What is this ?

[Debacle]

Just finished changing fluids on engine, auto, transfer and diffs and found this in the drain pan. It is 16mm long, outside diameter 14mm, inside diameter 7mm.

Any ideas on what it is or where it is from.

Car is Disco 1 3.9l with zf auto.

At first look i thought it was a roller from a bearing. Closer look reminds me of a roller from a rocker arm.
Is it hardened?
Did you remove sump at all on the box or engine.
It might be spacer/ dowel.

I removed the sump from the auto when I changed the filter but I emptied the drain pan after that.

Check to see if any of the sump bolts (engine and trans) have spacers that size, good luck, Regards frank.

Sorry, should have worded that different. I emptied the drain pan after doing the auto and didn't notice anything in there. I then did the transfer and diffs and it was in there after that. Pretty sure the drain hole for the transfer would be too small for it to fit through. Car was driving fine before this. Maybe it's fallen in there from somewhere else. I'll find out when I finish working on it and take it for a drive.

I reckon its a foreign object, too big to be any kind of bolt spacer that would fit thru a drain hole.
Its too thick to be a dowel and doesnt have a split in it, they are more like a roll pin.

Not magnetic is it ??

I reckon it is the spacer from the filter bolt in the auto box

Is there a spacer in there ? The filter went in ok but the light and viewing position wasn't good.

I'm with Pop..... Have you checked it's not magnetic?

[Debacle]

No, it's not magnetic.

I think I might have found the culprit. Harry wins the prize.

Looks like it's coming apart again.

Are you thinking along the lines that may be a magnet put in there to collect any bits of metal in the sump. It's got me thinking that maybe I should pop one in there before I put the sump back on. Anyone got any thoughts on this.

[pop058]

That was the thinking
