What is an oil filter cap?
An oil filter cap is the plastic cover that seals the top of your engine's oil filter housing. It keeps oil contained and maintains proper oil pressure throughout the system. On 6.0L and 6.4L Powerstroke engines, it's a common wear item that cracks over time.
What does this oil filter and cap kit include?
This kit includes 1 oil filter cap and 1 oil filter. It's everything you need for a complete oil filter service on your 6.0L or 6.4L Powerstroke diesel engine. No additional parts are required for the replacement.

What part numbers does this replace?
The cap replaces EC781, 1840754C91, 3C3Z-6766-CA, RK31821, and 904-204. The filter replaces FL2016, 3C3Z-6731-AA, 1840752C91, PF1704, P7235, CH9549, 57311, P550528, LF16166, and ML1034.
What material is the oil filter cap made of?
The cap is made of high-grade heat-resistant plastic. It offers excellent oil resistance and corrosion resistance. The lightweight yet durable design reduces engine strain for long-lasting performance.
How often should I change the oil filter on a 6.0L Powerstroke?
Ford recommends changing the oil filter every 5,000 miles under normal driving conditions. For severe duty like towing or heavy hauling, change it every 3,000 miles. Regular oil filter changes protect your 6.0L Powerstroke engine from premature wear.
How do I know if my oil filter cap is bad?
Common signs include oil leaks around the filter housing, low oil pressure warnings, and a cracked or stripped cap. If you see oil dripping from the top of the oil filter housing on your 6.4L Powerstroke, the cap likely needs replacement. A loose or wobbly cap is also a clear warning sign.
Can I replace just the oil filter cap?
Yes, you can replace the cap separately if the filter is still good. However, it's most cost-effective to replace both at the same time during your regular oil change. This kit includes both the cap and filter for a complete service.
Is this an OEM Motorcraft part?
This kit is built to match OEM specifications for Motorcraft oil filter caps and filters. It fits and functions exactly like the factory parts on your 6.0L or 6.4L Powerstroke diesel. You get OEM quality at an aftermarket price.
How do I install the oil filter cap?
First, drain the oil and remove the old filter and cap. Lubricate the new O-ring with clean engine oil. Thread the new cap on by hand, then torque it to factory specification (typically 18–20 ft-lbs). Finally, install the new filter and refill with fresh oil.
What tools do I need to replace the oil filter cap?
You'll need a 32mm or 1 1/4" socket for the oil filter cap, a ratchet, and a drain pan. A torque wrench is recommended to avoid over-tightening. You may also need a filter wrench for the old oil filter.
Can I over-tighten the oil filter cap?
Yes, over-tightening is a common mistake that cracks plastic oil filter caps. Always use a torque wrench and follow the factory spec. On 6.0L and 6.4L Powerstroke engines, overtightening is the #1 cause of cap failure.
Why does the oil filter cap crack on 6.0L Powerstroke?
The factory plastic cap becomes brittle over time from heat cycles and oil exposure. Over-tightening during oil changes accelerates cracking. The 6.0L Powerstroke runs high oil pressure, which puts extra stress on the cap housing.
Will a leaking oil filter cap cause low oil pressure?
Yes, a cracked or loose oil filter cap can cause oil leaks that lead to low oil pressure. This is especially dangerous on 6.0L and 6.4L Powerstroke diesels that rely on high oil pressure for fuel injection and turbo operation. Always replace a leaking cap immediately.
Does this come with the O-ring?
Yes, the oil filter cap includes the necessary O-ring seal for proper installation. The oil filter also comes with its own sealing gasket. Everything needed for a leak-free install is included in the kit.
How long does it take to replace the oil filter and cap?
Replacing the oil filter and cap takes about 30–45 minutes as part of a standard oil change. If you're only replacing the cap, it can be done in 15–20 minutes. No special tools are required beyond basic sockets and a drain pan.
Can I drive with a cracked oil filter cap?
We don't recommend driving with a cracked oil filter cap. A leaking cap can cause rapid oil loss and engine damage on your 6.0L Powerstroke. If you notice a leak, replace the cap as soon as possible to avoid costly engine failure.
Is this the same as Motorcraft FL2016?
Yes, the oil filter in this kit is equivalent to Motorcraft FL2016 (3C3Z-6731-AA). It meets the same filtration standards and fits all the same 6.0L and 6.4L Powerstroke applications. It's a direct cross-reference replacement.
