How Much does an Oil Filter Housing Replacement Cost?
Your engine oil is kept clean by passing through your oil filter as it circulates through your engine.
Between your engine and the oil filter is a mount known as the oil filter housing.
As you drive your car normally, the oil filter housing itself should never need to be replaced.
However, you might find that it develops a leak from the gaskets or it may develop a crack in the oil filter housing itself, which will require replacement.
The average cost to replace the oil filter housing is $171 to $655 depending on the make and model, and a few cars may be higher than that.
Even though the oil filter housing itself may never fail, the oil filter housing gasket is a common point of failure.
Oil Filter Housing Replacement
What is an Oil Filter Housing?
An oil filter housing is on virtually every engine manufactured. It’s the part where an external oil filter screws onto, or an internal oil filter is secured into.
The oil filter housing on most cars is located in a spot that’s easily accessible for oil and filter changes, typically either on the top of the engine near the front or on the side of the engine with the filter accessible from the bottom.
The oil filter housing is nearly always cast out of aluminum although some older models may be made from cast iron.
A gasket is between the engine assembly and the oil filter housing.
If the oil filter housing is impacted or otherwise cracked, or if the mounting surface is warped, engine oil will leak and the oil filter housing will need to be replaced.
Symptoms You Need Oil Filter Housing Replacement
- An engine oil leak is detected
- There’s a crack evident in the oil filter housing
How is Oil Filter Housing Replacement Performed?
- The engine oil leak is inspected and the oil filter housing diagnosed as the cause
- The technician creates access to the oil filter housing. It may require lifting the car on a hoist or removal of other components to allow room to remove the oil filter housing
- The engine oil is drained
- The oil filter housing is unbolted from its mounting location and a new one fitted in place
- The technician refits removed parts and lowers the car
- The engine oil is filled and the engine is run to verify the leak is repaired
Tips to Remember
- In most instances, the oil filter gasket is the cause of the engine oil leak, not the oil filter housing itself.
- The engine oil and filter should be changed at the same time as the oil filter housing or gasket.
How Important is Oil Filter Housing Replacement?
When the oil filter housing is leaking oil, it’s easy to lose confidence in your car’s reliability.
Replacing the oil filter housing when it’s needed will restore your faith in your car.
As well, running your engine for a long time with a leaking oil filter housing can result in extensive engine damage.
While it’s leaking, close attention should be paid to the engine oil level to prevent an overheated or seized engine.
