Ford Mustang Engine Timing Cover Gasket Set: A Guide for 2006-2017 Models
Chasing an oil leak at the front of your Mustang's engine? This guide is for you.
- The main symptom is an oil leak from the front of the engine; confirm it's not a valve cover leak, especially on 2015-2017 5.0L models.
- Replacement is a very labor-intensive job (6-10+ hours) and is not recommended for a DIY beginner.
- The high labor cost makes using a quality gasket from a brand like Victor Gaskets or Cometic a smart investment.
- Always replace the front crankshaft seal and inspect the water pump at the same time to save on future labor costs.
Is Your Mustang's Timing Cover Gasket Failing?
The most common sign of a bad timing cover gasket is an oil leak from the front of the engine. You might see oil drips on the ground under the front of your car or notice oil residue on the engine block, oil pan, or front crossmember. Sometimes, the serpentine belt can fling the leaking oil around, making it difficult to pinpoint the exact source. It's crucial to clean the area with a degreaser and then run the engine to find the fresh leak.
Check for Coolant Leaks Too
While oil leaks are most common, a faulty timing cover gasket can also cause coolant leaks on some models. This happens if the gasket fails around the water pump passages that run through the timing cover. If you see a coolant leak from the front of the engine, a pressure test can help confirm the source.
A Common Point of Confusion: Timing Cover vs. Valve Cover Leaks
For 2015-2017 Mustang GT models with the 5.0L Coyote engine, there is a Ford Technical Service Bulletin (TSB 19-2309) for oil leaks from the valve cover gaskets. These gaskets can warp from heat, causing a leak that can easily be mistaken for a timing cover leak as the oil runs down the front of the engine. Before committing to a costly timing cover repair, carefully inspect the valve covers, which are located on the top of the engine, for any signs of oil seepage.
Choosing the Right Aftermarket Gasket Set
When replacing the timing cover gasket, you have options. The quality of the gasket is important, as the labor to replace it is the most expensive part of the job. You don't want to do it twice.
- Premium Performance (Cometic Gasket): Cometic is known for high-performance and racing applications. Their gaskets are top-tier, often made from multi-layered steel (MLS). This is an excellent choice for modified or high-horsepower engines but may be unnecessary for a stock daily driver.
- OEM Quality (Victor Gaskets): Victor Reinz is a well-respected brand that often manufactures parts for original equipment suppliers. Their gaskets are considered a reliable, high-quality choice for a stock replacement and are engineered to meet or exceed factory specifications.
- Standard Aftermarket (Fel-Pro): Fel-Pro is another widely trusted brand in the aftermarket and is a common choice for many mechanics and DIYers for its reliability and availability.
Pro Tip: This is a labor-intensive job. While you have the timing cover off, it is highly recommended to also replace the front crankshaft seal (also called a front main seal) and inspect the water pump. These parts are accessible during the repair and are inexpensive to replace at the same time.

Frequently Asked Questions
Is this a good DIY project?
For most owners, no. Replacing the timing cover gasket is a difficult and time-consuming job rated at 6-10+ hours. It requires draining fluids, removing the serpentine belt, water pump, harmonic balancer, and multiple accessories. Special tools, like a harmonic balancer puller, are required. This job is best left to experienced mechanics.
Will a bad timing cover gasket cause a Check Engine Light?
It's unlikely to directly cause a Check Engine Light. However, a significant oil leak could potentially lead to other issues that might trigger a light, such as oil contaminating sensors. In rare cases, a leak creating a vacuum loss could also trigger a light.
What happens if I don't fix it?
A small leak might seem harmless, but it will only get worse. Ignoring it can lead to low engine oil levels, which can cause significant internal engine damage. Leaking oil can also damage rubber hoses and belts, leading to more repairs.
Are there any recalls for this issue?
No, there are no NHTSA recalls for timing cover gasket leaks on the 2006-2017 Ford Mustang. This type of repair is considered general maintenance and wear. While there is a TSB for valve cover leaks on 2015-2017 5.0L models, it is not a recall.
