Parts & Accessories Spare parts 5.3 LT engine, model 15, mileage 250,000. The engine is clean, no noises, no oil consumption, no lifters, and I've maintained its oil changes. Excellent pressure, and you have the right to inspect it at any workshop. The engine has only had its oil pump replaced. Its other parts are like new and it doesn't complain about anything. Sale is very easy and urgent.
