Great question—it’s always best to look into strange noises from your car! The most common reason for a Subaru making a ticking noise is from loose valves, worn injectors, or an exhaust leak.
Loose valves
The valves in your engine sit almost sideways to line up with the rest of the internals. If there’s insufficient space between components, the valves’ performance and noise levels will be affected. So, if your valves are making a ticking noise, they need to be tightened to the appropriate specifications for your engine.
Worn injectors
Fuel injectors run using extremely high-pressure ratings, and when placed at an angle for the boxer configuration, it requires them to work extra hard. This extra effort can cause more wear on the moving parts, which can develop into a ticking noise over time.
Exhaust leak
Because the layout of the boxer engine is unique, the exhaust pipes coming off the manifold are exposed to extreme temperatures, which can lead to the wearing of the metal materials and a subsequent exhaust leak. The exhaust coming out of the holes typically makes a rhythmic ticking noise. Sometimes you can even notice a smell coming out of the exhaust area.
