For those who remember I've had an old 351C on an engine stand in my
garage because it was making some rattling noises under slight load...
I tore further into it today. The above link shows you what I found.
-Now- I know what a spun bearing sounds like. Lord knows how long it
had been that way, but a second one was on it's way as well. I couldn't
tell you why it started, but I can certainly show you the results. The
number 4 rod journal on the crank is now turned -quite- a bit further
than it should be, on the thrust side. The bearings halves are nearly
sharp enough to cut meat. It's ugly.
The crank may be salvageable but it would definitely need a good turning
and it would be way undersize. Personally I think it's probably shot at
this point.
The rod and cap are also both very worn on the bearing surfaces. I'm
not sure it's salvageable or not. I imagine it can be, but it would
need to be bored oversize.
This was the very first engine rebuild I ever did. It was part of my
final project in the Automotive Technology degree program I graduated
from in 1985. The engine was in my Mach I and was driven nearly every
day until the late 90's. It had a change of heads from 2V to 4V, with
manifold, and a cam change, somewhere in mid-life. When I finally put
her down due to the rattling sound, I figure she had nearly 80,000 miles
on her, maybe more.
I rebuilt a different engine and made the swap in 2001. That's a whole
other story that you can probably read in the archives of this list.
After nearly 12 years, I now know what failed.
Enjoy,
