## Discrepancy

EWR FLT 4923 - MAINTENANCE REPORTED THE NR 2 ENGINE WAS BLOWING SMOKE INTO THE CABIN.  MAINTENANCE REPLACED THE NR 2 ENGINE AND OPERATIONAL CHECKS WERE GOOD.  THE TEAR DOWN REPORT FROM MANUFACTURER STATED THE NR 4 TEFLON LIP SEAL WAS THE PRIMARY FAILED ITEM ON THIS ENGINE.  THE ENGINE WAS STRIPPED AND RESTORED TO A SERVICEABLE CONDITION.
