The noise isn‘t like wow, thats gonna wake up the neighbors but, it‘s noticable. and I just bought it, I hope it can be fixed.
Not necessarily. The check engine light primarily monitors emission system functions.
not necessarily. something as serious as that would just seize the engine. if the engine ran too long w/o oil it probably did all the damage that is internal not an easy fix. pistons could get stuck in the bore so on.
A check engine light usually means one of two things - you have a problem with your emission system or there is a problem with the engine computer, sometimes major engine failures such as blown engine rods, overheating or running with no oil will not trigger the check engine light.
