A faulty oil pump can, surprisingly quickly, trash a perfectly good engine! The safest option is to either fit a complete new unit, or take the less expensive route of refurbishing the old pump and ancillary items with as many new components required.
This part and perhaps some of those listed below may be of interest.
Check our online schematic to ascertain which parts you required to complete the oil pump assembly refurbishment. Add as many items to the same shopping cart as you wish, new filter, gaskets, seals and fasteners for example, and still only pay the same single fixed price shipping cost. Please be aware that this component may have other applications in the Honda model range.
