Posted: Thu Aug 23, 2007 3:12 am Post subject: RE : Deposits in Oil Filter

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?

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.

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?

Jerome,  

The picture looks like white particles on an orange thumb !  

Sorry, I’ll use a white paper next time. All particles on the paper are orange.  

   

I did not find orange coloured particles.   

In my oil filter, it was impossible not to see them. So perhaps it’s not really “normal” to find them ;o)  

   

If this is the first filter scan there may be traces of sealant or something else.  

The particles are really brilliants. It’s impossible to confuse with sealant.  

   

 It would be best to ask the dealer who would have wider experience.   

Of course I asked my dealer. He has no information to tell me if it’s a normal wear during break’ in or not.  

I will send my oil to analysis, but without a real feedback of Jabiru I can just compare with a precedent analysis. By this way, it’s just possible to detect when a NEW problem occur.  

JABIRU SHOULD GIVE US A TYPICAL ANALISYS OF WHAT WE SHOULD FIND IN THE OIL. So, we could diagnostic problems during the first hours of the motors.  

   

Are you sure it is not rust?  

Yes ;o)  

   

Peter H  

   

Thank you for your feed back Peter.

Thank you Andy,  

   

I appreciate that you've answered my question. I just would like to be sure not to find a problem too late as other people on this list.   

For the moment my engine works fine!

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.
