How to Check the Ovality of Connecting Rods: A Comprehensive Guide

When it comes to connecting rods, ovality is a crucial factor to consider. If the connecting rod is too oval, it can lead to engine problems and decreased performance. However, checking the ovality of a connecting rod can be challenging, especially for beginners. In this guide, we will discuss everything you need to know about how to check the ovality of your connecting rods.

Firstly, it’s important to understand what ovality means in the context of connecting rods. Ovality refers to the shape of the rod between its ends, and if it is too oval, it can cause problems with the engine. To check for ovality, you will need a digital micrometer or dial indicator.

Start by clamping the connecting rod onto the crankshaft using the appropriate bolts and nuts. Then, use your micrometer to measure the distance between the two ends of the rod at several points along its length. You should take measurements at the top, middle, and bottom of the rod. If you find that the rod is too oval, it may be necessary to replace it with a new one.

It’s also worth noting that ovality can be caused by a variety of factors, including wear and tear on the engine, uneven compression, and incorrect camshaft timing. To prevent ovality from occurring in the first place, it’s important to regularly maintain your engine and keep an eye on any potential issues.

In conclusion, checking the ovality of your connecting rods is an essential part of maintaining your engine and ensuring optimal performance. By following these simple steps and taking the necessary precautions, you can avoid costly repairs and keep your car running smoothly for years to come.
