long time lurker, did my rear main today. 98 xj 4.0 4x4 aw4, found my main bearings were shot, crank was still not too badly scratched. used emery cloth to clean it up best I could (fingernails weren't catching any spots and it was shiny) and put new bearings in... oil pressure up a tad and thank goodness it didn't make it to the copper! caught it in the nick of time?? oh well, just thought id share my unfortunate find today!

 

Unfortuneately that won't last long, the cam bearings are probably in worse shape.

 

no argument there but at least I know this 167k eng is more tired than i thought haha
