because i might sell my white one with half as many miles as the red one with a supposedly newer motor in it....

That's a stroker motor. Got the stuff to build another one. 3 XJ/MJs in the family.....

ah. i see. I really hope she isnt lying, i dont need to have a 300k jeep....

You could always ask to do a compression test. I have asked to do this a few times on a few vehicles I have purchased. While this is not a guarantee it is low mileage, it does not hurt.

i couldnt find that place where it should be we even sprayed some engine cleaner on it and cleaned it off. i did right down the numbers on the head, if they even mean anything
