Possible causes for the damage Excessive clearances in the connecting rod bearings or a worn-out connecting rod bearing, particularly in conjunction with over-revving when driving downhill. The gap dimension (the minimum distance between the piston crown and the cylinder head) was too small at TDC of the piston.

What can damage piston rings?
- Mixed friction – metal contact occurs between the piston ring and cylinder wall. After damage due to dirt, damage and wear caused by fuel flooding is the second most common cause of damage on piston rings. ... - Oil film with sufficient thickness – no metal contact. ... - New and worn oil control ring.
What causes piston rings to wear out?
Bad fuel or cylinder oil quality, bad combustion process, wrong fuel timing, worn liner etc. are the normal cause of piston rings worn out. The most common indication or sign of a worn ring is gas passing into the crankcase or under piston area known as blowby.
What would cause piston rings to go bad?
The two main causes of wearing out of piston rings and most engine parts are dirt contamination. Dirt enters the engine through faulty air filters. Similarly, dirt can make its way to the engine through the oil circuit by contaminated oil. Therefore here are the easiest ways to increase your piston rings lifespan.
Piston Rings & Blowby - Explained
What causes piston rings to fail?
Bad fuel or cylinder oil quality, bad combustion process, wrong fuel timing, worn liner etc. are the normal cause of piston rings worn out. The most common indication or sign of a worn ring is gas passing into the crankcase or under piston area known as blowby.
What happens if piston rings break?
Common Symptoms of Damaged Piston Rings White or gray exhaust smoke. Excessive oil consumption. Low power for acceleration. Overall loss of power or poor performance.
How do piston rings wear out?
During engine operation, combustion faults often result in an accumulation and condensation of fuel on the cylinder wall. In this case, the oil film is thinned or washed off. The resulting mixed friction causes the piston rings to wear completely within a few thousand kilometres.
Piston Ring Failure Analysis
How do I know if my piston rings are worn?
When drivers notice excessive oil consumption, white or gray exhaust smoke, poor acceleration, and/or overall loss of power or poor engine performance, they may be seeing signs of worn piston rings.
What causes premature piston ring wear?
The most common reason for premature or rapid piston ring wear is an overheated combustion environment. It is never recommended to leave the engine overheating unchecked.
Piston Rings 101: Break-In Procedure - With Lake Speed Jr.
What happens if you drive with bad piston rings?
When piston rings suffer wear or get damaged, your engine will lose its power because there is less compression taking place. This means when you put your foot on the gas pedal to accelerate, the vehicle will take a long time to speed up.
How do piston rings not wear out?
Bad gas (detonation and pinging), dirty air and fuel, and contaminated oil all reduce the life of piston rings. Maintaining the filters on your engine and regular oil changes make a big difference in how long the rings last. Once the rings have worn down, their ability to seal the combustion gases will become apparent.
