Guide to the Engine Valve Cover Gasket Set for 1997-2001 BMW 528i
Stop the burning oil smell and keep your E39's engine clean by choosing the right valve cover gasket set.
- Verify if you have the M52 (97-98) or M52TU (99-01) engine, as the gaskets are different.
- Always inspect the plastic valve cover for cracks or warping; a new gasket won't fix a damaged cover.
- Choose a high-quality aftermarket brand like Reinz or Elring for a durable, long-lasting seal.
- The replacement set must include the main gasket, spark plug well seals, and 15 bolt grommets.
Engine and Year Model Differences
It is critical to know which engine your 528i has. The valve cover gasket is different for each one.
- 1997-1998 BMW 528i: Uses the M52 engine (single VANOS).
- 1999-2001 BMW 528i: Uses the M52TU engine (dual VANOS).
Always verify your vehicle's production date and engine type before ordering. Using the wrong gasket will result in significant oil leaks.
Common Failure Symptoms
When the valve cover gasket fails, the signs are usually obvious. Heat and age cause the rubber to become hard and brittle, breaking the seal. Here’s what to look for:
- Burning Oil Smell: This is the most common symptom. Oil leaks from the gasket and drips onto the hot exhaust manifold, creating a sharp, burning smell that often enters the cabin when you're stopped.
- Visible Oil Leaks: You will see wet, dark areas of oil around the edge of the valve cover, especially on the passenger side of the engine. The oil can attract dirt and grime, making the engine look messy.
- Oil in Spark Plug Wells: A failing gasket set allows oil to pool in the spark plug tubes. This can ruin the spark plugs and ignition coils, leading to engine misfires, a rough idle, and the Check Engine Light coming on.
- Low Engine Oil: A persistent leak will cause your engine oil level to drop over time, requiring frequent top-offs.
Inspect the Valve Cover and PCV System
Before replacing just the gasket, inspect the plastic valve cover itself. On M52TU engines especially, the valve cover can become brittle, warp, or crack from years of heat cycles. A new gasket cannot seal a cracked or warped cover. If you see cracks or if the cover is warped, you must replace the entire valve cover assembly. Also, a failing Crankcase Ventilation (CCV) system can increase pressure inside the engine, causing gaskets to fail. 🎬 Watch this guide on common BMW oil and vacuum leaks. It is often recommended to service the CCV system when replacing the valve cover gasket.
Choosing an Aftermarket Gasket Set
For a component like this, quality matters. A cheap, poorly made gasket can fail quickly, forcing you to do the job all over again. Here is a breakdown of common aftermarket brands:
- Reinz (Victor Reinz): Often an Original Equipment Manufacturer (OEM) for BMW, Reinz gaskets are widely considered a top-tier choice for quality and fitment. However, some users have reported issues, suggesting the possibility of counterfeit parts or installation error.
- Elwis / Elring: Elring is another OEM supplier for BMW and is highly recommended for its fit and durability. Gaskets from Elwis are also well-regarded and provide a reliable seal.
- Apex: This brand is generally positioned as a budget-friendly option. While they claim to meet or exceed OEM standards, user reviews are mixed. For a critical seal on a BMW, it may be wiser to invest in a more proven brand to avoid premature failure.
Installation Pro-Tip
When installing the new gasket, make sure the surfaces on the cylinder head and valve cover are perfectly clean. Use a small dab of RTV sealant at the sharp corners where the timing cover meets the head. Always replace the 15 rubber grommets on the valve cover bolts to ensure proper, even torque and prevent leaks. Do not overtighten 🎬 Follow this step-by-step video to replace your valve cover gasket. the bolts, as this can crack the plastic valve cover.

Frequently Asked Questions (FAQ)
Do I need to use sealant on the whole gasket?
No, do not apply sealant to the entire gasket. Only apply a small amount of gasket maker (RTV) to the semi-circular cutouts at the rear of the engine and where the front timing cover meets the cylinder head.
What are the little rubber washers (grommets) for?
The small rubber grommets seal the valve cover bolts. They are essential for applying even pressure and preventing oil from leaking through the bolt holes. These almost always come with a quality gasket set and must be replaced.
My new gasket is still leaking. What went wrong?
If a new, quality gasket is leaking, the most likely cause is a cracked or warped plastic valve cover. It could also be due to improper surface cleaning or incorrect bolt tightening. Another possibility is a clogged PCV/CCV system creating 🎬 Learn what mistakes to avoid during your gasket installation. excess crankcase pressure.
Are there any recalls for this part?
There are no specific recalls for the valve cover gasket on the 1997-2001 BMW 528i. However, there is a major "Do Not Drive" recall for defective Takata airbags affecting 2000-2003 models that owners should be aware of.
