7 Possible Signs of a Bad Head Gasket - Service Questions serving Sacramento, CA

A blown head gasket is no fun, and it needs to be replaced as soon as possible. Driving with a bad head gasket can cause massive damage to your engine, including warping. Fortunately, a blown head gasket will give you some conspicuous signs. Seven of them are listed below--but if you have any other sneaking suspicions that something may be amiss, we recommend contacting the expert technicians at Shingle Springs Subaru.

 

7. Low Coolant

If the coolant in your vehicle is lower than it should be, a head gasket may be the culprit. This can be true whether there's a noticeable external leak or not, so be sure to keep an eye on coolant levels so you won't be taken by surprise.

6. Cylinder Misfire

Cylinders can misfire for a variety of reasons, and a bad head gasket letting oil and/or water into the cylinder is one of those reasons. If your engine is misfiring, be sure to bring it to a service center, where factory-trained technicians can get to the cause of the problem.

5. Blue Exhaust Smoke

There are many reasons the smoke coming from your exhaust system may be blue. While a bad head gasket may not be the primary culprit, it's helpful to have it inspected to make sure.

4. White Exhaust Smoke

Blue isn't the only troublesome exhaust color. It's normal for white emissions to come from your engine's tailpipe when it first starts up. However, if this continues even after your engine is warm, it may be a sign of a bad head gasket.

 

3. Bubbles in the Radiator

If the coolant in the system is bubbling, gases could be getting into the system through a blown head gasket. The bubbles will often be present even when the engine is cool.

2. Overheating Engine

If the head gasket in your vehicle is bad, the coolant that keeps your engine at the right temperature can fall to dangerously low levels, making it easier for your engine to overheat.

1. Milky Engine Oil

A blown head gasket will allow oil and coolant to intermingle, giving it a milky-brown look. While some of these other symptoms may have other causes, milky oil is almost always caused by a bad head gasket--so if your oil looks like this, don't hesitate to bring your vehicle in for repair!
