Hi Carl,
Nice to know I am not unique with this! I don't seem to have much luck with
turning the prop by hand to get the oil back into the tank. The pump seems
to out pace the crank case pressure at that speed (give me a scavenge pump
any day).
Agree with you about running the engine for short bursts - doesn't do the
thing any good and if I am unable to go flying for over a week (like in this
recent weather - Vis was zero in Oxfordshire) I find a nice quiet corner of
the 'field and run it up for 30 minutes or so to get the 'T's nice and high.
Now someone will tell me that this isn't good for the engine either :-(
The oil I am using Motul 5100 - one from the list recommended by Rotax. This
is semi-synthetic with a gear additive and being semi allows me to use Avgas
to top up when away from home.
I'll give you a ring during the w/e.
Regards,
Peter

H Peter,
Since my first flight (and especially since new dipstick) I have had the
same concerns.
I understand though that this is perfectly normal. If you look hard enough,
the Rotax manuals suggest running the engine for 1 minute before checking
the oil level. Personally I feel this practice will increase engine wear
(and starter motor).
My solution is to manually rotate the prop blades (in the correct direction)
for about three full turns until you hear air benig blown back into the oil
tank. Its a bit of a pain but good exercise ! (just be aware of the prop
tips - they have cut me several times).
Needless to say make sure the mags are well and truly off before attempting
this.
Another option is to turn the engine using the starter, but if you have a
proper starter switch you wont be able to do this without activating the
magnetos.
Safe flying,
Carl

it)
PPS What oil are you using (I have changed to Castrol RS Superbike since my
oil temp rose to 135 last week in the hot weather- guess I will need to move
the oil cooler from behind the radiators)
