After 5 years & 8600 hours my LNC4 is ready to go – but – having problems with a rough engine on low rpms. It’s a turbocharged TSIOE1B and after some investigations we found oil leaking from both turbos into the airintake. Engine does not like too much oil and it was easy to hear its protests. Some experts say it’s normal with some oil leaking from the lubrication of the turbos in the beginning when using break in oil. After some hours when everything gets tighter and when switching to normal oil  it will disappear. Other experts says this is bad and could not be accepted. Possible reason can be blocked evacuation on the return oil pipe from turbo back to oilsump or too much counterpressure in the oilsump.

 

Would be interesting to hear if anybody else have had simular experience and what you did about it?
