## 🔌 Function

The cap plug closes the unused or service opening and seals the interface against leakage and contamination.

## ⚠️ Common Signs of Failure

-   Leakage or staining around the plug
-   Plug loosens or cannot retain pressure
-   Threads or locking lugs are damaged
-   Seal hardens or splits
-   Contamination enters through a missing plug

## 🛠️ Service Notes

-   Fit a new plug rather than refitting a used one — a plug that has been driven or screwed out will not seal reliably a second time
-   Clean the bore or threads out fully and check the sealing seat for corrosion pitting and damage; a pitted seat will keep weeping whatever plug is fitted
-   Fit the plug squarely and to the depth or tightness given in the workshop manual for your engine, using only the sealant or thread compound specified for that joint
-   Support the surrounding casting where you can and drive or tighten without distorting the plug, then pressure test or run the engine up and check the plug for weeping
