I bought this accord 5 months ago with only 93k. I changed the front\nengine mount since it caused vibration at idling. I also changed timing\nbelt, water pump and all three drive belts 1 month ago. Now the car\nruns fine although at idling there is still some vibration. Since it's\nmuch better than before I replaced the front engine mount, it dosent'\nbother me too much.\n\nToday when I topped off the ps oil while the car idling, I niticed the\ncrankshaft pulley (and the other pulley? seems like there are two\npulleys there) has some vibration, while the other two pulleys above\nhave no vibration at all. IS THIS NORMAL?do all crankshat pulleys have\nsome vibration when the car idling? I am afraid the honda dealer\nscrewed something while they did the water pump job.\n\nI searched this board, sb said there is some seal between these two\npulleys, when it's broken, the crankshaft could come off. I hope that's\nnot the problem I am having right now.\n\nANY INPUT is WELCOME!
