⚠️ Common Signs of Failure

• Diesel weeping at the joint the screw clamps
• Hard starting or hunting from air drawn in at a loosened joint
• Screw found loose or backed out
• Head recess rounded out so a socket will not grip
• Thread pulled in the alloy housing

🛠️ Service Notes

• Supersedes flange screw 20850155, so the head form has changed - check the clamped height against parts list for your engine if you are matching an old screw
• Easy to over-torque into an alloy housing at this size - check the female thread before refitting
