Re: 2005 6.0 Powerstroke Problems
Just a though but you may have dropped a lifter. Have you checked your rocker arms?
Saw one where a guy had an awful noise, pulled the cover and he had a bent push rod and a trashed rocker. On the lifter if it was that bad I would assume your low pressure oil pump would be trashed--but maybe it's early. Also--you probably need to do a compression check. Just my thoughts.
