4L Con rod bearing oil hole question
Posted: October 17th, 2022, 12:46 pm
I'm currently rebuilding a block from a 92 cherokee for my 94 cherokee (blew up the 94 Block... oops). Both engines have 544 casting rods with the stock bearings (f112 std. Stamps). The replacement bearings I've ordered don't have oil holes while both stock sets do. I've asked both my parts guy and the tech line for the manufacturer of the replacement bearings why this is and they told me that the bearings from 84-93 are all the same and never had oil holes. The tech line even pulled up the oiling diagrams. I guess im going to send my replacement bearings in or file a hole myself. I'm just wondering why jeep has oil holes stock from the factory but I can't seem to find replacement ones that do or even anyone to acknoledge that they did. https://photos.app.goo.gl/DWFJzCMLsigzAPKG7
