Truck Repair/cummins n14


Just want to know if bad injector will cause diesel leak from top of head and bottom of valve housing or is it a stuck intake valve

Sounds like a leaking crossover at the front of the engine youll see I cover with two flathead screws at the back of the engine you'll see the same thing. in between each head doubt you will be able to see it without taking the rocker boxes off but it has the same thing except 2 little tubes that make a half circle. Under all of those plates are little orings one of those has blown out.
