The vehicle is a 2005 Jeep Liberty 4 cylinder gas engine. There was a pressure build up that caused cam seals to give way. Engine would require 3 quarts of oil each day until fixed. Mechanic replaced seals and when engine was completely put together and started the seals both blew again. The oil pump as removed to be checked for problems with the pump but when the pump was removed from engine, pieces of cast iron (from engine block) fell out.
Attempted to start the Jeep and the car stalled 3 times before it would stay started. Once the car started the oil light came on and stayed on. Took the car to the service dept who found metal inside the oil pump, which caused the oil pump to fail and the engine was damaged beyond repair. Complete engine replacement. . . Still waiting on the engine which had to be ordered. Owned the Jeep 3 weeks and has 1000 miles on it.
