Short story I'm currently rebuilding a 2008 engine to put in my 2003 Liberty. I have done a good bit of research on here and have found a lot of information such as transferring the reluctor rings from my old engine. I am looking at purchasing the RockAuto rebuild kit but waiting for the crank and block to come back from the machine shop. I am writing to see if any of you have advice or suggestions for me while I have everything tore apart regarding the rebuilding, or parts to use, or etc. Also I haven't taken the heads into the shop yet is there anything specific I should have them check or replace? Thank you for any and all information.
