Ford Taurus PCV Valve Grommets
Ford Taurus Pcv valve grommets
Starting at $3.95, AutoBuffy stocks 4 PCV valve grommets from Standard Ignition for the Ford Taurus. The grommet seals the PCV valve into the valve cover, isolating crankcase vapors from open air. When it cracks or hardens, unmetered air enters the engine, causing rough idle, oil leaks, and failed emissions tests.
Signs your Ford Taurus needs a new PCV valve grommet
- Rough or erratic idle that worsens at operating temperature — vacuum leak from a cracked grommet disrupts the air-fuel ratio
- Oil film or residue around the PCV valve port on the valve cover, indicating the grommet is no longer sealing
- Check Engine light with a lean condition or mass airflow code caused by unmetered air bypassing the intake system
- Increased oil consumption or bluish exhaust smoke if crankcase pressure is no longer being properly managed
- Hissing sound near the valve cover at idle — audible vacuum leak from a shrunken or split grommet
- Failed emissions test due to improper crankcase ventilation allowing hydrocarbon levels to rise
Which PCV valve grommet should you buy for your Ford Taurus?
The main decisions are material quality and fitment precision. Factory-style grommets must seal against both the valve cover bore and the PCV valve body, so inner and outer diameter accuracy matters more than it might seem. Some vehicles also use a grommet integrated with a collar or baffle, so confirming the exact configuration before ordering saves a return trip.
OE-spec rubber grommet
Best for
Owners who want a straightforward like-for-like replacement
What you get
Correct durometer rubber matched to factory dimensions; resists engine oil and heat within normal operating ranges
Reinforced silicone grommet
Best for
High-mileage engines or vehicles in extreme climates
What you get
Higher heat and oil resistance than standard rubber; less prone to hardening or cracking over time
Grommet + PCV valve kit
Best for
Vehicles where the valve and grommet are worn simultaneously
What you get
Both components in one purchase; ensures the new grommet seats properly with a new valve of the correct stem diameter
OEM-brand grommet
Best for
Owners who want to match factory part specifications exactly
What you get
Made by or to the spec of the original supplier; best assurance of dimensional accuracy for tight valve cover tolerances

Replacing a PCV valve grommet on a Ford Taurus
Easy⏱ 15–45 minutesFlathead screwdriver or trim tool (to pry out old grommet)Needle-nose pliers (to remove PCV valve hose clamp if present)Clean shop ragsFlashlight or work light
Disconnect the hose from the PCV valve, twist or pull the valve free, then pry the old grommet out of the valve cover bore using a flathead screwdriver — take care not to gouge the bore. Press the new grommet firmly into the bore by hand until it seats flush, reinstall the PCV valve, and reconnect the hose. Start the engine and check around the grommet for any sign of vacuum leak or oil weeping before closing the hood.
Frequently asked questions
How much does it cost to replace PCV valve grommets on a Ford Taurus?
The grommet itself starts at $3.95 at AutoBuffy. DIY total cost is typically just the part plus a few minutes of labor. A shop may bundle it with a PCV valve replacement and charge a modest labor fee, but because access is usually straightforward, most owners handle it without professional help.
Can I drive my Ford Taurus with a bad PCV valve grommet?
Short distances are unlikely to cause immediate damage, but you should replace it promptly. A failed grommet creates a vacuum leak that leans out the air-fuel mixture, stresses the oxygen sensors, and can allow oil to seep onto hot engine components. Prolonged driving worsens fuel economy and risks further engine management issues.
How do I know if the grommet or the PCV valve itself is the problem on my Ford Taurus?
Inspect the grommet first — look for cracking, shrinkage, or deformation around the valve cover bore. If the grommet looks intact, remove the PCV valve and shake it; a functioning valve rattles freely. A stuck or oil-clogged valve alongside a hardened grommet is common, so replacing both at the same time is usually the practical choice.
How often should the PCV valve grommet be replaced on a Ford Taurus?
There is no fixed mileage interval. Rubber grommets typically last many years but degrade faster in high-heat engine bays or if the oil change schedule has been neglected. Most technicians recommend inspecting it whenever the PCV valve is serviced or during a valve cover gasket job, since access is already open at that point.
Will a leaking PCV valve grommet cause an oil leak on my Ford Taurus?
Yes. When the grommet fails to seal the PCV valve against the valve cover, crankcase pressure can push oil past the gap. This typically appears as an oily residue or wet spot around the PCV valve port. It is often mistaken for a valve cover gasket leak until the grommet is inspected directly.
Is replacing a PCV valve grommet on a Ford Taurus a DIY job?
For most vehicles, yes. The grommet simply pulls out and presses back in once the PCV valve is removed. No special tools are required beyond basic hand tools. The job is accessible to a careful first-time DIYer in under 30 minutes on most engines, provided the valve cover area is reasonably easy to reach.
