I bought this accord 5 months ago with only 93k. I changed the front
engine mount since it caused vibration at idling. I also changed timing
belt, water pump and all three drive belts 1 month ago. Now the car
runs fine although at idling there is still some vibration. Since it's
much better than before I replaced the front engine mount, it dosent'
bother me too much.

Today when I topped off the ps oil while the car idling, I niticed the
crankshaft pulley (and the other pulley? seems like there are two
pulleys there) has some vibration, while the other two pulleys above
have no vibration at all. IS THIS NORMAL?do all crankshat pulleys have
some vibration when the car idling? I am afraid the honda dealer
screwed something while they did the water pump job.

I searched this board, sb said there is some seal between these two
pulleys, when it's broken, the crankshaft could come off. I hope that's
not the problem I am having right now.

ANY INPUT is WELCOME!

Balance shaft is out of time, I'll bet.

Thanks for the input, I'll ask somebody to check the balance shaft.

Do I need to replace it? or is it going to be OK for several years? I
am almost broke after I did all the jobs I mentioned before.

The balance shaft is fine. It's the BELT that is possibly off one tooth.
It's replaced at the same time as the timing belt (or ought to be,
anyway...).

Make sure your nuts and bolts are all tightened properly everwhere...I
had no problem with mine until my crank pulley broke out of nowhere
from my mechanic not tightening the nuts/bolts after changing my belts.
I mean, it literally broke at midnight going 50 mph. Scary.
Apparently, since the nuts/bolts weren't tightened properly, it
vibritated it self off.
