your Subaru’s engine, ensuring that only good air goes into the cylinders. If the air filter is dirty or clogged with debris, such as mud or dust, it can cause your car to run poorly and even stall out on you.

Checking the condition of your car’s air filter is easy: all you need to do is look at it. If your car has been sitting for a while without being driven much, make sure that there isn’t any dirt or dust in there first—this will help ensure that when you’re driving again later on in life (if ever), everything runs smoothly!

Make Sure Nothing’s Touching The Serpentine Belt

The serpentine belt is responsible for driving many of your engine’s accessories. Make sure nothing is touching or rubbing against the belt, which could cause it to slip or break. Check that the belt isn’t damaged (look for cracks), and make sure that it’s not rubbing against any pulleys or other parts (like the radiator fan).

Check To See If Your Oil Is Low

If your Subaru car is making a loud noise and you haven’t checked your oil lately, it could be a good idea to do so. To check the oil level, first park the car on a flat surface. Then open the vehicle’s hood and locate where you would fill up with gasoline (or diesel). You should see an oil dipstick attached to a metal rod that sticks out of this location. If you are still looking for this rod/dipstick combination right away, look around for any other hoses leading into or near this spot.

When removing the dipstick from this location, remember not to touch any part of it with bare hands because some oils can irritate if they come into contact with skin surfaces such as fingers or palms. Instead, use some paper towels or cloths to avoid touching them directly, especially if there are signs that someone has possibly done so before (i.e., grime buildup).

In Extreme Cases, Replace The Talcum Powder In Your Engine’s Oil Cap

If you’ve tried everything else and still have a noisy engine, it’s time to replace the talcum powder in your oil cap. This isn’t just something people do for fun; talcum powder keeps the oil plug from sticking, preventing it from being pulled out without first loosening it. Talc can also help keep your engine clean by absorbing dirt and moisture that would otherwise be sucked into the crankcase.

To replace your current talc with new stuff, hold the oil cap upside-down over a bowl of water (to catch any spillage) and remove its screw using an adjustable or box-end wrench. Then add some fresh talc through a funnel before replacing both components with their respective threads to create an airtight seal between them again! Now you’re good as new!


Fixing a noisy Subaru engine can be a frustrating experience, but it doesn’t have to be. You can prevent any future problems by following the above simple steps to diagnose and repair your car when it starts making noise.

Take care of your car so that it continues running smoothly and quietly.
