What does an oil filter housing do?
Most vehicles use an oil filter housing to secure the oil filter in place. The housing must be airtight and free of leaks so the oil is forced to pass through the filter before it reaches the engine. To make oil and filter changes easier, the housing is usually located on the side or top of the engine.
When the oil filter housing is cracked or impacted and engine oil starts to leak, the oil filter housing will have to be replaced. In this service, the mechanic assesses the oil filter housing and determines if it needs to be replaced.
How do you know if your oil filter housing is leaking?
Common signs that you may need to replace your oil filter housing include:
An oil change light or check engine light
Engine oil leaks on the ground underneath your vehicle
Low oil pressure or a low oil pressure warning light
A crack or deformation in the oil filter housing
The bottom line: Don’t ignore leaks, lights, and low oil pressure—you don’t want to know what happens if you ignore a faulty oil filter housing for too long!
How often should I replace the oil filter housing in my car?
The oil filter housing is intended to last your vehicle’s lifetime, so there’s no set expiry date. For that reason, it’s a good idea to get regular oil changes; that way, you can spot any problems before they become serious. Start checking for engine oil leaks when you look at the dipstick, too.
Can I replace an oil filter housing myself?
Oil changes are easy, but you might not be able to replace the oil filter housing yourself. Different car makes put the housing and gasket in different places; they might also have different ways of dismantling it. Given that you need a lift, a trained eye for detail, and three to four hours to change an oil filter housing, you might want to skip the DIY.
