My 99 Xj8l Jaguar wouldn't start and I took it to a mechanic--he said 4 of my 8 cylinders stopped working and I needed a new engine. I did a vehicle search for my car and found out there was engine problems from the manufacturer its called the nikasil problem - document numbers are s491v6 or v5. I need to know if my car fall under this problem. I kept up with all of the maintenance suggestions( oil change,mileage checkups). , and my engine still failed at 87715 miles.
