Question about 2000 Lincoln Navigator
Coolant is leaking near rear of vehicle and oil is in the coolant reservoir. Oil is constantly leaking out and over heats within 15 minutes.
Well, the good news is this could be something as simple as a blown head gasket. The bad news is most likely that is not the case. You have either cracked your block, cracked the head, worn a hole in your timing chain cover that is allowing the water and oil to mix or blown your head gasket or a combination of these problems. Your choices are to pull everything apart and magna Flux the Engine block and heads or replace the motor, assuming the issue isn't a hole worn in the timing chain cover, or replacing the motor, the easiest of the solutions although not the cheapest. A decent short block should run around $600 to $1000 with shipping. It's used but has been checked and should serve you for a while. The other option is rebuilding the motor. Should you choose to rebuild the motor I recommend you get the Haynes or Chilton's repair manual on your vehicle for doing the job.
