Uh-Oh! Cam Bearing Time!!!

Here is a picture of a cam bearing from my 340. Its the original bearing installed by chrysler. This flaking or debonding of bearing material can happen with age, or lack of maintenance. On this particular engine the cam bearing oil holes were not lined up well at all. The cam journals were fine on the cam.

That's what the cam bearings in my street Hemi looked like when I rebuilt it. Replaced the bearings, cam was OK and I re-used it. In fact, it still has the same cam in it almost 30 years later.
