For 1/2 quarter low, oil is going somewhere./Does the enine smoke in the morning?
Add oil and see if the noise stops.
If the noise still there ticking.
According to what you said earlier that the ticking noise increase in frequency when you accelerate mean technically that ticking noise occures at the same rate as cranckshaft rotation can be cause by piston slap, lose piston pins, worn connecting rod bearing or worn main bearing.
Open the oil filer cap and listen to the opening.
Listen at each intake and exhaust manifold runner using a stethoscope. Place the stethoscope on the fastener holding the valve cover.
Disable one cylinder at the time, let me know if the noise stops.
Check everything mentioned and keep me updated
