I have a 2000 XJ with only 68000 miles on it. Bought it recently and did a lift, lights, etc. Now I am worried about the head cracking and ruining my engine. Should I change it or leave it? I could buy a new head and do the work myself. It does not appear cracked currently.

 

Wait and keep an eye on coolant and oil levels, don't spend money if you don't need to.

 

if your looking for a pc of mind do it and move to the next issue
