Four problems related to engine burning oil have been reported for the 1999 Dodge Durango. The most recently reported issues are listed below.
At 41000 miles my 1999 Durango 5. 9l experienced spark knock and heavy oil consumption. Oil changed at every 3000 miles. Called Chrysler for help. They said too old and did not offer any help. I replaced all the valve seals. Did not fix. Replaced the plenum gasket as stated by the technical bulletin. Did not fix. Finally, tore down engine and found a broken oil ring on #8 cylinder. Replaced all rings and bearings. Finally fixed all at my cost. Chrysler did not offer help. Only one thing to say to Chrysler, you have one less customer.
My 1999 Durango started experiencing a spark knock and engine oil consumption due to bad intake gasket design. I have talked to a couple of other Durango owners who have experienced the same problem at the same mileage. The gasket can't be properly tightened and oil leaks into the intake causing a knocking under load. The fix costs around $1,000.
The oil pressure dropped and all the lights on the panel had come on. While driving the vehicle had become sluggish and then had gone back to normal. The dealer was unable to remedy. The oil was burning every 200 miles. The ovt valley pan gasket was changed, and the intake gasket was replaced. There was a loud knocking and or clicking in the motor. The dealer found sludge in the motor, and found that it was blown. The seat wouldn't slide/hard to lift, and the a/c compressor was found loose. Ts scc.
