Is that the noise you mean? Rough and loud? Yeah, it makes you wonder if the timing is off by a tooth or two, doesn't it?
There may be a viewing/access plug on the camshaft sprocket cover to see the cam sprocket timing mark, when the crankshaft is turned to TDC, or 0 degrees. If no plug or access to see the cam sprocket, it might be wise to re-check the timing. Is there any difficulty in starting the engine? Or does it seem to run warmer than normal? Was the belt tension set correctly? Just a few things to consider, good luck.

Loud noise when I turn the car on or accelerate or decelerate. Sounds hallow. Slight rough idle. Warmer the car is more noise. What is the problem, please? 2006 Hyundai Tucson V-6, 60,000 miles.
Main possibilities to check are...
Exhaust leak or mechanical exhaust contact.
Induction roar.
Noisy bearing in the auxiliary belt/timing belt area.

Engine making loud noise when running I removed the serpentine belt and stop?
Turn all the pulleys by hand. Chances are you will be able to tell if there are bad bearings in cone of the following: Power steering pump, alternator, idler pulley, A/C compressor. The one that is failing will probably feel rough when you turn it or have a lot of play in it.

Mitsubishi mighty max 3.0 v8 loud noise coming from the fan area
If the fan is attached to the water pump tahe hold of a blade and try back and forward towards the motor. If there is movement there it will be either a fan hub failing or a water pump bearing. Second check remove the fan belt and check for noise.( idle engine for short period of time) If it is gone confirm pump by spinning any adjuster pulleys and check for noise or rough movement

Loud chirping noise when acceleration pedal is
There is a TSB (Technical Service Bulletin) for this problem:

Engine - Accessory Drive Belt Noise Diagnostics/Tool
08-06-01-008 03/27/2008
This particular vehicle had an issue with pulley alignment, particularly the power steering pulley. Take a look at the shaft the pulley is pressed onto. If the end of the shaft isnt flush with the pulley, it is out of line and will cause a squeal.

It is recommended that you discuss this TSB with your dealer (not local mechanic).

I hope this helps.

2002 Saturn Vue V6 AWD sounds like an F1 car when i drive it. Very loud constant noise. Checked trans fluid and it was fine.
I have a 2002 saturn vue. Same thing..sounded like a jet engine ...loud humming as I accelerated . It got increasingly worse. It turned out to be the front wheel bearings. Replace them, now the noise is half as loud...have to do the rears also! 93,000 miles on it. Also, don't forget to replace the timing belt. It it goes too long and breaks, it will trash the engine...

Loud rattling / buzzing noise from engine when cold not seconday air pump or air valve as already replaced.Timing belt,water pump and aux pullies all checked and ok.The colder the weather the louder the...
If the rattling changes with the revs of the engine, it might be that the valve compensators are either worn or not getting enough lubrication. 20V engines have quite small oil passages travelling to the head. They tend to clog up with gunk if the oil change is not frequent enough.

2004 Ford Taurus V6 noise underhood appears to be belt
Sounds like a bad idler pulley,or belt tensioner. Most likely not water pump since the check engine light is not on. Altho it couold be the water pump and for some reason (bad sensor, burnt out light) the check engine isnt coming on. Either way it would be best to have it looked at.

Engine noise on area of pulleys and sometimes engine tries to sto
Don't know if this helps. Had squeel in belt area. Occasionally engine would stop when squeel got loud and sometimes engine would try to quit while going at various speeds. Found tensioner pulley was bad and changed it. Still squeeled and engine would stop when squeel got loud. This time while sitting in yard. Further checking found binding in power steering pump. Will be putting on new one tomorrow. Hope it works. Will update.
