    I need some advice regarding fixing my 2002 Jeep Liberty Limited.

    My Jeep has 97K miles and I'm the original owner. Its been running great, but about a week ago it suddenly began running so badly I could barely make it the few blocks to my home.

    I found 0 compression in cylinder #2, and good compression in all others. I pulled the valve cover off and found that the rocker arm was off to cylinder #2. I put a small scope down the spark plug hole in cylinder #2 and found a gouge in the surface of the piston the shape of the edge of a valve.

    I'm trying to decide if I should attempt a repair and if so what needs to be replaced and what is advisable to replace. I haven't done this depth of repair work before, so I know it would be a big job for me.

    Given the Jeep's age I'm interested if people think fixing it is worth while given the scope if problems I've described.

    Thanks for your advice!

    Here ya go,
    Do you like the KJ?
    Did you do good maintenance on it all those years?
    Is the body still in good shape?
    If you to the above throw another motor in it and drive for 10-12-14 more years
    If you want to ditch it, there is a spot in my " spares " garage for it, it's worth it in my book
