Over time, your car’s engine will likely wear down and require replacement. In most cases, this means replacing the head gasket. However, not all head gaskets are created equal. If you’re not sure which one to replace, read on for some tips on how to determine which one is right for your car. ###
What is a Head Gasket?
A head gasket is a piece of metal that seals the engine’s combustion chambers. When it fails, the engine will not run and will require replacement. Head gaskets are typically replaced when they show signs of wear or when the failure occurs suddenly. When replacing a head gasket, be sure to replace all of the bolts and washers that hold it in place.
Types of Head Gaskets
There are many types of head gaskets and each requires a specific type of gasket replacement. Here are the most common types of head gaskets, their replacements, and why they fail:
1. Block Gasket: The block gasket is a rubber or metal seal that rests between the combustion chambers and the cylinder heads. It helps to keep oil and gas from mixing with air, leading to less ash and explosive emissions. A block gasket can fail if it’s unseated (by dirt, water, or heat), if it becomes contaminated with oil or gas, or if it’s overstressed due to high engine RPMs.
Block gaskets are usually replaced when they’re due for an overhaul (every 100,000 miles), but they can also be replaced at any time during the vehicle’s life. When replacing a block gasket, be sure to use a quality sealant like JB Weld or Permatex to help ensure a leak-free installation.
2. Head Gasket: The head gasket is aUS$1-$3 part that seals the top of the engine’s combustion chamber between the camshafts and the cylinder heads. It helps to prevent oil and gas from leaking out of the engine and into your car’s intake system (aka “blow by”). Head gaskets can fail for many reasons, including contamination from oil or gas, overheating caused by pistons hitting valves too hard (known as
