Well, from the photos of the engine you showed, it looked
like a lot of metal got blued, rubber got burnt, and seat cushions dimpled -
but, apparently it had not progressed to the point of grinding metal off parts
of the engine - or else you have one dandy oil filter that capture them
all.
Hi Ed,
It went way beyond
blued. I'd need to measure it, but it looks like the thrust surface on one
side of the rotor was worn down flush with the rest of the rotor side. The
side itself is also severely ground. Make no mistake, the "ground
metal" flag is set to 1 :-)
The oil I sent them was
the last 8 ounces or so that was in the bottom of the pan, which is poor
practice in itself, but it's all I had. The oil pickup couldn't reach it,
so I doubt this is a case of the filter catching it all, though it's a better
explanation than I have.
I believe that routine
oil analysis can probably be of some value as far as trends might go, but I'm
extremely under whelmed by the results of this test. It just seems to me
that something should have been screaming "damage", but clearly it isn't.
Cheers,
Rusty (maybe my rotors
were calcium coated)
