How Do You Know It’s Time to Replace Your Engine’s Head Gasket?

Subaru Service

If you want your Subaru vehicle to stay in great shape for as long as possible, you need to give it the care it needs. One key element of this is being vigilant and addressing issues as soon as they arise, particularly when this involves an essential part like a Subaru head gasket. Here, Casey Subaru goes over this component and the warning signs to look out for.

What is a Head Gasket?

A head gasket is a water- and airtight seal between the engine block and cylinder head. It plays a major role in combustion, as it helps maintain compression and ensures that the oil and coolant are properly circulated and that they don’t contaminate each other.

Signs of a Bad Head Gasket

If something is wrong with your head gasket, there will be signs, some of which may be more obvious than others. If you notice any of these things, seeking Subaru service is vital.

Loss of Power

When a head gasket isn’t working correctly, this can affect compression, which will hamper your vehicle’s power production. Poor acceleration and a rough idle are other indications.

Overheating Engine

A malfunctioning head gasket can allow coolant to escape, and this affects an engine’s ability to regulate its temperature.

White Smoke

Any smoke coming from your exhaust is a problem, and if it’s white, this could mean that the coolant has leaked into the combustion chamber.

Milky Oil

If you suspect any issue with your head gasket, check out the oil. If it’s milky, this is a clear indication that coolant has gotten in there.

External Leak

Another thing to look for under your hood is any sort of leak in your engine. If you spot either oil or coolant seeping out, this is obviously a problem.

Certain Engine Work

This is a rare case, but if you’ve had engine work performed that required the removal of the cylinder head, the head gasket should have been replaced and not reused. Automotive gaskets are designed to be single-use, and will be ineffective if you try to reuse them.
