I have had my oil light come on and sometimes off and a oil leak somewhere. So i went to change my oil sending unit and noticed it wasnt leaking anywhere from there but also noticed ALL of my oil pan bolts were really loose. To where i could wiggle them just by touch. So i tightened them all. I am asking is it possible that that could be the reason my oil light is on? Thanks all

 

Your low on oil or your oil pump is failing, I suggest torqueing the oil pan bolts down to spec and fill up with oil and check for any major leaks.
