pjvr99 Posted January 2, 2016 Share Posted January 2, 2016 where is oil leaving engine: turbine, #3 bearing lab seal vents, #2 bearing vents, 5th & 10th stage bleed valves wet, during climb or descent, level flight (altitude)? need a lot more information Quote Link to comment Share on other sites More sharing options...
HercMX Posted January 3, 2016 Share Posted January 3, 2016 I'm betting on bleed valves being wet.... With smoke in cabin...... Jack........... Quote Link to comment Share on other sites More sharing options...
NATOPS1 Posted January 7, 2016 Share Posted January 7, 2016 IS the oil coming out of the drainmast? If so look at your scavenge back pressure. Quote Link to comment Share on other sites More sharing options...

Engine shop signed it off as "could not duplicate".I wasn't happy!Next flight when we began the decent I was in the cargo compt.Oil was streaming from the mast.Engine was shut down and air started just before entering the pattern.Problem was found to be a relief valve keeping the oil tank pressurized on decent pushing the oil out.R/R and all was good.
