The oil filter housing holds the oil filter in place and provides a sealed connection to the engine’s oil system. In many modern vehicles, the oil cooler and sensors may also be integrated into the housing. Over time, the housing or its gaskets can crack, warp, or leak, leading to oil loss and reduced engine protection. Replacing a faulty oil filter housing ensures proper sealing and oil flow through the filter.

What is an oil filter housing replacement?

This service involves removing the damaged or leaking oil filter housing and installing a new unit. The gaskets and seals are also replaced to restore a proper seal and prevent future leaks.

Why do you need an oil filter housing replacement?

If the oil filter housing leaks, it can cause low oil levels and poor lubrication, leading to increased engine wear or even engine failure. Replacing it restores oil system integrity and prevents costly damage.
