<![if !supportLineBreakNewLine]><![endif]> When we originally installed our oil tank (5 years  ago) the vent line was routed to the side of the cowling. The end result is that  there is a smell of oil coming in from the NACA vent when the aircraft is  climbing. I suspect the location of the outlet pipe is also in the airstream  resulting in an excessive loss of oil as it is getting sucked out (and coating  the side of the fuselage).

  

 I was under the impression was that the  solution would be to route the vent pipe via a collector bottle but  reading the manual Europa recommend just routing it to the bottom of the cowling  (the bottle being optional).

  

 My concern over the bottle arrangement is how long  it takes to fill up the overflow bottle with oil and how frequently one would  need to remove the cowling (to empty the bottle).

  

 So, based on communal experience which is likely to  be the best arrangement - routing via the bottle or omitting the bottle and  ensuring the outlet isnt placed in the airflow where it could be sucked  out.

  

 One thought was to terminate the line at the exit  of the exhaust stub (using copper tube)  which would hopefully vaporise and  burn off any oil that escaped. The arrangement would need to ensure no suction  took place - perhaps terminating using a T piece.

  

 Suggestions please ?

<![if !supportLineBreakNewLine]><![endif]> Go the bottle route Carl, we have never  had more than a thimble full in ours in over 12 years and 1200 hrs. It  is fumes rather than oil that is emitted.

We use the catch tank option, a small polythene bottle on the pilots side,

on top of the footwell. In 300+ hours I doubt we have seen half a cup full

in total. We have the Airmaster prop so the engine sees high revs on take

off and typically 5000 cruise. Occassionally we might get a slight smell of

oil fumes, but not very often. I doubt the engine has in total burnt and

pushed out 1 pint of oil in that time.



Tony.

 We have a bottle on our 914.  It collects a little  water and some oil mist.  In 250 hours I have only ever emptied it when  doing an annual.  It has never had more than about 10mm of fluid in  it.

<![if !supportLineBreakNewLine]><![endif]> Carl,

 I have my overflow going into an aluminium  container, (in fact a 'Baroca tube' the ones you can buy at the pharmacy or  supermarket to boost your life!) and is located on the pilot wheelwell firewall  lower then the oil tank (Classic). It normally has little in it at 100hr  checks.

 Cheers,

 Tim
