When I tore down my 340 I noticed the cam bearings were not centered in their bores. Didn't think much about it, just thought whoever built the motor the last time was sloppy. However, when I went to install the new bearings I noticed the oiling holes in the black on #2,3 and 4 aren't nearly centered.
So I think my possible answers are:
Leave them slightly hanging out like the last builder did.
Drill the oiling holes in the bearings larger before installation and dress them with scotchbrite.
Saw a post on FABO to run a long drill down the oiling passage and drill them after they are installed then clean them up.
If I install them in the correct spot it seems the majority of the oil passage would be covered. Thoughts?
