Yeah, I paid 800 for her and she has about 308,000 miles on her. The 4.0L is like a boat motor, made to run all day. Someone told me that a boatbuilding company was going out of business and that a car company was looking for a new motor and so they sold their engine design. The car company kept the same casting tin content and just changed the fuel and exhaust design. Now, I am not sure that this is accurate at all, I have never been able to find anything to back it up anywhere. But it is nice to think of it like that.
I read somewhere the 4 banger they put in the willis could operate for 100 hours or so running at 4,000 rpm's(redline) constant. That is screaming!
