Hyundai / Kia 2.4L GDI Engine - How To Oil Pump Refurbish & Clean

This refurb / clean up video can be performed on any 2.4L Hyundai / Kia GDI engine with the dual balance shaft oil pump assembly. When doing a partial or complete engine rebuild, you may notice your oil pump sprocket appears seized or very difficult to turn. The pump may still be serviceable after a good cleaning in lieu of replacement with a expensive new one (around $800 at the dealership). Disassembling and cleaning up the pump internals can bring it back to good operational condition. I've rebuilt 8 of these Hyundai / Kia 2.4 GDI engines due to spun / disintegrated / worn connecting rod bearings as well as worn or stuck pistons rings. Metallic debris from these worn engine parts can work their way into the pump and accumulate at pump balance shaft holes and journal bearing surfaces.
