The oil filter housing is a crucial component of your vehicle’s lubrication system. It secures the oil filter in place and ensures proper filtration of engine oil, preventing contaminants from damaging engine components. Over time, this housing can develop leaks or cracks, requiring oil filter housing replacement. Understanding how it works, common failure symptoms, and replacement costs can help you maintain your vehicle and prevent costly repairs.
What Is an Oil Filter Housing?
An oil filter housing is a metal or plastic component that holds the oil filter and connects it to the engine. It typically includes:
- A mounting point for the oil filter
- Oil passages that direct oil flow through the filter
- Seals and gaskets to prevent leaks
Some vehicles use a cartridge-style oil filter housing, while others use a spin-on filter system. The type of housing depends on the vehicle manufacturer and design.
How Does an Oil Filter Housing Work?
The oil filter housing plays a vital role in the engine oil filtration system:
- Oil is drawn from the oil pan – The oil pump sends oil through the engine’s lubrication system.
- Oil flows into the filter housing – The housing directs the oil into the oil filter, where contaminants are trapped.
- Filtered oil returns to the engine – Once cleaned, the oil continues circulating to lubricate engine components.
Types of Oil Filter Housings and Their Use Cases
Oil filter housings vary based on vehicle design and engine type. Here are the most common types:
1. Spin-On Oil Filter Housing
- Common in older vehicles and some modern models.
- The filter screws directly onto the housing.
- Pros: Easy to replace, inexpensive.
- Cons: Can be prone to leaks if not installed properly.
2. Cartridge Oil Filter Housing
- Found in many newer vehicles.
- Uses a replaceable filter element inside the housing.
- Pros: Environmentally friendly, less waste.
- Cons: More complex installation, requires special tools.
3. Remote-Mounted Oil Filter Housing
- Used in performance or off-road vehicles.
- Allows relocation of the oil filter for easier access.
- Pros: Better cooling, convenient maintenance.
- Cons: Additional hoses and fittings required.
Common Causes of Oil Filter Housing Failure
Over time, the oil filter housing can develop issues that require replacement. Common causes include:
- Cracked or Damaged Housing – Heat cycles and vibrations can cause plastic housings to crack.
- Leaking Gaskets or Seals – The seals around the housing can degrade, leading to oil leaks.
- Improper Installation – Overtightening or misalignment can cause leaks or damage.
- Contaminant Buildup – Dirty oil can clog passages, reducing oil flow.
Signs You Need an Oil Filter Housing Replacement
If your oil filter housing is failing, you may notice these symptoms:
- Oil Leaks – Visible oil dripping from the engine bay.
- Low Oil Pressure Warning – Leaks or blockages can reduce oil pressure.
- Burning Oil Smell – Leaking oil can burn on the engine surface.
- Overheating Engine – Poor lubrication can lead to higher engine temperatures.
Engine Oil Filter Housing Replacement Cost
The cost of engine oil filter housing replacement varies based on vehicle make and model:
- Parts Cost: $50 - $300 (OEM or aftermarket replacement)
- Labor Cost: $150 - $500 (depending on accessibility and mechanic rates)
- Total Replacement Cost: $200 - $800
DIY Guide: How to Replace an Oil Filter Housing
Replacing an oil filter housing can be a DIY-friendly job with the right tools and knowledge.
Tools and Supplies Needed:
- New oil filter housing (OEM or aftermarket)
- Socket wrench set
- Torque wrench
- Oil filter removal tool
- Drain pan
- New engine oil and oil filter
- Gasket or seal kit
- Safety gloves and shop towels
Steps to Replace an Oil Filter Housing:
- Ensure the Engine Is Cool – Never work on a hot engine.
- Drain the Engine Oil – Place a drain pan under the oil pan and remove the drain plug.
- Locate the Oil Filter Housing – Typically found near the engine block.
- Remove the Oil Filter and Housing Bolts – Use a socket wrench to detach the housing.
- Clean the Mounting Surface – Remove any old gasket residue.
- Install the New Oil Filter Housing – Align it properly and tighten the bolts to the recommended torque.
- Replace the Oil Filter – Install a new oil filter and apply fresh oil.
- Refill the Engine with Oil – Check for leaks and start the engine.
- Monitor for Leaks and Test Drive – Ensure the engine runs smoothly without leaks.
Additional Parts You Might Need
When replacing an oil filter housing, consider checking or replacing these related components:
- Oil Filter – Always replace the filter with the housing.
- Oil Pressure Sensor – If leaking, it should be replaced.
- Gaskets and Seals – Prevent future leaks by installing fresh seals.
- New Engine Oil – Necessary after any oil system repair.
Conclusion
The oil filter housing is a vital part of your engine’s lubrication system, ensuring proper oil filtration and preventing contaminants from damaging internal components. If you notice oil leaks, low oil pressure, or a burning oil smell, it may be time for an oil filter housing replacement. Whether you choose a DIY approach or professional service, maintaining a properly functioning engine oil filter housing can help extend the life of your engine and keep your vehicle running smoothly.
