## ⚠️ Common Signs of Failure

-   Low cylinder compression
-   Excessive crankcase blow-by
-   Oil consumption or liner scoring
-   Major gasket leakage

## 🛠️ Service Notes

-   Lay the kit out against the assembly before you start, so you can confirm it matches the unit you are working on and that nothing is missing
-   Use everything the kit supplies — the point of an overhaul kit is that every wearing seal and gasket is renewed at once, and leaving one original seal in place is the usual cause of a repeat failure
-   Work clean: these kits go into fuel, oil, cooling and hydraulic units where a single piece of grit will ruin the job, so clean the outside of the unit and cap open ports before opening it up
-   Inspect what the kit does not replace — bores, sealing faces, shafts and threads — because a kit cannot make up for a worn or scored housing
-   Follow the assembly sequence and the tightening figures in the workshop manual for your engine, and note that some kits include fasteners intended for single use
