Where are the bearings located on the camshaft?
Camshaft bearings allow the camshaft to move freely. They are located between the camshaft and the engine block. They fail less often than rod or main bearings, but nevertheless should be replaced when overhauling an engine.
What’s the minimum clearance for a cam bearing?
Minimum clearance should be 0.002˝ for stock engines and 0.003-0.004˝ for high-performance engines. If cam fit is too tight, bearing material can be removed by reaming.
What causes low oil pressure when camshaft bearings are worn?
Metal flakes or shavings found in the engine oil are a potential sign that the camshaft bearings are worn. They may also cause low oil pressure once the engine warms up or make chirping noises. This can be caused by lack of lubrication or just normal wear and tear.
What kind of material is used in cam bearings?
In previous years, the vast majority of cam bearings were manufactured with a babbitt lining. Babbitt is a soft, slippery material composed primarily of lead and tin. This soft material does an excellent job of being able to withstand particle contamination and less-than-ideal lubrication on initial engine startup.

Is it required to change cam bearing every Cam change?
And yes the the cam bearings are the first things to get oil from the pump. But if they are too tight or too loose it will have a major effect on oil pressure down the line to more critically loaded parts of your engine such as the main bearings. Last edited by TWR2003; 06-20-2008 at 02:12 PM .
