One problem related to engine noise has been reported for the 1999 Dodge Durango. The most recently reported issues are listed below.
Going on a trip oil pressure gauge went to 0 then back up to normal then back down to 0, check gauge light came on. Pulled off interstate, listened to motor sounded normal, checked oil which was fine, decided it must have been the oil sending unit gone bad gauge had went back to normal, so started back on the road. Then gauge started dropping again, stopped and put 1/2 quart of oil in, engine still sounded fine, started back on the road. Went about 30 miles, motor started knocking. Pulled off the interstate, engine knocking really bad. Turned motor off then back on, engine sounded so bad cut it off and called a wrecker $50. 00. Towed it to a Dodge dealership who said the motor was blown would cost approximately $5000. 00 to fix. Had to rent a car $35. 00 a day. Motor never let on there was anything wrong, never used oil, never smoked.
