Newly Installed Timing Belt Noise

I have a 1992 Accord Wagon, 2.2L engine, 189,000 miles, this is the second
time I have changed the timing belt. I had my local mechanic change the
timing belt and he also changed the water pump, crank and cam seals, fan
belts, and valve cover gasket.

After the work was completed, my engine sounds much louder and the tone of
the engine is lower than before. It sounds like someone has tried to soup up
my engine. I took it back to the mechanic and he thinks it sounds fine.

Should the engine sound different after the timing belt and water pump were
changed?

 

Is this a loud hum or whine?

Timing belt may be too tight. Common error.

 

Check the air filter housing, I had some work done once and after I got the
car it sounded like the muffler had fallen off.. turns out the air filter
housing wasn't completely clipped back together...

 

no. something is messed up.

 

I have a loud hum like a hole in the muffler. I also have a screeching sound
when I start the engine with my air conditioner on. When I turn it off it is
better, but sometimes is still there. The engine sounds tighter than it was
before. Thanks for all the responses.

 

<shakes head>

Why do I answer these posts?

 

nah, it's "why do they /ask/ these posts?".

 

OK. Loud Hum.
