Jabiru's disclaimer that this has only occurred on external oiler engines is not
true. I have a Jabiru 3300, Serial Number 33A1687. As part of a warranty repair
to the heads which included replacing the slow-bleed lifters with quick-bleed
lifters, Pete recommended that I also convert to the internal oiler upgrade,
which I did. All head work was performed by Jabiru USA. After about six
hours of run time I pulled the rocker covers to re-torque the heads and found
a lot of bright yellow debris in the heads and oil filter. I called Pete and
he told me it was just the ends of the rocker bushings, that that was "NORMAL"
and "Wasn't a problem".

NOT A PROBLEM!
Are the particles floating around inside your engine? <--- Problem.
Can the particles access points such as oil galleys? <--- Problem
Can the particles wedge themselves between cylinder and rings? <--- Problem
HELL YEA! It is a problem.
Get that answer in writing and also have the warranty state it will cover
any problems.
