Narrative:

Climbing out of ord at 4200 ft, we felt and heard heavy vibrations, at the same time we noticed engine and instruments, though within normal range/parameters indicating different readings. The generator and field trip lights for #1 were on as well. Brought power to idle, vibrations decreased. Notified chicago of our intention to return to ord and leveled off at 5000 ft. Soon after engine oil pressure started to fluctuate and abruptly went down to zero. We then secured the engine, declared an emergency and landed normally on runway 32L. Cleared the runway and stopped on taxiway T, so the emergency crew could look for any sign of damage/fire. They did not notice anything unusual on the outside so we proceeded to the gate. After arrival, a mechanic having done a quick inspection of the engine, reported extensive damage to the turbine blades.
