the other day it was very hot and i was driving my car to a shop to get some things fix and tuned. the stock temp guage was a little high but after awhile it was smoking and i heard like a bang sound then right after i hear clicking it sounded like it came from clutch but after the car turned off i heard it from inside then engine. well i was driving to a stoplight and it kept want to turn off on me but i didnt let it i kept the revs up, then a stop light later in the middle of the intersection the car went dead i tried to pop start it with the clutch but it didnt work, so i had to cruise my way as far as i can to the nearest parking place, i made it to a rite aid but i had to push it a little. when i popped the hood it seems like something was burning either oil or coolant. the side of the head is all brownish like burnt and when i took of the spark plug cover i there is like oil or coolant stains also on top of the coils, like it was a liquid and formed into a dried clog of something, i dont know what happen but i need to fix it asap so if any1 knows what might happen please lmk. also if need more info lmk. i will add pics tom but here a video of the clicking. i hear it while its on its louder but when the car is off i still hear it.
