There are a few things that could be the source but during the oil change, why wasn't any diagnosis done to confirm the problem?
1. Crankshaft pulley, if anything goes wrong with it, the damages might be costly.
2. Alternator bearings,
3. Water pump.
4. Power steering pump.
5. AC compressor or clutch bearings, idler bearing.
6. Timing belt tensioner bearing.
