Slant 6 timing chain lubrication?

Dne007 said

Just practicing on an old main bearing to get the idea. I don't see how a file would even cut this material. My dremmel bits are very fine and can work down in grit to eventually polish. Is this acceptable? The bearings which were in the car where not champhered at all and had quite a few miles on them. I don't see how oil ever made it to the timing chain. :realcrazy:

If You're doing the oil hole in the gallery plug on top of the chamfer, You'll be fine, that chamfer doesn't need to be any deeper than to make the notch disappear. If You've got good oil pressure there will be plenty of oil, & the edge of the bearing shells are under a crush load, if the edge is too thin it will deform & lose that, leaving ~1/2 the shell w/o the proper loading.
I used a steel gear link-belt style on My K6, & made no mods to bearings or plug, & pounded the poop out of it for 10's of thousands of miles over ~8yrs......it's still tight sitting on the engine stand now.
For a roller, even tho' there's 'less friction', it does not retain oil like a link-belt, if You pour oil on the inside of a link-belt it will well-up & spill over the sides quickly, a roller lets the oil pass right through......so it takes some extra to ensure it has sufficient lube.
