Loud roar after timing belt replacement

[somick]

It is hard to describe a sound but that what I hear: a very loud roaring sound that develops after 2000 rpm. Sometimes it sounds like a tractor trailer.

It all started after the timing belt replacement.

I know I am guilty: I bought OEM timing belt but stop short on buying OEM balancer belt. I bought the cheapest for 10 dollars vs. dealer’s 25. May it cause the noise?

I did not torque the pulley right (did not have torque wrench at the time).

When I look at the pulley it looks like it wobbles a little. No more than 1mm.
So I rented a torque wrench from Autozone and planning to torque the pulley to the correct torque this weekend (181 ft/lb).

Will it help me to get rid of noise or should I live with it till the next belt replacement?

99 Accord LX with 74,000 miles. The car is 96 month old and the maintenance schedule calls for timing belt replacement at 84 months.

Any ideas or suggestions are greatly appreciated!

Well, well...

I guess I will ask this question at another forum.

Thanks for reading,

I am LAZY, LAZY, LAZY, LAZY!!!

I am ashamed of myself!

The balancer belt was installed 180 degrees off TDC. I most likely made uneven number of revolutions of the crankshaft and then installed the balancer belt.

Everything is fixed! Hopefully I did not ruin my engine.

On the good note: the second time it took me only 45 minutes to get to the belts. The experience matters!!!
I hope that somebody when searching will find this thread and will not make the same stupid mistake.

Thanks everybody for ideas and support. Thanks for the help!

If it is worse when cold the belt is loose, if so 15 minutes is all it takes to fix the problem.

Thanks, tim.
I probably did not expain it correctly in my last post:

When I installed the balancer belt I did not verify the marks and as a result it (the balancer belt) was installed wrong: 180 degrees off (up side down).

It is all fixed now. The car runs like a champ!

Thanks for your suggestion,
