the motor is stock, i just finished the swap maybe a few weeks ago, been working on getting the finishing bugs out of it.. and putting it all back together, ive literally drove the car for maybe a few hours at max of driving.. and it started making this sound one day when i was checking over the car before leaving work.. it ran fine for a day or two before i caught this. it does need some tune up things, which i was getting to this week before this noise appeared. its my shitty iphone quality
