🔌 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
