Multiple engine trouble codes?

Hi this issue is about this codes I'm curious why are this coming after doing this I'll tell you tell full story The story is it was running absolutely fine no timing issue just common oil Leaks due to the oil leaked on the alternator and it got malfunctioned some mechanic came and repaired the alternator but then what he did don't know the car was taking self but not starting he opened the Valve covers of both sides and removed some parts near camshaft area and timing then reinstalled it and reinstalled it after that engine power reduced fault code came and but by clearing the fault codes by scanner the car used to start absolutely fine no single noises of anything but again off it then try to start it again engine power reduced code come and it takes self but doesn't start until cleared the fault codes and the mechanics senior mechanic Said that the camshaft position sensor is faulty, give to other workshop they said engine was not taking compression told to change piston rings timing kit valve kit which was totally bogus and false when we towed it the we started the car by clearing the fault codes it come from basement by a steap incline till the tow truck by itself and after stopping it due to battery not charging from till now we haven't drive the car single time before stopping it its engine was like brand new so without driving it how it will happen after stopping it due to failed alternator, and it was having the enough power to cross that steep incline it climbed the steep incline without any hesitation just was having rough idle.
