Thread: Found this on my sump plug ID anyone?

I think Chris was right and you seem to be coming to the same conclusion. It could have been in the sump from Day Dot.

It could have been in the sump from Day Dot.

I have had the sump off a few years ago to do the oil pump bolt and it wasn't there then.
I also fitted a strong magnet to the sump plug a few years ago.
I am pretty sure it arrived in the sump an the last 8KK since I last changed the oil.

The fracture mark is quite black and old except for a tiny bit at the end which is silver, so I think it has been sitting in place for yonks ( most probably since assembly) and just recently decided to part company, maybe from the big loads travelling up the Alpine Way towing a tonne.

Sigh , just goes to show what another poster said. They must have all been drunk when assembling the engines.
Hopefully I will never find out exactly where it came from as even if I dropped the sump , it would be impossible to see a conrod small end bearing.

I don't envy you Phillip it could be nothing or it could be everything
Maybe someone dropped something into the engine
You could pull the sump and have a look but you might find nothing

May be the magnet is to strong and its pulling the engine to bits?😉😉

I've heard you can get too strong a magnet and it can pull the guts out of a flux capacitor and also may the vanes of a Hiclone collapse, but mind you that's only what I have heard.

Naa, the Flux Capacitor will demagnetise the magnet.

You're probably right te the Hiclone though.

I was thinking maybe a piece of piston skirt, but 40 mm would rule that out. But 40 mm would seem way too big for a gudgeon as well. Big ends are 54mm, and little ends look to be less than half of that.

According to the images in Google the small end bearing is 30MM in diameter which is probably in the range of error if eyeballing the bit next to a hose clamp. It looks like about 30MM if you look at it next to the 20 cent piece.

I could not find anything else in the head or block that had a diameter that big, was metal , and had a "lead in" on the outside .

It should not have any effect on operation as if it is a small end bearing casing , the broken bit only impinges on the actual bearing shell by about 0.5-.075MM , by the marking on the inside. The thrust on these should be at 90 degrees so spread over the whole bearing surface with no leverage from side to side.
