Honda Pilot Engine Valve Cover Gasket Guide for 2010-2016 Models
Leaking oil and smelling something burning? Your Pilot's valve cover gasket set might be the culprit.
- A burning oil smell is the most common symptom of a failed valve cover gasket on a 2010-2016 Pilot.
- It is highly recommended to replace both front and rear gaskets at the same time, along with the spark plug tube seals and bolt grommets.
- Accessing the rear gasket requires removing the intake manifold, making the job significantly more complex than the front gasket alone.
- High-quality aftermarket brands like Fel-Pro offer a reliable and cost-effective alternative to OEM parts for this repair.
Symptoms of a Failing Valve Cover Gasket on a Honda Pilot
When the valve cover gaskets on your Pilot's J35 V6 engine start to fail, they give a few clear signs. The rubber becomes hard and brittle over time and can no longer create a proper seal. Here’s what to look for:
- Burning Oil Smell: This is the most common symptom. As oil leaks from the gasket, it drips onto the hot exhaust manifolds below, creating a distinct and unpleasant burning smell, especially noticeable after driving.
- Visible Oil Leaks: You may see oily residue or grime collecting on the valve covers, especially on the front cover which is easier to see. The rear cover, near the firewall, can also leak but is harder to inspect without a mirror or taking things apart.
- Oil in Spark Plug Wells: If the tube seals fail, oil will pool in the spark plug tubes. This can lead to a check engine light, a rough running engine, and misfire codes (like P0300-P0306) because the oil damages the ignition coils and spark plugs.
- Low Engine Oil Level: A significant leak will cause your engine oil level to drop between oil changes, requiring you to top it off frequently.
Pro Tip: Check the PCV Valve
A clogged Positive Crankcase Ventilation (PCV) valve can cause pressure to build up inside the engine. This excess pressure can force oil past even a good gasket, causing leaks. It's a good idea to inspect or replace the PCV valve 🎬 Watch a full walkthrough of the gasket and PCV replacement. when you replace the valve cover gaskets.
Choosing the Right Aftermarket Gasket Set
For the 2010-2016 Honda Pilot, you don't necessarily need to buy the expensive OEM (Original Equipment Manufacturer) part from the dealer. Several reputable aftermarket brands offer high-quality gasket sets that meet or exceed OEM specifications. Aftermarket kits are often designed for the "real world" repair environment, where sealing surfaces might not be perfectly clean or flat.
Aftermarket Brand Tiers
- Top Tier (Excellent Quality): Brands like Fel-Pro and Mahle are highly regarded by professional mechanics and DIYers. Fel-Pro, in particular, is known for engineering gaskets specifically for repair scenarios and often improves on the original factory design. They are a safe and reliable choice.
- Good Quality (Reliable Alternatives): Beck Arnley, Victor Reinz, and Elring are also solid options. Beck Arnley often sources parts from the original OEM suppliers and repackages them. Victor Reinz and Elring are also well-respected gasket manufacturers.
- Budget-Friendly: While there are cheaper, lesser-known brands available, sticking with a recognized brand is recommended for a critical part like a valve cover gasket to avoid having to do the job twice.

Frequently Asked Questions
Is replacing the valve cover gasket a DIY job?
For a handy owner with the right tools, yes. The front valve cover is relatively easy. However, the rear valve cover is much more difficult because the upper intake manifold must be removed to access it. This adds significant time and complexity. A novice DIYer might find the rear gasket challenging, taking around 3 or more hours. If you're not comfortable with that level of disassembly, it's best to leave it to a professional.
🎬 See how to remove the intake manifold for this repair.Do I need to use sealant (RTV) with the new gasket?
The main gasket itself is installed dry into the channels on the valve cover. However, it is standard practice to apply a small dab of RTV sealant at the sharp corners where the timing cover meets the cylinder head to prevent leaks in these critical spots.
Should I replace both front and rear gaskets at the same time?
Yes. If one gasket has failed due to age and heat, the other is likely not far behind. Since replacing the rear gasket requires removing the intake manifold, it makes sense to replace both at the same time to save on future labor costs.
Are there any recalls for this issue?
As of early 2026, there are no specific recalls from Honda or NHTSA for leaking valve cover gaskets on the 2010-2016 Honda Pilot. This is considered a normal wear-and-tear maintenance item.
