⚠️ 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
