I have an 08 jk Wrangler 3.8lt and I rebuilt engine replaced everything except rockers. Ran great for 2 thou then slight knock to eventually the rocker lobe breaking. The rockers looked great before so I didn't replace chauked it up to I should have. Replaced all and ran great but before I closed it up I noticed the chamber oil feeding tube wasn't pumping oil. If it ran dry on less miles I'd understand I don't think oil is that good if it was blocked from the start. Looked for diagrams on that and came up short anyone know of one or have any ideas thanks.
