Car knocks the more it you give it has the faster it knocks. This seems to be a rod, but I bought a knock sensor to rule it out. This is a friend's car and he said after hearing the noise he checked the oil and it was bone dry. When I arrived the oil was still low it needed two more quarts. I noticed metal flakes in the oil along with other dirt. What do you think. Again I believe it's the rod, which is common on the 2.4 quads.

If you see metal shavings in the oil, it is most likely a rod, especially if it was run low on oil. I wouldn't keep running it as you are just causing more damage with the metal shavings

Noises problem
1999 Pontiac Grand Am 4 cyl Front Wheel Drive Automatic

hello, i have a 99 grand am se, 2.4.. im a girl, dont know anything about my engine lol but i was driving it on the highway, i kno i was way over an oil change, and all of a sudden my car did not want to accl. at all and there was a extremely loud knocking noise. but it would still drive home as long as i accl. very very slowly and did go over like 30 mph or it would die out on me. the noise starts as soon as i start the car, and if i push on the gas and rev it up while its in park, the knock seems to go faster, can anyone tell me what this is? ive had ppl say a rod, lifter, timing chain? im a single mother and cant afford to take it to the shop, and i cant pay to fix it if i dont know whats wrong with it.. any ideas? please help me!!

Honestly, it sounds like a rod or main bearing in the engine. Let me know if you have other questions.
