Jeep engine help needed........

[riz]

I'm looking to buy a 96 Jeep Grand Cherokee with a 4.0 Inline 6 under the hood. I don't know much about the Jeep enigines but I do know that those 4.0s can usually go forever. I'm going to go look at it in the morning and the guy said it has the typical lifter ticks while it's cold until it warms up then you never hear it............. Is that true? Is it a common thing for the 4.0 Jeep engines? If not, what could it mean by way of problems or whatnot?

Thanks in advance.
