A Guide to the Engine Valve Cover Gasket Set for the 1999-2004 Saab 9-5
If you smell burning oil or see leaks on your Saab 9-5's engine, your valve cover gasket is the most likely cause.
- A leaking valve cover gasket is extremely common on the 1999-2004 Saab 9-5, with a burning oil smell being the top symptom.
- You MUST inspect the PCV system. A clogged PCV system is a primary cause of gasket failure on these engines and a new gasket will fail again if the PCV issue isn't fixed.
- Choose a quality aftermarket brand like Elring or Victor Reinz for a reliable, long-lasting seal.
- This is a very manageable DIY job that requires basic tools like T30 and T40 Torx bits and about one to two hours of time.
Is Your Saab 9-5 Leaking Oil? Check the Valve Cover Gasket First
A leaking valve cover gasket is one of the most common oil leaks on the 1999-2004 Saab 9-5. Over time, the rubber gasket gets hard and brittle from engine heat and exposure to oil, causing it to lose its seal. The good news is that this is a relatively simple and inexpensive part to replace.
Symptoms of a Failing Gasket
Look for these clear signs of a bad valve cover gasket:
- Burning Oil Smell: This is the most common symptom. Oil drips from the leaking gasket onto the hot exhaust manifold, creating a sharp, burning smell.
- Visible Oil Leaks: You will see oil residue and grime collecting on the engine, specifically around the seam where the silver valve cover meets the engine block. You might also see oil spots on the ground where you park.
- Oil in Spark Plug Wells: When you remove the black Direct Ignition Cassette (DIC) from the top of the engine, you may find oil pooled around the spark plugs. This can cause engine misfires.
- Low Engine Oil: A significant leak will cause your engine oil level to drop over time, which can lead to serious engine damage if not addressed.
A Critical Note on Saab's PCV System
Before you replace the gasket, you must understand the Positive Crankcase Ventilation (PCV) system on your Saab. A clogged or failing PCV system is a very common cause of oil leaks on these engines. The system is designed to relieve pressure from inside the engine, but when it gets blocked, that pressure builds up and forces oil out past seals and gaskets—especially the valve cover gasket. Saab even issued a Technical Service Bulletin (TSB 210-2418) for an updated PCV kit to solve this exact problem. If you replace the gasket without checking and servicing the PCV system, the new gasket will likely fail again quickly.
Choosing the Right Aftermarket Gasket Set
Not all aftermarket brands are created equal. For a critical seal like this, brand quality matters.
Tier 1: OEM Quality
These brands are known to be Original Equipment Manufacturers (OEM) for many European cars and are trusted by mechanics. They offer the best fit and longevity.
- Elring: A top-tier German brand. Elring gaskets are widely considered to be high-quality and are a reliable choice for your Saab.
- Victor Gaskets (Victor Reinz): Another excellent German OEM supplier. They are known for making flexible, well-fitting gaskets that install easily and seal properly.
Tier 2: Budget Option
These brands are more budget-focused. While they may be cheaper, the quality can be inconsistent.
- Professional Parts Sweden (PPS): This brand should be approached with caution. Many Saab owners and mechanics report poor quality, with parts that don't fit correctly or fail prematurely. It is generally recommended to avoid this brand for critical seals if your budget allows for a Tier 1 option.
Pro Tip: When replacing the gasket, be prepared to replace brittle plastic PCV hoses or check valves that connect to the valve cover. They often break upon removal due to age and heat.

Frequently Asked Questions
Is this a good DIY job for a beginner?
Yes, this is a great DIY job for those with basic tools. The process involves removing the ignition cassette, disconnecting a few hoses, and unbolting the valve cover. The key is to be clean, follow the bolt tightening sequence, and not over-tighten the bolts (the torque spec is 15 Nm or about 11 ft-lbs).
Do I need to use sealant on the new gasket?
The gasket itself is designed to seal without any additional sealant. However, many mechanics apply a very small amount of RTV silicone sealant at the sharp corners or half-moon areas to prevent leaks. Some also use a thin layer of grease or Vaseline to hold the gasket in place in the cover during installation, which makes the job much easier.
What tools do I need for the job?
You will need a basic socket set, a T30 Torx bit for the Direct Ignition Cassette, and a T40 Torx bit for the valve cover bolts. A torque wrench is highly recommended to tighten the bolts correctly. You will also need rags and brake cleaner to clean the surfaces.
What else should I replace at the same time?
Because a bad PCV system is the root cause of many leaks, it is highly recommended to install an updated PCV kit (Saab part #55 561 200) while you have everything apart. Also, inspect all vacuum lines and PCV hoses for cracks, as they become very brittle. It's also a perfect time to check or replace your spark plugs since you will have the ignition cassette removed.
Are there any recalls for this issue?
No, there have been no recalls issued by the NHTSA for a leaking valve cover gasket on the 1999-2004 Saab 9-5. Recalls for this vehicle range have focused on issues like the ignition module and airbags.
