Bill,
Clean the engine and run it with the cowl on with leak detector in suspect
areas. I use a talc like oil leak spray that sticks to the engine and allo
ws visual confirmation of where the oil leak is coming from. Messy putting
talc on it but it works. It must have a sticky substance to hold the talc
in place. There are dyes to add to the oil and UV lights in the kit to det
ect the source also. Since oil blows around, you must do this with the cow
l on, run it on the ground, de-cowl and look.
Questions:
912, 912S or 914? Total time on engine. What engine serial number. Did y
ou mess with any of the case bolts? Last time oil lines serviced? If a 91
2 series, do you have the new fuel pump?
There are many sources of leaks identified in the Service Bulletins over th
e years from cracked blocks between the cylinders, to oil pump seals, to th
e gearbox PTO seals. Oil tank fittings have also been known to crack.
You must do some detective work. Get on Google and the Rotax Owners site a
nd start looking for your serial number and some fixes
Gear boxes are best left to a Rotax shop in my opinion. They have the tool
s etc.
Oil seal replacement on the pump is not hard, depends on the engine.
Oil lines are fairly routine owner stuff.
If you messed with the crank case bolts, it is your fault, and fixing it is
not an option except for a pro to reseal a case.
If the case has cracked, I hope you have a warranty, otherwise it is a shor
t block which can cost quite a bit but you will get the new case which is v
astly better than the old ones.

Subject: Europa-List: LEAKING OIL ON PROPSHAFT BY GEARBOX
Hi Guys
i am after some help
I noticed over the last few weeks an oily mist on the screen, stbd side aft
er a flight. now oil is smearing the lower cowl beneath the propeller. The
oil is also spraying on the propeller slip ring and clogging the carbon bru
shes and so causing slow or intermittent changing of the Airmaster propelle
r. The total oil loss is minimal its just inconvenient and messy.
Do you think the seals around the prop have failed and is this because a be
aring is failing also? Is it a straight forward job to repair and are speci
al tools required? I regreased the Airmaster propeller a few weeks ago and
firstly imagined I had overgreased but now i am convinced its oil fro the s
haft. I have checked the breather in case it was blocked as that might have
caused the problem
Regards to all and anticipating some lively replies
Bill
