I have a 5.3 swap in my GN. motor has LS6 heads cam and intake, had 53K on it before swap. re-used my stock oil pump.
Last night the oil pressure was around 20 at idle and didnt pick up much after I gave it gas. but after I let out to coast to a stoplight, it would dip down to 0 then back up to about 10. My oil pan is full of clean oil, could my oil pump be going bad? what are the symptoms of a bad pump? I have a mechanical gauge as well, its brand new and reads the pressure from the location of the stock electric sender.

found out what it was. oil pickup tube screen was completely clogged with ****. must have happened from tapping my oil pan for a return feed line. cleaned it out and am gonna upgrade to an LS6 pump to be safe.
