Subject: JabiruEngine-List: Deposits in Oil Filter


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

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

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

*         Test with a magnet : no magnetic parts

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


Is it =93normal=94 ?


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 =93normal=94 
analysis?

Hi Jrme,

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.
