The average pricing for a head gasket replacement is from $1200 to $3000+. With the average mechanic asking from $30 to $100+ per hour, it is easy to see how the labour intensiveness of a head gasket replacement can drive costs high. Show
The engine is a crucial part of any vehicle, and even small problems with it can lead to big headaches, repairs and damage. The engine is often described with that single word, yet it is made of several key areas, and the cylinder head is one of them. It is sealed with a head gasket, and if that fails it can cause the engine to fail. In this guide, we look at the signs of a head gasket problem, what it costs to get it replaced or repaired and how to choose the right mechanic for your needs. As noted earlier, most of the head gasket replacement cost can be attributed to labour. In fact, up to 70% of the cost can be blamed on the 10+ hours it takes for the work. And as is the case for so many vehicle repairs, the costs are going to vary based on such factors as:
Below are some standard costs for head gasket inspections prior to a replacement on common vehicles in Australia:
On Airtasker, mechanics are asking from $99 to $550 for inspections or head gasket replacements. What is the head gasket?The engine of any vehicle has an engine block and a cylinder head. Inside of the cylinder head are the fuel injectors and camshaft(s), while the block is where the pistons, valves and crankshaft are housed. Both the head and block rely on coolants and lubricants to function and keep the other systems running. However, the engine is clearly delineated by the different components and seals or gaskets between them. The head gasket is one of the most crucial of these seals and it is the point at which the engine block and the head connect. The head is where coolant and oil enter the engine, and as you might imagine, the head gasket faces a lot of pressures. After all, there is combustion inside of the engine and the pressures of the moving components. There are extremes of temperature, and other issues, and all of them are the reason that a head gasket is designed to be the “weakest link” and fail before other components. Why? When the engine overheats and blows the gasket, fluids mingle, and it becomes immediately obvious that something is wrong. What are the signs that I need a head gasket replacement?The signs that a head gasket failure has occurred are impossible to overlook. The engine overheats dramatically, there will be a lot of steam coming from the exhaust system, the engine will misfire or run badly. The engine may even fail. There will also be obvious signs that coolant and oil have blended, such as a milky and muddy fluid inside of the engine compartment, and exhaust gases may enter the cooling system while the engine is operating. Other signs include:
One or more such issues are clear signs of trouble and indicate that a repair or replacement is essential. Waiting to get this done can result in damage or even engine failure. How is a head gasket replacement done?When thinking about head gasket replacement costs and projects, keep in mind that the repairs themselves are simple. It is often a project that takes a great deal of time because so much disassembly and reassembly is required. The typical approach includes:
Keep in mind that a preliminary investigation of the issue is also part of any head gasket replacement task because it may not be the head gasket that is the problem. It could be a rocker cover issue, an exhaust issue, cooling system failure or another problem. Can I drive if the head gasket is blown?Though many say that you may be able to make it to a garage or short distance once the head gasket is blown or failed, it is unwise to do so. Every moment the engine runs without that tight seal, it increases the risks for serious damage to occur. Unfortunately, the signs may not be as obvious as many think they will and so you should stop the vehicle as soon as you notice an increase in the vehicle’s temperature, see even hints of smoke from the exhaust, notice a loss of engine power, or detect that distinct, sweet odour of burning coolant.
