## 🔌 Function

Seals combustion pressure above the piston, controls oil on the cylinder wall and transfers piston heat into the liner.

## ⚠️ Common Signs of Failure

-   Excessive crankcase blow-by
-   Blue exhaust smoke and high oil consumption
-   Reduced power or poor cylinder balance
-   Broken, stuck or heavily worn piston rings

## 🛠️ Service Notes

-   Check the end gap of each ring in the bore it will run in and compare it with the figure in the workshop manual for your engine; a worn or rebored cylinder changes it
-   Fit the rings the right way up — where a face is marked or the section is stepped, that face goes towards the piston crown, and an oil control ring's expander must be fitted without overlapping its own ends
-   Use a ring expander rather than levering rings on with a screwdriver, and open them only as far as they need to go; cast rings snap and the groove edges nick easily
-   Stagger the ring gaps round the piston as the manual for your engine directs, so that no two gaps line up
-   Oil the rings, bore and compressor lightly, enter the bore with a ring compressor, and never force the piston in — if it resists, back it out and find out why
