2016 5.3 Whipple LT4 fuel system
been running strong 4 years and on my 2nd cam swap. Gpi pds2 with delphi lifters. Took a trip to pick up a trailer. Right before getting home I can hear valvetrain from inside the cabin loud. Not one specific cylinder but like the whole top end isn't getting oil. Extremely noticeable.
Oil pressure shows 35 and I do not smell fuel at all in the oil.
A lot of codes popped up at same time too. Not sure if maybe electrical can cause this mechanical issue with good oil pressure.
Anyone ever run into this issue?
Checked rockers today and only 2 lifters are slightly spongy. Will cam thrust plate leak keep good oil pressure? Oil is about 1500 miles as well. Was quiet for a while until this trip.

I would start bychecking grounds. With that many codes it seems electrical .
