What Is Timing Cover Gasket Replacement?

A timing cover is in place to protect your vehicle’s timing chain, timing belt, or cam belt from grime and road debris. The timing chain controls the rotation of the crankshaft and camshaft in an internal combustion engine. As long as these are spinning, the valves inside the engine will open and close as they should. If your timing cover gasket becomes damaged, you may notice oil leaking. Replacing the timing cover gasket as soon as possible is vital to keeping your vehicle running properly.

What Does a Timing Cover Gasket Replacement Include?

There are several steps to replacing a timing cover gasket. First, the vehicle needs to be in the park and then jacked up with the rear wheels secured with wheel chocks. Some cars provide easy access to the timing cover, but others require removal of numerous components even including the radiator and water pump in some instances. The drive belt needs to be removed to access the timing cover, which is then easily removed to access the gasket.

A new seal must be set in place, and then the timing cover can be placed to install a new timing cover gasket. There are additional steps for certain vehicles specified in your repair manual.

What Happens if You Don’t Replace Your Timing Cover Gasket?

If your timing cover gasket becomes damaged, it’s essential to replace it immediately to prevent further engine damage. When it first begins to fail, you can drive your vehicle for a short period, but an engine oil leak will start almost immediately. This puts your engine and all of its components at risk. Don’t drive around with a bad timing cover gasket more than necessary. 

How Often Should You Replace Your Timing Cover Gasket?

Most cars have a recommended timing belt/chain replacement by 100,000 miles (sometimes sooner), but you should replace the timing cover gasket if it’s visibly leaking oil. If it’s not leaking, the only time you’ll need to replace the timing cover gasket is if you’re replacing the timing belt/chain.

Common Symptoms You Need to Replace Your Timing Cover Gasket

Some signs may indicate that your timing valve gasket needs to be replaced. Ignoring these signs can cause further problems with your engine. Some of the common symptoms that you need to replace the timing valve gasket include:

  • Engine oil is leaking from your timing cover. You may notice this as oil leaking out the bottom of your car. Leaking oil is always an indicator that something has gone wrong. Determining the cause sooner rather than later will help avoid additional damage.
  • Your vehicle’s check engine light comes on. A bad timing cover gasket could affect the engine’s oil pressure, which may set a diagnostic trouble code (DTC) including P0521.
