When most of us hear the phrase “blown head gasket” we see dollar signs flash before our eyes. If you haven’t experienced it with one of your vehicles, you’ve probably had a friend with an older car get the report that they have a blown head gasket and a repair bill that makes you want to go get a second job, or start riding a bike. But why is a blown head gasket so expensive to repair? In this article we’ll talk through the process of replacing a head gasket and try to understand why it is such an expensive repair.
This article on the 4 most expensive car maintenance items includes a blown head gasket as one of the top 4 most expensive problems you can have with your vehicle. It estimates that you should pay between $1200 and $1600 dollars for a head gasket job on your vehicle. Depending on the vehicle you drive, these estimates are reasonable, but for some simple vehicles with smaller engines you might pay as little as $600 or as much as $2500 for a complicated vehicle. The complication isn’t in the head gasket itself. A head gasket can cost as little as $10 for a small 4 cylinder engine or as much as $400 for a performance or specialty head gasket with most closer to $75 to $100.
The majority of the cost, and deviation in costs, for a head gasket job comes in the labor. The head gasket sits between the engine’s cylinder head and engine block. In order to replace this gasket you need to remove a significant portion of the engine and its accessories. Besides removal, putting the engine back together is not simply a matter of replacing components and tightening bolts. Many of the components that need to be reattached after a new head gasket is installed require specific torque settings to ensure a proper seal and no damage to be done. Also, removal of the cylinder heads on any engine means you have to make sure when it is reassembled that the engine is timed correctly to make sure further engine damage does not occur. All of these reassembly complications make it a slow and painstaking process that should only be done by very experienced technicians.
These complications can be enhanced based on the vehicle you drive. If you have a V6, V8 or boxer engine, then your engine has 2 head gaskets that need to be replaced which will add to the cost of the job. Also, if you have a front wheel drive vehicle it can add to the cost of the repair as the mechanic will have less room to work making the job more difficult, take longer, and ultimately be more expensive.
Lastly, when you disassemble that much of an engine, there often are some other parts that are worth replacing while you have the engine taken that far apart. Things like thermostats, water pumps, timing belts, engine coolant, engine oil, and other gaskets like intake manifold and exhaust manifold gaskets are all options to be replaced during a head gasket repair. Deciding to add these replacement items is often smart as they can save you from future repairs and costs, but can significantly increase your blown head gasket repair cost. Lastly, if you have a badly blown head gasket it may even require machining of your engine block or head which is complicated work only done by specialty machine shops. If this is required on your vehicle you can add hundreds of dollars to your repair costs.
All of these factors can add up and make your blown head gasket repair bill very high, and for good reasons. The good news in all of this is that you do have another option.
