Hi Don
My engine will whine at about 1150 RPM, If it is the same whine as my engine
it is from the straight cut gears on the camshaft and distributor gears.
It's kind of the same whine you get from a cam gear drive set up in a small
block Chevy instead of a timing chain drive.

Subject: JabiruEngine-List: engine whine in 3300 engine
I have recently experienced a "whine" in the engine from 1200 RPM and
below.
The whine disappears at exactly 1200 rpm and reappears once throttling
back to that rpm.
We have taken the alternator out of the housing and checked for wear
none visible.
Cowlings have been removed to check for vibration of the engine on the
cowls etc.Whine still persists!
Engine has been run without master switch on to check if electrical noise
exists.
The engine is 117 hrs old and has been regularly and meticulously
maintained.
Any suggestions?
Regards,
Don Boyd
