A Guide to the 2000-2009 Audi TT Engine Valve Cover Gasket Set
Stop that burning oil smell and keep your TT's engine clean by fixing a common and crucial oil leak.
- A burning oil smell is the most common symptom of a leaking valve cover gasket on an Audi TT.
- For 1.8T engines, it is critical to also replace the cam chain tensioner gasket at the same time.
- Choose OEM-equivalent aftermarket brands like Elring or Victor Reinz for the best fit and longevity.
- Proper cleaning of all surfaces and using RTV sealant in the corners are essential for a leak-free installation.
Is Your Audi TT Leaking Oil? Check the Valve Cover Gasket
A leaking valve cover gasket is a very common issue on the 2000-2009 Audi TT, whether it has the 1.8T or 3.2L VR6 engine. 🎬 See how to replace the gasket on VR6 engine models. The constant heat from the engine causes the original rubber gasket to harden and shrink, breaking the seal. This allows oil to seep out, creating a mess in your engine bay and potentially causing other problems. If oil drips onto the hot exhaust manifold, it can create a fire risk.
Symptoms of a Bad Valve Cover Gasket
- Burning Oil Smell: This is the most common sign. When oil leaks from the valve cover, it often drips onto the hot engine block or exhaust parts, creating a distinct burning smell that you might notice inside or outside the car.
- Visible Oil Leak: You may see oil residue or grime built up on the side of the engine, just below the plastic engine cover. In more serious cases, you might see drips on the ground where you park.
- Oil on Spark Plugs or Ignition Coils: When you remove an ignition coil to check a spark plug, finding it wet with oil is a clear sign that the spark plug tube seals have failed. This can cause engine misfires.
- Low Engine Oil Light: A significant leak can cause your engine oil level to drop over time, possibly triggering the low oil warning light on your dashboard.
Pro Tip for 1.8T Engines
The 1.8T engine is also known for leaks from the cam chain tensioner gasket, which is located at the back of the valve cover. Since you have to remove the valve cover to access it, it is highly recommended to replace this gasket at the same time. Many kits include this extra seal.

You don't need to buy a genuine Audi part to get a quality seal. Several aftermarket brands make excellent gaskets for the TT, and some are even the original equipment manufacturer (OEM) for Audi.
Brand Quality Tiers
- Top Tier (OEM-Equivalent): Brands like Elring and Victor Reinz are often the original suppliers to Audi and Volkswagen. Choosing one of these brands ensures you get a part that fits perfectly and is made from high-quality materials designed to last.
- Quality Aftermarket: Fel-Pro and Beck Arnley are well-respected names in the aftermarket. They are known for producing reliable gaskets that meet or exceed OEM standards and are a popular choice for many mechanics.
- Value Tier: Brands like Apex and Elwis offer a more budget-friendly option. While they can provide a good seal, they may not have the same longevity or precise fit as the top-tier brands.
Common Ordering Mistake
The 2000-2009 Audi TT came with different engines (1.8T, 2.0T, and 3.2L VR6), and their valve cover gaskets are not interchangeable. Always confirm your specific engine type before ordering to ensure you get the correct part. The OEM part number for the popular Mk1 1.8T engine is 058198025A.

Frequently Asked Questions (FAQ)
Do I need to use sealant when installing the new gasket?
Yes, a small dab of RTV silicone sealant is required in specific spots. For the 1.8T engine, sealant should be applied at the sharp corners where the gasket goes over the camshaft bearing caps and around the half-moon seal for the cam chain tensioner. This prevents leaks in areas where the gasket alone might not seal perfectly.
Is replacing the valve cover gasket a good DIY job?
Yes, for many owners with basic mechanical skills, this is a manageable DIY project. The job mainly involves removing engine covers, ignition coils, and some hoses to access the valve cover bolts. The key is to clean the mating surfaces thoroughly and tighten the bolts to the correct torque specification, which is very low (around 7 ft-lbs or 10 Nm).

A set typically includes the main perimeter gasket and the inner spark plug tube seals. Some kits for the 1.8T engine will also include the half-moon cam chain tensioner gasket. It's important to replace all components in the set at the same time for a complete, leak-free repair.
Are there any recalls for this issue on the Audi TT?
No specific recalls were found for the 2000-2009 Audi TT related to the valve cover gasket itself. While Audi has issued recalls for other models concerning loose valve cover screws that could cause oil leaks and fire risk, these do not apply to the Mk1 or early Mk2 TT models.
