## 🔌 Function

Seals the combustion chamber during compression and firing, then opens to release the burnt gas into the exhaust port.

## ⚠️ Common Signs of Failure

-   Loss of compression and hard starting on one cylinder
-   Rough idle with a puffing note back through the exhaust

-   Tulip cracked or the head distorted by overheating

## 🛠️ Service Notes
