Strange ticking or squeaking noise from engine

Hello,

My car has had a weird squeaking or ticking noise coming from the engine. When I looked into the bay, I noticed an oil leak, so I had it repaired.
(Turns out it was from housing gaskets, had both replaced, and oil change). After the repair, the squeak is still present. I have no idea what it could be coming from. Sounds like its coming from the front of the engine.

Pulley? Bearings? Alternator?

Maybe the belt, that leak was right above it.

Ditto - look for collateral damage from the oil leak. Belt, pulleys, AC compressor or alternator.

How many miles is on it and has the belt and tensioner been replaced yet?

I would remove the belt and spin each pulley separately to see if one wobbles front to back, makes a noise or vibration when you turn it or makes any sound. Without the tension from the belt it won’t sound the same. With the belt off, inspect it for any damage or residual oil. Also make sure the tensioner is not at the limit.
