## ⚠️ Common Signs of Failure

-   Oil weeping from the joint the washer seats against
-   Washer flattened or bedded into the mating face
-   Fastener losing clamp load and needing repeated retightening
-   Discoloration or hardening from nearby exhaust-side heat

## 🛠️ Service Notes

-   Check you are fitting the same type of washer that came out — plain, hardened, sealing and locking washers are not interchangeable, and the wrong one either fails to seal or fails to hold
-   Treat sealing washers on fuel, oil and coolant unions as single-use; they seal by deforming onto the faces, so a used one will not seal reliably a second time
-   Clean the seating faces and make sure the washer sits flat and square, fully under the head or nut, before tightening — a washer trapped on a chamfer or edge will crush unevenly
-   Tighten the fastener to the figure given in the workshop manual for your engine, and account for every washer on reassembly so none is left loose inside a housing or the engine bay
