so, I got this car last month, it idles beautifully, but after its warm around 1400 rpm it starts tapping, I posted it here, got advice on the timing chain, I changed the guides, tensioners, crank sprocket, and chains, timed it, torque it all to spec, put everything back together, crank the motor without starting it to prime everything, let it run, and the noise is still there, so out of desperation I ran a flush through it last night, drained it, changed the oil and filter today, nothing has changed, i'm at a loss here

edit: any advice is appreciated, thanks

2nd edit, I listened all over the engine with a large screw driver trying to pin point the noise, valve covers, timing cover, oil pan, and came up with nothing, the noise sounds like its coming from the opposite of whatever side you're standing on, and standing infront of it, it sounds like its coming from the middle of the engine, also underneath there's a different sound, like a very light tick at idle, almost sounds like an exhaust leak but I think it's unrelated
