advice on engine overhaul or surplus ?

general overhaul. the oil filter did blow up while on NLEX then now it sounds like the bearing was shot. I've attached video for the sound now.

I've heard the clip and YES that is rod knock. It wont affect anything, idle, power, etc especially at this point. My advice, no matter how tempting it is. Don't drive or turn on the engine.

Sometimes, you can get away with just a simple rod bearing replacement with a simple/slight knock. If you continue to use it and wait to make the knock more audible, you could be looking at replacing the crankshaft, conrod and oil pump.

Have it trailered to Fronte in Banawe na lang. Once stop shop, mechanics are good and the sell Hyundai parts.

Good luck!
