Dorman Oil Filter Cap replacement, Aluminium direct-fit 917-016 — durable, OE-equivalent seal

The Dorman 917-016 Oil Filter Cap is a direct-fit aluminum replacement that restores a secure, leak-resistant seal for your engine’s oil filter housing.

If the original oil filter cap on your vehicle has cracked, stripped, or begun leaking, replacing it with a properly fitting cap is a quick way to regain reliable operation and simplify future oil changes. The Dorman 917-016 is manufactured from aluminum to resist high underhood temperatures and stress, and it’s engineered to match the OE dimensions so installation is straightforward. This product aims to deliver a durable, tested alternative when the factory part fails.

How does this cap match the original equipment fit?

The Dorman 917-016 is designed as a direct replacement, matching the original cap’s mounting points and sealing surface. That means the cap aligns with the housing without modification and maintains the original geometry for proper oil flow and sealing.

• Manufactured to OE-equivalent dimensions for correct alignment
• Sealing face engineered to mate with the existing housing and gasket
• No drilling, machining, or adapters required for installation

Will the aluminum construction resist cracking and leaking?

Aluminum offers improved thermal stability compared with some plastics, which helps the cap endure the repeated heat cycles under the hood. Dorman subjects replacement parts to quality testing to ensure they withstand typical engine temperatures and pressures without deforming.

• Aluminum body reduces risk of heat-related cracking
• Precision machining preserves threading and sealing surfaces
• Tested for fit and durability to help prevent early leaks

Is the cap easy to install during an oil change?

Installation is straightforward and typically requires only common hand tools, making it suitable for DIY oil changes. Because it’s a direct-fit part, you replace the old cap and torque to vehicle specs without additional parts or adapters.

• No specialty tools required—standard socket or wrench fits
• Drop-in replacement of the factory cap for fast service
• Reuses existing gasket or O-ring when compatible; replace gasket if worn

How can I confirm this cap fits my vehicle?

Vehicle fitment can vary by year, engine, and trim, so confirm compatibility before purchasing. Use make, model, year and trim information in the vehicle fitment tool or check the part number against the original cap to ensure a correct match.

• Enter precise vehicle details in the fitment/garage tool
• Compare OEM part number or original cap dimensions if available
• Contact the seller with VIN for exact fit verification if unsure
