Narrative:

First officer flying, we departed ewr on runway 4L on ewr 6 SID which calls for right turn to 060 degrees, followed by left to 290 degrees at ieza localizer 4 DME. Cleared to 2500 ft. On takeoff leg, we noticed aircraft in front of us (2.5 mi on TCASII) turning left in front of us. While watching that aircraft, I selected heading to 290 degrees at 2.3 DME (the turn point when using this SID off of runways 22). First officer realized we weren't at 4 DME yet and verbalized correction, and I reset heading to 060 degrees. Concurrent with this, we passed assigned altitude of 2500 ft. Both of us realized we were missing the leveloff and verbalized '2500 ft, leveloff,' and I eased forward on the controls. First officer resumed leveloff at 2500 ft after excursion reached 2840 ft. As we leveled, controller called 'turn left 290 degrees, maintain 2500 ft.' no conflicts or TCASII alerts resulted, but improper leveloff was induced by attention diverted by traffic and improper heading bug selector.

Title: B757-200 ALTDEV WHILE DISTR WITH HDG SELECTOR ON INITIAL CLB FROM EWR.

Narrative: FO FLYING, WE DEPARTED EWR ON RWY 4L ON EWR 6 SID WHICH CALLS FOR R TURN TO 060 DEGS, FOLLOWED BY L TO 290 DEGS AT IEZA LOC 4 DME. CLRED TO 2500 FT. ON TKOF LEG, WE NOTICED ACFT IN FRONT OF US (2.5 MI ON TCASII) TURNING L IN FRONT OF US. WHILE WATCHING THAT ACFT, I SELECTED HDG TO 290 DEGS AT 2.3 DME (THE TURN POINT WHEN USING THIS SID OFF OF RWYS 22). FO REALIZED WE WEREN'T AT 4 DME YET AND VERBALIZED CORRECTION, AND I RESET HDG TO 060 DEGS. CONCURRENT WITH THIS, WE PASSED ASSIGNED ALT OF 2500 FT. BOTH OF US REALIZED WE WERE MISSING THE LEVELOFF AND VERBALIZED '2500 FT, LEVELOFF,' AND I EASED FORWARD ON THE CTLS. FO RESUMED LEVELOFF AT 2500 FT AFTER EXCURSION REACHED 2840 FT. AS WE LEVELED, CTLR CALLED 'TURN L 290 DEGS, MAINTAIN 2500 FT.' NO CONFLICTS OR TCASII ALERTS RESULTED, BUT IMPROPER LEVELOFF WAS INDUCED BY ATTN DIVERTED BY TFC AND IMPROPER HDG BUG SELECTOR.
