HPOP Make noise ???

[55gasser]

Still have not figured out my churping (knocking) yet.

one guy said it was my rocker arm replaced that & a injector & tryied to charge me 920** after he dropped it off (i was not home) i started it & still knocks like it did.

here is my question : the noise is coming from the rear top of block, has anyone ever had there hpop (oil pump) make a noise before it went out ?

i have to decide if im taking it to the dealer monday & paying a couple grand (if not more) or tradding it in on a cummins & going upside down.

thanks for the help

I haven't heard of anyone with a 2005 HPOP going out. The early 6.0L HPOP's were more prone to failures. Is it possible that yours is a late build 2004 engine?
