SURPRISE!!

Did an oil change Sunday on a 3126 Cat. in a Freightliner M2 106
and found 1/4" piece of piston ring on the magnetic plug.
Brand new short block w/ 30,000 miles.
Wouldn't this eat the cyl. bore? And the side of the piston?
What do I do?

 

Short block was not a Reman. - w/undersize journals, undercut crank, etc.
It was a brand new crank, and a new block, right from Cat - for 7 grand.
Yes; true, good Idea w/ the scope.
They have scopes now that are super small dia. on Amazon, they go to your phone to view.
May end up buying one just for this.

 

I know; its them new automatic self-gapping rings.

I don't see how this piece of ring could possibly slide it's way out
without making a "compression loss highway" - right into the oil pan.
No pressure there??
No power loss??
I'm about to cut open the filter - and look for the loch ness monster or sasquatch in there.
Must be somthin in there, I notice my oil pressure went up.

 

so I just cut open the filter. Nothing.
Black goo, some metal filings stuck to a magnet,
but not even the size of a pencil eraser came from the whole filter.

Could someone have dropped that in there to bust up stuff?

 

I drove it again today about 150 miles.
No issues with power, smoke, noises.
Nothing.
OK; that's a good thing.
Never mind, and thanx all - again.
