[TR] Opening Up Connecting Rod Oil Passages

[Bill Brewer]

     So I am rebuilding a Standard Vanguard engine for a 1953 Morgan Plus 4.
The connecting rods have been laying on a shed floor for decades. They
cleaned up nicely, but the oiling hole through the connecting rod to the
small end bushings were all rusted solid. I made a tool out of a piece of
1/8 brass welding rod. I pounded the end flat, like a screwdriver, and
pounded it in while turning with a small Vise-grips. It got the hole opened
and rust poured out. The hole is about 0.180" diameter. I've been trying to
find a long 3/16ths tube brush (like a pipe cleaner) to clean them out
better, but no one makes one long enough. The brush needs to be about 5"
long and the longest that McMaster Carr has is 3". I could pull the small
end bushings out and go at it from both ends, but the bushings in there fit
the wrist pins perfectly and I would rather not mess them up if I can help
it.

     I have been considering buying a 12" long 3/16ths (.188") drill bit and
running that through. It might open up the hole a little bit, which might
not be a bad thing.

     Has anybody else been here? How did you get by this?

     TIA,
