Tech Tip: Blown Head Gasket Symptoms, Causes and Fixes

Early detection prevents costly and time-consuming repairs
Head gasket issues are BY FAR the #1 problem our support team talks to customers about every day.

Since the head gasket has the most critical sealing job in the engine — to seal and protect the cylinders from coolant or engine oil infiltration to ensure maximum compression —  a blown head gasket can be crippling. When a head gasket leak is detected early, it often can be repaired chemically before it grows into a $1,500 to $3,000 problem.

How to spot a blown head gasket

Here’s a short list of customer complaints that are symptoms or signs of a blown head gasket:

A strong, sweet smell of heated coolant.
Low coolant level in the coolant reservoir, without visible leaks.

Why Would a Blown Head Gasket Cause Overheating?

The coolant in your vehicle’s engine serves an important purpose: it removes heat from your engine. This heat is created during the combustion process, as your engine fires and ignites the fuel and air mixture that makes the pistons move up and down. Some early engines didn’t have coolant and instead relied on air to cool the engine. Modern engines are much more high-performance than traditional air-cooled engines and require efficient cooling systems to keep them running at the right temperatures.

Your head gasket is an important component in your cooling system. It not only creates a seal between your engine block and head, it also channels coolant for optimal engine cooling. A blown head gasket can…

Is it Safe to Drive with a Blown Head Gasket?

The quick answer? No! A blown head gasket is a major problem for any engine, and one that costs quite a bit to fix mechanically. The head gasket is responsible for creating a seal between your engine block (the lower portion that houses the cylinders) and the head (the upper portion that contains the valves). Your head gasket also acts to channel engine coolant to keep your engine cool during operation. A blown or cracked head gasket can cause one of two problems:

It can allow coolant to escape from your engine. The result is a loss in coolant, which can lead to overheating of your engine if you drive it for any length of time.…

Will Stop Leak Products Damage My Car?

“Stop leak” tends to be a bad word in the automotive industry. Why? For three reasons:

There are inferior products out there that drag down the entire category as a whole, and
There are instances in which the product was installed improperly, or into problematic conditions (dirty or partially-clogged cooling systems, in particular)
The mechanical damage to the car is so bad that no chemical tool can fix it. In these cases, a customer tries a stop leak product, it doesn’t work, and proclaims it useless and ineffective.

Taking these point by point:

Our products have been, and continue to be, used in OEM applications. Brand new cars get our stuff installed at time of manufacture. Think about…

How to Fix a Blown Head Gasket Affordably

Blown head gasket repair has traditionally been considered an expensive headache. Typically, it would involve removing the head of your engine, pulling off the blown gasket, cleaning the block and head surfaces, reinstalling the gasket and bolting the head back in place — taking care to get the head bolts tightened properly. This all adds up, big time, and it’s not anyone’s idea of a fun weekend.

With today’s complex engines, mechanically fixing a blown head gasket involves removing many auxiliary parts and accessories. In the case of older engines, it can mean replacing tired old parts that are worn or broken. As you can imagine, this quickly becomes a long and expensive affair. A head gasket itself is expensive to purchase, and when you…
