Luis5.3

So i don’t have any more ideas. My Chevy 5.3l is ticking when warm with 40psi oil pressure…
Most time passenger side but some time on both…

following parts are new (stock 5.3l from 2002)
Without a change

lifter with trays(gm trays)
Pushrods
rockerarms
oil pump oring
exhaust manifold gaskets and manifold itself
sparkplugs and wires

i attached a video

I don't hear anything in that video that would concern me. LS Engines are not the quietest running things ever, that's for sure.

but this ticking tapping is only on that side not on the other side most of the time 🤨

The only thing I would check is that all of the rocker arms still have all of their needle bearings. If a few have fallen out of one, it could start getting noisy.

they are new and it was the same noise before
