G'day Chaps,
In case any of you haven't seen it yet I've got a web site up and running
with all the information you need to predict Morning Glories. It is
http://www.morninggloryaustralia.com
I've also now had all the rights reverted back to me for the Morning Glory
Documentary that I made for National Geographic in 1998 so I've made it
available to watch on the net - the above site has links to it
cheers

I'm feeling a bit sheepish about having a dry sump
engine!!! (although conceding that these have their own set of
probs)

P.S. Those who haven't yet seen or Morning Glory 07 photos please see:
www.pacificsoaring.com.au ->Photo Gallery
P.P.S. I believe that several Super Dimonas
are available in the U.S.. at very attractive prices at the moment - given the
exchange rate.

Hi All.
Yes Ian, the same applies to the
L2000.
Besides higher temps you also lose a little
horsepower. Thrashing the excess oil around with the big ends causes
friction.
That generates heat. Heat is energy and that comes from the engine so less
power to the prop.
In the Dimona the mid way point between the 2
lines is the top position for the oil.
If you put the correct amount of oil in as per
the Limbach Manual when yo do an oil change and check the dipstick
afterwoods tis will show the correct spot on the dipstick.
If you lift the tail till into cruise attitude
(engine level) you will then find the oil sits at the top line on the
dipstick.
Thus many pilots tend to want to overfill the
thing thinking it should be filled to the top line.
Hope that made sense.
Cheers.
Nige.

I got a phone call today from Chris Kiehn RAAus and he alerted me to to
service bul and Jabby chat end of January and among other things I thought
it interesting if you keep oil near bottom mark oil temp can run 15deg C
lower than running at just above full mark. Newer Jabirus have a deeper
sump which do not have the same problem. I gather if oil is near full
mark oil gets churned up by crankshaft/pushrods and thus engine runs much
hotter. Who would have thought it!! I was told similar applies to VW
transporter engine but not sure about L2000. Anybody know? Ian M
The paste is below
Engine oil level has a strong effect on oil
temperatures. For all engines, the lowest oil
temperatures
are achieved when the oil level is set on the lower dipstick mark.
Generally,
this oil level is suitable for circuits or
flights up to 3 hours duration. Note that testing has
shown that
setting the oil level slightly above the upper dipstick mark (i.e. slightly
"over-full")
can result in oil temperatures 15°C higher than
when set at the lower mark. Figure 5 shows
the length of
the Jabiru 3300 dipstick.
CAUTION
This applies to all Jabiru 3300 engines and to Jabiru 2200 engines prior to
S/No. 22A-
2440. HOWEVER, more recent Jabiru 2200 engines (S/No. 2440 onwards) have a
different sump (easily identified by it's lack of fins). Setting the oil
level on the lower
mark in these engines will give oil levels lower than is optimal.
