## ⚙️ Key Features

-   Genuine Volvo Penta lubrication-system plug
-   Closes an unused oil-pan or guide-tube port

-   Used with alternate dipstick/guide-tube configurations
-   Match oil-pan casting and engine serial number

## 🔌 Function

Seals an unused oil-level guide-tube opening so engine oil remains contained and contaminants cannot enter.

## ⚠️ Common Signs of Failure

-   Oil or fluid leakage at the sealing lip
-   Hardening, cracking or lip damage
-   Grooving or corrosion on the mating shaft surface
-   Seal displacement or incorrect installation depth
-   Contamination or repeated leakage after replacement

## 🛠️ 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
