A Ford Probe Owner's Guide to Engine Valve Cover Gasket Sets (1990-1997)
Stop oil leaks and burning smells by choosing the right replacement valve cover gasket set for your Probe's engine.
- For the 2.5L V6, the rear gasket is much harder to replace than the front, requiring removal of the intake manifold.
- Always replace the spark plug tube seals and bolt grommets that come in the kit to prevent future leaks.
- Thoroughly clean all mating surfaces before installing the new gasket, and use a plastic scraper to avoid damaging the aluminum head.
- Do not over-tighten the valve cover bolts; use a torque wrench set to the factory specification (typically 43-78 inch-pounds).
Is Your Ford Probe Leaking Oil? Check the Valve Cover Gaskets
A common issue on aging 1990-1997 Ford Probes is a leaking valve cover gasket. Over time, the original rubber or cork gaskets become hard and brittle from engine heat, causing them to crack and lose their seal. This allows oil to seep out, leading to several noticeable problems. Addressing this leak is important to prevent oil loss, potential engine damage, and fire hazards.
Symptoms of a Failing Valve Cover Gasket
If your valve cover gasket is failing, you'll likely notice one or more of these signs:
- Burning Oil Smell: This is the most common symptom. Oil drips from the valve cover onto the hot exhaust manifold, where it burns off and creates a distinct, unpleasant smell that can enter the car's cabin.
- Visible Oil Leaks: You may see oil residue and grime caked onto the valve cover and the side of the cylinder head. On the V6 engine, the rear gasket is a frequent leaker and can drip oil onto the exhaust crossover pipe.
- Oil in Spark Plug Wells: When you pull the spark plug wires, you might find oil pooled in the spark plug tubes. This is caused by failed spark plug tube seals, which are almost always included in a valve cover gasket set. This can lead to engine misfires and a check engine light.
- Low Engine Oil: A significant leak will cause your engine oil level to drop over time, potentially triggering the oil light on your dashboard.
V6 Owners: The Rear Gasket is the Hard Part
On the 2.5L V6 engine, replacing the front valve cover gasket is a relatively simple job. However, accessing the rear valve cover requires removing the upper intake manifold, which makes the job significantly more complex and time-consuming. 🎬 Watch this guide on removing the intake and rear cover. If you are paying a mechanic, expect labor costs to be much higher for the rear gasket. Most owners replace both at the same time to avoid doing the job twice.
Choosing the Right Aftermarket Gasket Set
For a vehicle like the 1990-1997 Ford Probe, aftermarket gaskets offer excellent value and quality. Some forum users even suggest that modern aftermarket gaskets can be an improvement over the original factory parts. The key is to choose a reputable brand. Your gasket set should always include the main valve cover gasket(s), spark plug tube seals, and new bolt grommets.
Brand Quality Tiers
- Premium Choice (Victor Reinz, Beck Arnley): Victor Reinz is a well-respected OEM (Original Equipment Manufacturer) supplier for many European brands, and their quality is consistently high. Beck Arnley often repackages OEM parts (in this case, likely from Mazda, as the Probe's engines are Mazda-designed), making them a reliable choice. These brands are a great option if you want maximum longevity, especially for the difficult-to-access rear gasket on the V6.
- Quality Mid-Range (Fel-Pro): Fel-Pro is a very popular and trusted name in the aftermarket gasket world. They are known for designing gaskets specifically for the repair environment, often with features that help seal imperfect surfaces. They are a solid, reliable choice for any Probe owner. 🎬 See a full walkthrough of the V6 gasket replacement process.
- Standard/Economy (Apex): Apex is a more budget-friendly option. While some users report success, others have experienced shorter lifespans compared to premium brands. Some packaging suggests a relationship with Fel-Pro, but quality can be inconsistent. This brand might be suitable for the easily accessible front gasket on a V6 or for the 4-cylinder engine if budget is the primary concern.
Pro Tip: Proper Preparation is Key
The success of your gasket replacement depends heavily on preparation. Thoroughly clean the sealing surfaces on both the cylinder head and the valve cover. Use a plastic scraper to avoid gouging the aluminum head. Also, be sure to apply a small dab of RTV sealant at any sharp corners or seams, such as where the timing cover meets the head, as specified by the service manual.

Frequently Asked Questions
Do I need to use RTV sealant with the gasket?
Yes, but only in specific spots. You should apply a small amount of high-temp RTV silicone sealant to the sharp corners where the cylinder head meets the timing belt cover or distributor housing. Do not coat the entire gasket in sealant. The new gasket is designed to be installed dry in the valve cover's groove.
Should I replace the spark plug tube seals and bolt grommets?
Absolutely. A quality gasket set will include these parts. The tube seals prevent oil from fouling your spark plugs, and the grommets ensure the valve cover bolts apply even pressure without cracking the cover. Old, hardened grommets are a common source of leaks.
What are the torque specs for the valve cover bolts?
The torque specs are very low, typically around 43-78 inch-pounds. It is critical not to over-tighten the bolts, as this can warp or crack the valve cover and cause the new gasket to leak. Always use an inch-pound torque wrench and tighten the bolts in the sequence recommended by the service manual.
Is replacing the rear valve cover gasket on the V6 a good DIY job?
It can be, but it is an advanced project. The job requires removing the entire upper intake manifold, which involves disconnecting numerous hoses, electrical connectors, and fuel lines. If you are not experienced or do not have a good set of tools and a service manual, it may be best to leave this job to a professional.
