I agree, remanufactured or crate motor. If you consider what the costs would be if it grenades while traveling, miles from home, a crate motor is not too bad. Towing, motel, labor, and having to find a reputable garage is only part of it. Also, if you replace it now, you can make better decisions because you are not rushed like you would be in an emergency repair. I went through this with our 1990 Pace Arrow with 45,000 miles. Engine blew up 50 miles out of town. At least it was close enough to tow home.
