I recently had my timing belt changed on a 2001 Type R DC2, now since the change, the sound the car makes is not like what it used to sound like before the belt was changed.
It does not idle rough, hasn't lost any power when it hits vtech and in general, does not ping, does not back fire.
could this be due to the new belt that was installed that has made sound more differently.
Could the timing belt be off by one or two teeth?
and could this damage the engine?

 

vtech? ok on a serious note if the timing belt was off a tooth or 2 you would notice a decrease in power. And more then likely bad MPG. What kind of sound is it making?

 

okay i'm not sure what you mean by MPG?

But the sound that it makes when your in any gear and you start to rev the car past 3 thousand rpm it sounds like a spool like sound, its really hard to explain but could it have something to do with tension that was applied when changing the timing belt.?

 

its prob in your head
recheck timing

 

A spool sound? You mean the intake whistle? It's normal and very common.

 

MPG = miles per gallon.

Agree with b serious. The intake whistle is very common.

 

If either of these belt guides (front and/or rear) were installed backwards, the sharp edge of the guide will be digging into the sides of the belt as it enters and exits the pulley. Notice how the picture shows which way they get installed. This will definitely make a sound. Kinda like a quiet version of driving in reverse w/ a manual trans as you rev.

Also maybe an aftermarket belt was installed that is slightly wider causing it to rub on the belt guides. Those would be the first two things I would check...

 

^^^ Nice post and info for future reference.

 

Ive been a tooth off before and it barely ran, it was undrivable.

 

don't you love that, dies at stop signs, feels like **** etc

 

Yeah, didn't even consider driving it. Idled like those old hot rods with big cams. Lucky you can get to the tensioner and fix it without having to tear it all apart.

 

@ 94eg! Great Post Thanks!
that makes perfect sense and yes it was a aftermarket belt that was installed and it does sound like you are in reverse when the revs are going. The belt was exactly the same size as the original belt, it was not wider. so it may have been that the mechanic didn't place the concave guides back correctly. but if this isn't looked at what issues could it possibly cause.? any ideas?

 

Bad, require a new engine type issues if it wears enough and the belt snaps.

 

had very similar problem with mine after timing belt change, turned out timing belt was too tight. wasn't properly tentioned.

 

timing belt is a lil tight but shouldnt hurt you.
