 |
|
After bringing my plane, N335AL, back to Oregon from the factory in Tennessee I checked the filter for metal particles (Approx. 25 hrs). There were some small brass particles in the filter. On the next oil change (another 25 Hours) they were gone. G Barnett

Slightly horrified about this one. I recall the Fox having a bushing problem but that was years ago.
Pete is quoted here and elsewhere about 'normal' regarding having debris in the engine. Doesn't sound right maybe he can explain either; he's been misquoted, or why it's OK and where this 'spare' material is coming from and why it's OK.
Is there no end to jabiru's incompetence when it comes to this lovely engine?
Can they not learn a little from previous debacles?
The downward spiral continues, lets hope we don't have any aircraft that are part of the trend.
Best for 13 guys! Clive

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.

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".

Gary, just curious. How has the aircraft performed with respect to the published numbers. Which one do you have the LSA or the experimental.
