My Acura TL 2007 is making this noise if anyone can help out with it

 

gotta dive into it and figure out where the noise is coming from...take off the plastic cover.
then isolate where the noise is coming from...back, front, left or right?

 

Most people have been telling me i need a new engine the car only has 150k miles i've changed the belt last month

 

the sound is coming from like left and middle

 

Who changed the belt?
have them look at their work.

Most people have no clue until they start to dive into the engine...
so, it would be best to get your mechanic who did the timing belt last month to check it out

 

have you checked the engine oil? is it at the full mark?

but if it were me; i'd go back to whoever did the timing belt and say you fucked up my engine.

 

the oil has 40% left in it so i'm not sure if it's that or my transmission as well

 

What does 40% mean? Have you checked the dipstick to see what the oil level is?

 

yeah, instead of guessing... Take the car to a mechanic.
none of our troubleshooting tips will help you because your knowledge of car mechanics is slim.
That's not a knock on you. It's just very hard to walk you through if you don't have basic knowledge.

Take the car to a mechanic.

 

Sounds a bit like your TB tensioner is rattling. Take it to your mechanic and have them investigate. Was this changed with your timing belt last month?

 

serpentine belt was changed but nothing else i noticed a polly was lose so tighten it up but i've been figuring it's that

 

again, not a knock on you...
but it doesnt give me confidence that you know how to diagnose/troubleshoot whatever may be going on with your car...

you gotta take it in...take it to a mechanic and ask what the noise is. they will dive in and figure it out for you

 

sounds like your timing belt tensioner or a worn out camshaft. as stated before you have to have a decent amount of mechanical knowledge for us to try and help. you would be better off taking it to same mechanic or another reputable mechanic. timing belt tensioners should be replaced when you replace the timing belt, and the mechanic could have, but, quality matters. when parts cost a quarter of the price than the OE you know you are only getting a quarter of the quality
