7 Symptoms of an Engine Problem

At the first indication of engine trouble, you'll want to bring your vehicle to the shop for an inspection. By acting quickly, you can potentially save yourself from needing very expensive repairs. Here are seven symptoms of engine trouble.

Power Loss

It's not automatically cause for concern if an older car with high miles has slowly lost some power over time. But an abrupt and major loss of power is a sign of serious trouble, such as problems with pistons.

Check Engine Light Comes On

When the check engine light illuminates, it doesn't always mean that engine failure is looming. But it's still wise to get to the shop for computerized diagnostics so that any developing problems can be identified and addressed before they get worse.

Knocking Noise

Low oil could lead to insufficient lubrication, which could result in metal-on-metal contact that causes a knocking sound. Another reason a knocking sound may emerge is if the air-fuel mixture ignites on its own rather than via spark plugs, which is something that should be taken care of promptly.


If your oil level gets dangerously low, then friction could cause vibrations that stem from your engine.


Overheating can cause major problems, such as a cracked engine block. To prevent overheating, it's important that your cooling system stays in excellent condition. Leaks in the cooling system are common causes of overheating and should be fixed quickly.

Discolored/Excessive Exhaust Smoke

You can look at the exhaust smoke's color to get a hint about the underlying problem. Blue-tinged smoke suggests that oil is leaking. Black smoke is an indication that you're burning too much fuel. White smoke is a sign of a coolant leak.

Engine Stalls when Idling

There's a good chance that a fuel delivery problem is to blame for this. Because you could be put in harm's way if your car stalls in traffic, it's important that fuel delivery issues are fixed as soon as possible.

If you need engine repair, be sure to bring your vehicle to an experienced mechanic. For engine repair in Austin, TX, contact the experts at Austin Auto Repair at (512) 865-6217.
