## ⚠️ Common Signs of Failure

-   Oil or water leakage around the plug
-   Corrosion seizure
-   Incorrect plug protrusion interfering with internal components
-   Water contamination from failed seal

## 🛠️ Service Notes

-   Clean the threads and the seating face before fitting, and make sure the opening itself is clear of old sealant, swarf and corrosion
-   Renew the sealing washer or O-ring where one is fitted rather than reusing a flattened one, and only use thread sealant where the workshop manual for your engine calls for it
-   Tighten to the figure given in the workshop manual for your engine — plugs in aluminium and other soft castings strip easily, and a plug pulled up hard to cure a leak usually distorts the seat and makes it worse
-   Where the plug closes an oil, fuel or coolant passage, run the engine up to temperature afterwards and check the joint under pressure before signing the job off
-   Keep removed plugs paired with the holes they came out of during a strip-down — plugs of very similar appearance often differ in thread, reach or sealing type
