Whats wrong with my car?
 

My Maxima turns in and moves but doesn't go past 2000RPM. It makes this really loud sound which I feel is coming from the back side of the engine near the windshield. My brother was driving it and says he was going 65 down the highway and all of a sudden the noise came up. I took off the front valve cover and everything is moving properly. I cleaned the Idle Air Control Valve the other day so i'm thinking that that might have messed it up But I doubt it. Here's a YouTube video if my car engine and the sound that its making please watch this and give me some ideas of what you think is wrong with it. Thank you!

We cannot get the solution from that video so to identify you must go to a car care center. If the engine is giving the noise so it might have many issues.

ummm, time for a new vq buddy. sounds like the engine is half full of oil. check for codes, leaks, check fluid levels. that def does not sound good.

You have this posted in the wrong section but I would check the oil pressure. Heard something similar once before when I was in a 5th gen and had to pull over for same noise and oil pump was dead...

which would be a new vq essentially.

Well surprisingly if it wasn't driven like that for a long time, no the engine will still run like butter. I know its hard to believe but these VQ30 were bulletproof. He replaced the oil pump and it was fine.

What section should I post to I thought this was the right one. And yea my maxima is broken. I jacked up the car and saw that there were 2 little chips directly in the middle of under the engine and engine oil was leaking from there. I'm not sure if that's my engine blown or if its a part that is broken. The chips are right under the engine. Like if you jack up your Maxima and look under, you'll see this black long metal that goes from the front to the back of the engine it's next to the oil pan. On top of that is where the cracks are. Any ideas??

Also sorry for this nubish question but what exactly is a vq??

VQ30 is the engine.

From the fluid sub forum;
Your engine is blown up. The noise you here, and the hole in the engine that you are leaking oil from are both caused from a broken connecting rod. You need a replacement engine.
