Thread: Metal in oil

not to be the harbringer of death but what if its a bit of gudgen pin sleve?

Not gudgeon pin metal either, can see them fairly clearly.
Weird one.
In my opinion it does not appear to be bearing shell material as a piece that size could not get out without being shattered or shaved into tiny pieces.
Plus this metal is highly magnetic. My BIlaws and another mech friends opinion is that the bearing shell material should not be very magnetic if at all being white metal. He isnot 100% as has not magnetically tested bearing shell material in at least the last 10 years. Anyone have a bearing shell they can test a magnet on to confirm this??

May pull the bearing caps off and check. lso may have come from tiing chain area of motor or could be just residue from a previous job or just swarf, who knows. Will also pull off rocker cover and loo down the front. If not the bearing shells or timing gear wil put back together and see what happens.

WOW your keen, id be taking the metal to an engine rebuilder and asking what they thought.......

Alot of engines shred small parts of metal and it may never be bearing....

Clarkie,
You may be right and it may be one of those twilight zone things. Have not pulled the whole engine down just the sump, oil pump and stiffener plate and will check main and bige end bearing caps in car, BIlaw has told me how to do without removing the crank.

Done that and nadda. Filter was clear as a bell, no fillings, gunk etc, oil pickup clear etc.

If so

MMMM, I thought so but maybe not. Asks the question though where did it cone from?????

How are the timing gears mounted in these engines? Do they sit on a spigot? Sounds like hard facing off a bearing surface. If its 1/2cm by 1/2cm is sounds a bit big to be timing gear tooth hardfacing?

Do these engines run wear sleves for the crank seals? possible it could be a failling wear sleve.

There isnt too much in a modern metal bearing (besides the backing) thats magnetic. Metal bearing surfaces arent usually shiny (ie chrome) in apperance.

Are you able to take and happy snaps of the debris?

Are you anywhere near any heavy equipment dealers? If you dont find any thing obvious and put it back together, do a couple of thousand k's and then take and oil sample and get it analysised. This should help you out.

Edit: its not the type of chrome one would chip off a cheap socket or sanner is it??

Yeah that was our thoughts. Looks like some sort of hard facing. Not off a spanner etc. Looks like polished metal one side and grey the other, will try and post a pic.

Im no land rover diesel eng guru but i have done a lot of caterpillar eng "why did it go pop" tear downs and may be able to give an idea of where its from.
