I've also seen several 2.2L with hydraulic lifters come in with a loud tapping noise and after removing the valve cover and rocker arm assembly, I've found a small piece of plastic or silicone blocking the oil access port on the underside of the rocker assy. Remove the blockage, pump up the soft lifters (hold in the small one-way valve with a pick while pumping up the lifter while immersed in oil) and reinstall. The noise should be gone...HTH
