I'm helping a good friend get his old 86 F150 work truck running. We got a donor engine from the local junk yard to go in his truck. It came out of a 2000 Mercury Mountaineer with unknown mileage. We would like to know the mileage on this engine and was wondering if anyone could run the VIN and come up with a ruff idea? The VIN is 4M2ZU66P6YUJ13257 Thanks!
