Common failures during piston ring installation

1 、Misaligned assembly

When assembling piston rings, it is essential to ensure that they are installed correctly, aligned with piston grooves. Otherwise, aside from combustion chamber sealing being compromised, the constant movement of the rings may cause an irregular wear on the cylinder walls and an increase in engine oil consumption.

Consequence: with an irregular wear on cylinder walls and an increase in engine oil consumption, the engine will have its shelf life reduced and the owner will experience a significant increase in maintenance costs.

2 、Excessive or insufficient gap in the piston ring installation

The gap between piston rings and cylinder walls is also crucial to ensure combustion efficiency. If there is an excessive gap, sealing will be compromised, allowing gases to leak before complete explosion. On the other hand, an insufficient gap may result in excessive friction and overheating of these components.

Consequence: an inadequate gap may lead to a series of issues, from power loss and increase in fuel consumption to internal engine damage and ring deformation due to overheating.

3 、Damaged scrapers

scraper rings are very sensitive and may become deformed if the installer uses too much force during installation. This may cause lubrication issues, resulting in an excessive oil buildup in the chamber.

Consequence: oil buildup in the combustion chamber may lead to smoke emissions from the exhaust, increasing pollutant emission and compromising engine power and response.

4 、Inadequate tools

Using inadequate pliers and clamps or applying too much force may cause irreparable damages to the piston rings, which in the future may reflect in serious issues to the car.

Consequence: piston ring damages due to the inadequate use of tools may result in power loss, increase in the fuel consumption, and engine malfunctioning. In the worst-case scenario, they may end up damaging cylinders, which will require a much slower and more expensive engine repair.

5 、Mixing of lubricants during the piston ring installation

When installing piston rings, the Expert will also need to inject a small amount of lubricant oil in the set — the idea is to be sure that the first cycles of functioning will not cause component overheating. However, the inadequate choice or incorrect mixing of lubricants may lead to carbon deposits in cylinder walls and piston rings, compromising sealing and efficiency.

Consequence: damaged piston rings due to poor quality or inadequate mix of lubricants may result in excessive oil consumption, reduced engine performance, and increased emissions, as well as oil solidification and compression issues.

6 、Incorrect ring fitting

To close the list, we obviously have to highlight the ring fitting procedure, which is essential to allow rings to adequately fit the cylinder walls during engine rotation and promote an effective and long-lasting sealing. Otherwise, there may be a gap in compression and oil scraping deficiency, harming, among other things, chamber combustion.

Consequence: piston rings that were not fitted properly may result in compression leaks, excessive oil consumption, and early wear of engine components.
