Engine Problems That Should Be Quickly Fixed

Posted on Posted in Blog

The engine holds all the power your vehicle makes. When running as it should, most model vehicles have no lag in performance and make virtually no sound at all. No noise and no delay is right for almost every newer car on the market. The only sounds you will be hearing are the sweet exhaust notes your vehicle produces, and anything else might be cause for concern.

Let’s take a look at some of the engine problems one could experience and why you shouldn’t put of having Subaru engine repair in Grass Valley.


A certain degree of ticking might be ordinary especially in semi-older vehicles. However, there are three reasons your Subaru might be producing the ticky noise. The first possibility is loose valves. Because the Boxer engine valves sit sideways, there is a smaller clearance for them to operate between the rocker and valve surface. If these are left loose and not corrected the valve could destroy the cylinder head. A simple trip to a Subaru repair Grass Valley shop can have them tightened down and resolve the ticking.

The second possibility to a ticking Subaru engine is worn fuel injectors. As with the valves, the fuel injectors are situated sideways and have to work harder to provide the constant spray levels needed to operate the engine. Because they have to work harder, they can become worn out as well as their movable components, creating an annoying ticking sound. Failure to have fuel injectors serviced soon can result in engine overheating or running at leaner conditions.

The last possibility for engine ticking is an exhaust leak. Exhaust leaks can make various sounds and are usually the culprit when odd engine sounds are heard. Because even the tiniest hole can produce noise in the exhaust system, and be hard to find, having a technician run a smoke test on your engine will be your best bet at finding the source. Exhaust leaks can affect idle, and engine performance.

The Dreaded Knock

For those that have heard engine knock it is unmistakable. Engine knock occurs in the lower end of the engine, where the crank, rods, and pistons reside. The cause can’t be determined until the engine is taken apart to see exactly where the damage is occurring. However, possible options as to why your Subaru engine is making a lower end knock is piston slapping, a rod knocking, or worn out wrist pins. No matter the reason for the sound, it is not advised to keep driving a vehicle that has developed the knocking sound. If you continue to run a motor with these problems, you will be purchasing a new engine.

While engine noises are a sign of great trouble, vehicles alert you to when something isn’t quite right through various sounds. Brakes, in particular, will make an annoying grinding noise when the pads are worn down to the indicator, and rotors will sound even worse.
