-   Listed for 8 TAD-series applications

## 🔌 Function

Blanks off an unused port or opening in the engine housing or harness support, keeping dirt and moisture out.

## ⚠️ Common Signs of Failure

-   Plug missing, leaving an open port collecting dirt or water
-   Plug pushed out or sitting loose in its bore
-   Body cracked or split, usually at the flange
-   Corrosion or debris found in the port the plug should have protected

## 🛠️ 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
