yesterday i had no oil in my engine and what cause me to check is because the engine was making a kinda like puffing air/fluttering sound (almost like a sound as if there was an exhaust leak, but there isnt), i put oil in but overfilled it almost by 3L, it was still making that sound..and also before and after i filled it up, the engine had no power and was bogging alot, until

ok update, just went out to the car and cylinder 1 spark plus was drenched in oil. i will be getting 2 new spark plugs. you guys think the air puffing sound was the engine misfiring? or a blown piston ring, because i took out 3L of oil and still was above the max. fill line on the dipstick. major overfilling can cause major damage or new spark plugs and i shall be fine? its just soo weird because when the motor had NO oil, it was still making that puffing air sound, alittle but later in the rpm's (around 5k+) and when i did put oil, even though it was too much oil, it still is making that puffing air sound. i dont know what an engine misfiring sounds

 

pull your plugs and do a compression test (kit $15)
if its all even around 200s, replace ALL the plugs and drive it around and do a proper complete oil change
