B757 Smoke Trails
Watching a Thomas Cook 757 (forget the reg) take off from Salzburg the other week, I noticed that the left engine was emitting a smoke trail whilst the right was not. It was not an excessive trail, just noticeable that there was nothing from the other one.
What would cause one engine to make more smoke than the other? I imagine that anything in the fuel wouls affect them both.

eyeinthesky,
Okay, I didnt RTFQ.
Sensible answers are as VP says it could have two different phase engines. (At least one TCX aircraft has this).
Other possibility is, both engines are identical, but of course are mounted at different angles to the horizontal due to dihedral. The net result is it is not unsual to see an aircraft with less oil qty in the left than the right.
Whilts this may be the answer, I'm not overly convincing myself, didnt think it'd be that obvious on t/o. Have seen it smoking on the ground after shutdown though, particularly if it had been recently topped up.

Thanks for the replies. I hadn't considered that the engines could actually be different.
I must confess I watched it disappear into the cloud and half-wondered whether it would reappear because the right engine wasn't working... But then I couldn't see any major rudder deflection.
Thanks for the info.
