⚙️ Key Features

• Standard size
• 88.5 g
• 82 applications across the V family
• Supersedes 3857671
• Engine group
• 8 used per assembly

🔌 Function

Seals the combustion pressure above the piston and controls the oil film on the bore, carrying heat from the piston out to the cylinder wall.

⚠️ Common Signs of Failure

• Blue smoke, especially on the overrun or under load
• Oil consumption climbing with no external leak
• Compression down and crankcase breathing heavily
• Bore glazed or the ring gaps opened right up
• A ring found broken or gummed solid in its groove

🛠️ Service Notes

• This is the standard size kit; the 0.030 inch oversize kit is 3857672, and its published weight of 22.7 grams is a quarter of this one, which cannot be right for the same set of rings — order by the size marking and not by weight
• Measure the bore and check each ring gap in its own bore before fitting
• It supersedes a higher number, 3857671, so an older list quoting that number is out of date
