Jabachat of May 2007 advise to cut the filter and wash it in fuel in order to look for deposit:  

http://www.jabiru.net.au/Jabachat/Jaba%20Chat%20May%20%202007.pdf  

   

I did it after the first 25 hours. My friend Marc cut the filter carefully (no dust). After filtering the fuel:

·         Test with a magnet : no magnetic parts  

·         Visual inspection: very small orange metal dust (valve guide?)  

   

Is it “normal” ?  

   

I would like to send the oil for analysis but I have no reference to compare. What and in which quantity should I find in a “normal” analysis?

 I would like to send the oil for analysis but I have no reference to 

 compare. What and in *which quantity* should I find in a “normal” 

 analysis?



Hi Jérôme,
	




It is normal to find "some" metal particles in the oil filter at first 

oil change. Of course the quantity and size must not be excessive.

Re the picture, bushing material comes to mind, camshaft bearings, 

rockers, etc.

Re oil analysis, it is mainly a comparative method, though the 

specialist can determine what looks normal and what doesn't.

Few people know that fixed base operators are offered free oil analyses 

by oil distributors, so if you have a friend in the business you won't 

have to pay 



Best regards,

Jerome as I understand it there will normally be some magnetic particles due to the bedding in of the rings. I found a significant amount in mine at 15hrs. There should be no non magnetic bearing material  which is normally white.

Jerome,  

   

It’s normal to find very small amounts of both ferrous (magnetic) and non-ferrous material during the break-in phase. The crankshaft and rod-end bearings are probably contributing to the orange dust, as they bed-in. Any ferrous dust is coming from cylinder bores and / or piston rings as the honed surfaces are bedded-in. It’s good that you have taken the time to check at this stage, but more important to check later in the engine’s life (say at 300 – 400 hours). Bearing material being deposited in the filter at that stage indicates wider problems.

Jerome,  

The picture looks like white particles on an orange thumb !  

I did not find orange coloured particles. If this is the first filter scan there may be traces of sealant or something else. It would be best to ask the dealer who would have wider experience. Are you sure it is not rust?

Peter you’re right!  

   

This morning, I tested again with a magnet the deposits obtained after filtering. Nothing!   

But… When I tested the fuel used to wash the oil filter with the same magnet, I found magnetic particles! (sorry, I didn’t had my camera this morning)  

The particles are so small that they pass thru the paper during filtering!  

   

Of course, it’s normal to find this magnetic dust. But is it normal to find those orange particles (size, quantity)?  

http://jeromedelamare.free.fr/deposit/DSCN3651.JPG  

   

Did you, or someone else, observed those orange particles too?  

   

Is there a link with those particles and a lubrication problem as observed by Martin?  

   

Jérôme
