-   Engine group
-   0.816 kg
-   Listed for 9 applications

## 🔌 Function

Converts combustion pressure into thrust on the connecting rod and carries the rings that seal the bore.

## ⚠️ Common Signs of Failure

-   Blue smoke and rising oil consumption
-   Piston slap, a hollow knock when cold that quietens as the engine warms
-   Scuffed or scored skirt, or a broken ring land
-   Erosion or heavy carbon damage on the crown
-   Compression down on one cylinder

## 🛠️ Service Notes

-   Valve tappet 3850385 covers the same 9 applications, so both belong to the same engine family
-   Measure the bore and check ring gap before assembly, since a new piston is no use in a worn bore
-   Fit new rings and gudgeon retainers rather than reusing the old ones
