Erich,
I have a 914 with almost 500 hr. on it. Since day one, the airbox vent has been
weeping oil. I think it must be the nature of the beast.
While on the subject of the airbox, the temperature probe in the airbox needs to
be pulled out and cleaned with alcohol, or acetone about every 150 to 200 hours.
The oil on it due to heat in the airbox will blacken. Once this happens being
dark it absorbs heat, an as a result it sends a higher temperature back
to the computer. The computer is set to retard timing when the airbox
temperature
reaches 165 degrees F. Here in Florida, in the summer, at takeoff
with full boost it is not long before 165 Degrees is reached.
This is one of the reasons that we have installed an intercooler.

oil on my 914. Not a lot mind you but enough that it got me thinking. In
30 hours of flying I have probably less than 1/4 oz. My question is has anyone
else seen this? Is it normal? Two things I can think of is that the oil is
seeping past the oil seal in the turbo and making its way into the air intake.
Or perhaps it is the oil used to initially charge the air filter.
