How to Fix Engine Block Cracks and Leaks

A leak or crack in your engine block can lead to a messy, intimidating affair. You’re probably thinking about the complexity and cost involved in repairing or replacing your engine and how you’ll have to live without your vehicle for an extended period. Thankfully, there’s a better way to fix engine block cracks and leaks. With Bar’s Leaks, you can take care of leaks without physically replacing any components. Catching the problem before it becomes too severe is key.

We have specially formulated our products to address the source of leaks and stop them, permanently. Your engine block can leak for different reasons, including:

  • Cracks and damage due to wear, overheating or an accident
  • Leaks between the block and head because of a blown head gasket
  • Oil and coolant leaks because of worn or broken seals and gaskets

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 allow coolant to either enter your engine, where it is burnt off or leaks out of your engine onto the ground. In both cases, you can starve your engine of the coolant it needs, allowing overheating and permanent engine damage. Blown head gaskets aren’t something you want to ignore for any length of time.

A head gasket leak needs to be repaired as soon as it’s detected. There are several signs that you have a blown head gasket: Read More

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. Hot escaping coolant can also cause burns if you’re checking under the hood and can also start a fire, which is why a blown head gasket needs to be treated quickly.
  • It can allow coolant to enter your cylinders. If coolant is mixed in with your engine oil and fuel, the result is the characteristic white smoke you see coming from the tailpipe of a car with a blown head gasket. Too much coolant in your cylinders can lead to severe engine damage quickly, as it keeps your engine oil from lubricating properly.

Why is my Car Leaking Oil When the Engine is Cold?

It’s easy to assume that engine oil leaks will be more prevalent when the engine is running. When an engine is running, oil pressure increases, which makes it more likely that engine oil will leak. Quite often, however, we can see engine oil leaks that occur when a vehicle is parked and the engine is cold. Here’s why. Read More

Why is my Car Leaking Oil When Parked on a Hill

Depending on the cause and location of an engine oil leak, you may not detect it all the time. Sometimes an oil leak will only present itself when you’re parked on an incline. Even if this kind of leak doesn’t appear all the time, you need to take action once you notice it. Any engine oil leak means you’re losing oil and you risk running your engine without enough oil for lubrication and cooling. Oil leaks are bad, and we’ve seen what happens when they’re ignored for too long. Hint: nothing good. Read More
