Without much detail as to what was done prior, anything we can offer here will be limited. That said, there are a few things you can do to get an idea. The first thing I have always done on Hyundai/Kia and FCA/Stallantis engines is I will take a few spark plugs out and check for oil consumption; granted the FCA/Stallantis vehicles that don't have Fiat engines aren't as prone to it (see: Jeep Renegade for something with the problematic Fiat engines), but it happens on these due to some cost-cutting on the Stallantis era FCA vehicles. You do not need a fancy borescope camera -- [https://www.harborfreight.com/digital-inspection-camera-61839.html|something like this will do the job|new_window=true].

The other things you want to check are the valve cover gasket and the oil pan gasket. The one I usually check first is the one under the engine since it's plain as day once you take the beauty cover off. For the lower pan, jack the car up and check around the pan. The oil pan one is pretty easy, and you can usually get replacement gaskets for $10-20. Sometimes these use high temp gasket maker; in which case, you need the[https://www.summitracing.com/parts/ptx-82180?srsltid=AfmBOop9byjoQJk_waMsVAof0RFFlvxhjcl90_o0_6V1U5urGa10po0wBU8|high temp variant|new_window=true].

You also want to check the valve cover gasket and the oil pan gasket. The one I usually check first is under the engine bay since it's plain as day once you take the beauty cover off. For the lower pan, jack the car up and check around the pan. The oil pan one is pretty easy, and you can usually get replacement gaskets for $10-20.
