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.

My vehicle makes noises when i accelerate


98% sure you have an axle problem. Might be wheel bearings depending on the sound. Bad axles will make a loud clicking noise, (click click click in rapid succession, espically while turning or under accleration) while wheel bearings will make a growling sounds.

I have a 2006 Honda Element that has always made a clicking noise in the rear every time I turn sharply (into a parking stall for example). Also there is a loud whirring sound that is also present that...


Axles usually make noise when any type of load is placed on them whether it be from turning or accelerating. I know that my daughters went bad just the other day. It was making a horrible clicking noise left rear.

My 2000 passat just started making a loud noise when i accelerate and it seems like its moving slower in acceleration and reving higher


my good friend I believe the solution I give might be not good for you as to what you state It sounds that you are loosing your automatic gear box. Have you ever changed the oil & filter of your Gear box? If not that was the reason.

Knocking noise from tires when accelerating


The noise may be your driveshaft ujoint going bad making the noise when you speed up,turn your driveshaft back and fourth by hand and see if it makes any noise. Jim Riley said that.
