Don't look at cam bearings!?

The Hidden Peril of Neglecting Cam Bearings in Engine Maintenance



In the world of engine maintenance, cam bearings often remain in the shadows, yet their significance cannot be overstated. Despite common advice suggesting otherwise, overlooking cam bearings during engine inspections and rebuilds can have severe consequences on engine performance. This article explores the critical role of cam bearings, dispels myths, and emphasizes the importance of addressing them for optimal engine health.

Understanding the Myth: Why Cam Bearings Often Go Unnoticed

There exists a prevailing notion among mechanics and enthusiasts that cam bearings are 'set and forget' components. This misconception leads some to bypass inspection or replacement if no visible damage is present. However, this approach disregards the wear and tear these bearings undergo due to their vital role in supporting the camshaft and ensuring smooth operation.

Importance of Cam Bearings: Unveiling Their Vital Functions

Cam bearings act as a crucial support system for the camshaft, providing alignment and reducing friction. Their role in maintaining proper oil clearance is indispensable for effective lubrication, safeguarding against premature wear and tear of engine components.

Debunking the Myth: The Hidden Risks of Neglecting Cam Bearings

Neglecting cam bearings can lead to a domino effect of engine issues. Over time, wear in these bearings can cause misalignment, leading to increased friction, compromised lubrication, and potential damage to the camshaft lobes. This oversight could result in decreased engine performance and even catastrophic failure.


Prioritizing Cam Bearing Care for Engine Longevity

Cam bearings, often overlooked, are the unsung heroes of an engine's functionality. By dispelling myths, understanding their importance, and advocating for regular inspection and maintenance, enthusiasts can ensure an engine's robust performance over time.

Neglecting cam bearings is a risk not worth taking. Embrace a proactive approach to maintenance, safeguarding the core of your engine for sustained, reliable performance. Remember, a small investment in cam bearing care can yield significant dividends in the long run.


BUT...

In certain situations, it might be feasible to leave cam bearings untouched during an engine rebuild or maintenance if they appear to be in good condition upon inspection. However, this decision should be made cautiously, considering various factors:

While it's possible to avoid replacing cam bearings if they seem fine, there are inherent risks:

Ultimately, the decision to replace or not replace cam bearings should be based on a thorough assessment of their condition, considering the engine's history, intended use, and budget. While it's possible to leave them in place if they appear sound, it's a risk that could affect the engine's reliability and performance in the long run.
