This may be the issue. Although it does not explain why the noise returned all of a sudden.
When you hone the bore you actually increase the clearance between the liffter and the the cylinder in the head that holds the lifter in place. The oil gets pushed in from the side of the lifter where it enters the lifter. It relies on the pressure caused by the clearance to allow oil to enter the lifter. The pressure drops however if the clearance is too much causing the lifter not to get enough oil and thus become noisy.
