Ticking and knocking

[rangerstxcincy]

OK now i have fixed mostly everything after i replaced the injectors (it needed them) now i have a ticking noise (think an injector from summit was bad...) the ticking is constant and increases with speed and rpm. And now i also have a knocking noise from the motor the noise comes and goes but i really hear it when i idle and after my truck got warmed up to normal temp it loses oil pressure only when i idle and the oil pressure comes back as soon as i start driving again... Anyone have any ideas what could be casuing this problem?

Thanks

Interesting. Does it sound like the ticking is coming from under the valve covers? It could be the pushrods. I have no idea about the oil pressure situation.
