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.
Why Is a Blown Head Gasket So Expensive to Repair?
A blown head gasket is near the top of the list of most expensive car repairs and can be estimated anywhere between $1300 and $1800 according to Repair Pal. This is, of course, a very broad estimate based on the average for many different vehicles so your costs may be even higher depending on the kind of vehicle you drive. The actual parts for a head gasket job can be as little as 10% of the total cost of the job, so the majority of the cost to replace a blown head gasket is in the labor.
How To Replace A Head Gasket (a.k.a. Labor Costs)
The high labor costs have most to do with the location of the head gasket. Your head gasket, or gaskets, sit just about in the middle of your engine so getting to them is no easy task. And require removing a lot of peripheral equipment like the alternator and power steering pump, along with the intake and exhaust manifold. Besides being time consuming, there’s a good chance that some of the bolts or nuts holding this equipment on will be frozen or rusted making removal difficult. Lastly, there are often lots of sensors and wiring around the manifolds and accessories that need to be removed and reinstalled correctly adding to the complication of the job.
Once you’ve removed all the accessories, wiring and hoses, removing the head itself is complicated and requires a good understanding of the engine to remove and replace properly. Whether you’ve got an overhead cam style engine or a pushrod style engine the timing needs to be set before and after head removal to make sure there isn’t any damage to the valves or pistons and to help everything run smoothly upon reassembly. With the head removed it’s important to properly inspect the head and block deck to make sure there is no damage to either of those otherwise installing a new head gasket won’t actually seal your leak. These complications add to both the amount of time required to do the job as well as the skill of the mechanic needed to do them which also contributes to the high cost to repair a blown head gasket.
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 the thermostat, water pumps, timing belts, engine coolant, engine oil, and other gaskets like the 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.
