Saturn Outlook Engine Valve Cover Gasket Sets: A 2007-2010 Owner's Guide
An oil leak on your Saturn Outlook's 3.6L V6 often points to a failed valve cover gasket; here is what you need to know.
- A burning oil smell is the most common sign of a failing valve cover gasket on your Outlook.
- Replacement is a difficult, labor-intensive job (4-5 hours) because the rear gasket is under the intake manifold.
- Due to the high labor cost, using a high-quality gasket set (like Victor Reinz) is strongly recommended over budget options to avoid repeat repairs.
- Always replace gaskets for both banks (front and rear) at the same time, including all spark plug tube seals and grommets in the kit.
Is Your Outlook Leaking Oil?
The valve cover gaskets on the 3.6L V6 engine in the 2007-2010 Saturn Outlook are made of rubber. Over time, constant heat from the engine causes them to harden, crack, and shrink. This allows engine oil to seep out. Because of the high labor cost involved in a replacement, especially for the rear gasket, it is critical to choose a quality part to avoid doing the job twice.
Symptoms of a Failing Valve Cover Gasket
When these gaskets fail, they leave clear signs. The most common is a burning oil smell, which happens when leaking oil drips onto the hot exhaust manifold. You might also see oily, wet-looking areas on the engine itself, particularly around the top edges. If the leak is bad enough, you may see oil spots on the ground where you park. A slow leak can cause your engine oil level to drop over time, so it's important to check your dipstick regularly. In some cases, oil can leak into the spark plug tubes, causing the engine to misfire and run poorly.
A Note on PCV System Issues
General Motors issued a Technical Service Bulletin (TSB) for a Positive Crankcase Ventilation (PCV) system issue on these engines. The fix often involves removing the valve covers and replacing the gaskets, so a leaking gasket may be related to this known issue.
Choosing the Right Aftermarket Gasket Set
Since replacing these gaskets is a labor-intensive job, the quality of the replacement part matters a lot. You don't want to pay a mechanic (or spend a whole weekend) to do this job again in a year because of a cheap gasket.
- Premium Aftermarket (e.g., Victor Gaskets / Victor Reinz): Brands like Victor Reinz are known for making parts that meet or exceed original equipment (OE) quality. They are often made from high-quality materials designed for a precise fit and long-lasting seal. For a difficult job like this, spending a little more on a premium gasket is a smart investment for peace of mind.
- Standard/Economy Aftermarket (e.g., Apex): Brands like Apex offer a more budget-friendly option. While they can get the job done, the materials and fit might not be as robust as premium brands. Given the high cost of labor to fix a potential re-leak, a standard gasket is a riskier choice for this specific repair on the Outlook.
Pro Tip: Replace in Sets
Your V6 engine has two valve cover gaskets (front and rear). If one is leaking, the other is the same age and has been exposed to the same conditions. It is highly recommended to replace both gasket sets at the same time, along with all included spark plug tube seals and bolt grommets, to prevent having to do the job again soon.
Cost to Replace Saturn Outlook Valve Cover Gaskets
The cost is mostly labor due to the difficult-to-access rear valve cover. The intake manifold often needs to be removed to reach it.
| Part Type | Estimated Part Cost | Estimated Labor Cost |
|---|---|---|
| New Aftermarket Set | $44 - $99 | $390 - $570 |
| New OEM Set (ACDelco) | $96 - $114 | $390 - $570 |
Frequently Asked Questions
Is there a recall for the valve cover gaskets on my Saturn Outlook?
No. There have been no safety recalls issued by the NHTSA for failing valve cover gaskets on the 2007-2010 Saturn Outlook.
Why is the rear gasket so much harder to replace than the front?
The 3.6L V6 engine is mounted sideways (transversely) in the engine bay. The front valve cover is easily accessible, but the rear cover is tucked back against the firewall, underneath the large intake manifold. This manifold must be removed to gain access, which adds significant time and complexity to the job.
Can I just tighten the bolts on the valve cover to stop the leak?
This is not recommended and rarely works. The leak is caused by a hardened and shrunken gasket, not loose bolts. The bolts are torqued to a specific, low specification (around 89 lb-in). Over-tightening them can crack the valve cover or strip the threads, leading to a much more expensive repair.
What's the difference between a valve cover and an engine cover?
The engine cover is the large plastic piece you see when you open the hood, often with a logo on it. It is purely for looks and sound-dampening. The valve covers are the functional metal or composite parts underneath that decorative cover, which are sealed by the valve cover gaskets.
