Truck started leaking oil the other night. Looks like it's coming from/around the balancer area. Oil level was good for a few days and now its is low. Think it's blowing out of the blow by like the pcv tube is plugged or something. Any ideas? Has a noticeable drip while running. No fuel/coolant in oil. Has a little injector chatter but nothing out of the norm for an LB7. Any thoughts/input is greatly appreciated.
