2003 2.5L strange start up noise

[DiceOfSeven]

Hello, new here and I am curious about a sound my 2003 Nissan Altima makes when it starts. First off let me state that this is the 3rd engine in the car. 1st engine the catalytic converter was not changed and particles were sucked into the manifold and the car started burning massive amounts of oil. I determined we needed to replace the engine bought a 3000 dollar refurbished engine from Marshall engines located some where in Nebraska.

So we get the engine have a mechanic install it. Runs good then about 2 days into getting it back it makes a strange loud rattle on start up and it gets progressively worse. As 3 months rolls around, I was on my way to work when my engine started this loud banging I slowed down got to work called my father about it then went into work. I took it easy on the way home since it was a bad neighborhood where i was working and feared it would be broken into overnight. Loud banging continued all the way home. Talked to the mechanic and he spoke with the reps from Marshall Engines. Ends up someone assembled the "balance box" wrong so we had it replaced but by that time the damage was already done and there was a loud knock somewhere in the engine.

Again spoke to the engine people and sent us a new engine on them and paid the mechanic for there mess up. Well had it back for a week now and its making the same noise on start up. Is it safe to assume the balance box might be bad again? I posted some links to a few cell phone videos I have of it starting up and you can here the noise. Can anyone give any advice or know what the noise might be? My only concern is it will just get worse the longer I let it go like last time.

Sounds like no oil is getting to some parts. :/ Engine sounds effed to be honest. So it makes that noise while driving too. Does it pull hard when floored etc? Or does it seems powerless?

It sounds like something mechanical fur sure though. :/ Can you get a video of the engine with the hood popped and get someone else to start it? Might give us a better indication. While it's running move the camera around to different parts of the motor so we can hear sound from all angles.

Upload in better quality if at all possible.

It does not drag, from what that I can tell. It has plenty of power too, it will get to 75mph easily if I'm not paying attention. It just makes that noise on start it goes away after about a second or 2. It kinda sounds like a typewriter when its running like *tick tick tick tick* told its a typical four cylinder sound. It should be warm here tomorrow I will record some high quality audio and upload it for you.

could be the starter is not disengaging when the engine starts and is grinding.

[QR25DE]

Yep def could be the starter. Are you using the same starter that you used on the other engine?

[wade001]

im assuming he did. i doubt 2 different engines would have the exact same thing. i think its either the starter or the toothed wheel it engages has some missing teeth, but i say the first of the 2 is most likely.

Also have an03 altima 2.5l and had engine just replaced about 500 miles ago and its doin the same noise at start up they told me to use the Nissan oil filter and that it would help but I dont think it did it still rattles after warming up and letting sit for a while. Have you figure out what it is? Help plz
