you should replace all the belts and the water pump. Ummmm.....plugs, cap, rotor. Some gaskets, maybe head gasket and also check the comp before you install the new engine.... :thumbup:Bullitt said:I just wanted to get some feedback on the best ideas for this situation. My 1.6 in my 94 Sentra XE cracked the block (aka new engine.) 1st cylinder locked up and cracked the block just above the oil pan. It had 183k miles on it. I have connections to another 1.6 with 145k miles on it. I know that im gonna use that engine, but i have no idea of how well it was taken care of. I don't have the money for an all over rebuild, and i plan on replacing the timing chain before i drop it in mine. What are some other things I should do while i have it sitting on the workbench? Thanks in advance.
