Whilst waiting on my BD flight from MAD-LHR on Tuesday, I was observing the a/c in front of us during t/o. My question is that there was an IB 752 that took off and had an extremely smoky left engine, smoking more than a B732. The other engine was fine, but the left engine wasn't. Is there any reason why one engine would smoke a lot more than the other?

Yes, indeed the -535s can get a bit sooty, especially during start-up. In fact, I was watching the PHL webcam from http://www.jfktower.com/liveatc.htm a few weeks ago when I noticed a plume of blue smoke just barely within the view of the camera. When a UA 757 taxied by a few seconds later, it had become clear that it was the one that was emitting the smoke. In your case, it was probably just residual fuel from start-up or the previous shutdown being ignited in the tailpipe during takeoff. Rather common on 757s.

Engines are too expensive to remove as pairs.
So you end up with engines with different times. And figure that the closer to O/H an engine gets the less power it is going to produce, the more fuel it is going to burn, and the more smoky it will get.
OBAMA-WORST PRESIDENT EVER....Even SKOORB would be better.

Guys, this wasn't on start up. It was during t/o and initial climb. The smoke was not blue, but similar to the kind of smoke a 732 puts out when taking off and climbing. I have never seen a 757 with such a sooty engine during this phase of flight. It's a shame I didn't have my camera out.

You are correct. It probably wasn't a UA aircraft I saw with the smoke at PHL. I can't remember what airline it was, though. Do DL or NW have any RR powered 752s? Might have been one of those. Thanks for pointing that out.

Nah.. if your were watching a PHL cam you more than likely saw a US Airways 757, they're all RR powered.. We get about a thousand pass through here a day. (sarcastic). The only other US carrier that flies Rolls powered 757s through here is AA.
Caution wake turbulence, you are following a heavy jet.
