Rotax 914 leaking oil thru air filter

[Turbo_Boss]

Hey guys,

Sorry for my late reply. Well we clean the air filter, and remove all the oil in the turbo housing. We start the engine and there was no smoke. I fly it and use it for around 30 minutes and there was not oil smoke.

I put the Magni in the hangar and leave it there to see if it leaking oil but there in not leak any more.

The mechanic toll me that maybe the (3) PRESURE VALVE got stock open by some carbon deposits in the oil and thats why it was leaking.

I also change all the oil and took out the oil canister to clean it inside. I took the oil filter and cut it with a special tool for this and I check for metal particles on the paper element and it was OK

Until now, there is no leak

If this happen again, I will replace the (3) PRESURE VALVE

THX,

Isaac

After a steep pull up and then pitching forward and down you will experience negative g's(you get lighter in the seat) as will your engine and the oil contained therein.

I agree with Turbo_Boss. I (we) understand what neg g's is, but how can that affect the engine? When you do stalls (training) on a fix wing you experience neg g's regularly. This doesn't effect the engine...or does it

I don't know, was just answering the question as I understood it.

Would be interested in the answer
