Cam bearings

Icetech said
Always wonder why cam bearings lose chunks like that.. mine had a few small chunks missing.. i would like to tell you that i changed them... but....

Acid in the oil, they break down over time. Sitting long periods of time (years) is hard on them too.

Just a guess > valve spring pressure pushing on them 24/7 when sitting for long periods, without being turned over eventually the oil film goes away...
