How much bearing damage is too much

jsadamson said

I took every precaution I could think of and still messed up a single cam bearing. In hopes I don’t have to pull this motor, how much is too much? I have a single bearing that I messed up. The rest are perfect.

Can I smooth this out somehow?

You can change the bearing...in car...usually by removing the bearings in front of the damaged one. You'll have to pull the bearings you knock through out the valley window. You'll need a helper. You'll need the grab the bearing removed before it's completely loose so that it doesnt fall into the crank/oil pan.
Pretty much...that bearing is toast. Change it.


The reason for the wear should be found and remedied. It looks like it's A. Oil starved ...and B. Overheated. Check main bearing oil feeds alignment to blocks main saddle oil feed.
