## ⚠️ Common Signs of Failure

-   Oil seeping or dripping from the front of the engine at the cover joint
-   Oil misting onto the belt, pulleys or engine front
-   Oil level falling with no other visible leak
-   Cover face corroded, pitted or the gasket land damaged
-   Cracked cover or a distorted, warped sealing face found on removal

## 🛠️ Service Notes

-   Renew the mating gasket 21193274 whenever the cover is removed, as the joint will not reseal on the old one
-   This cover replaces 21192344 and 3583714, one of which was listed earlier as a cap, so check the casting profile against the engine before fitting
-   Check the front oil seal condition while the cover is off, as it is far easier to renew at that point
