⚙️ Key Features

• 0.002 kg
• 28 applications across four engine series
• Lubricating and Oil System blanking plug

🔌 Function

Blanks off a drilling or port in the oil circuit so pressure is contained and the gallery is sealed.

⚠️ Common Signs of Failure

• Oil weeping or dripping from the plug boss
• Plug thread or drive recess damaged on removal
• Plug backed out slightly, with an oil track below it
• Oil pressure lower than expected with no other cause found

🛠️ Service Notes

• Renew the seal ring or washer with the plug rather than reusing the old one
• Tighten to the manual figure — an overtightened plug will split its boss on a legacy casting
