    maybe what you hear is the butterflies in the intake opening, and not vtec. i'm pretty sure vtec will not engage if there is a problem with the vtec pressure switch/system.

    put a vtec light in first off, to know for sure if it is working or not...

    and is the motor warm when you try pushing it for vtec?

    Here are a few things to do. One make sure your oil is full. Reset the ecu take out the fuse for a solid minute. I would suggest takeing the silinod off. Make sure the screen is not cloged up with old oil and shit. You can also take it apart if you see there is a lot of deposit on the valve break cleaner will help you out and auto tranny fluid will really clean it up. If you have a bad speed sensor or a loose sensor cable vtec will not work. If it is a gsr make sure the butterfly valves are working check the vacum lines. Make sure you ecu is grounded well not just flopping around. You could also just have a bad oil pressure sending unit.

    it sounds like there is a "slow" or distorted bearing in your tranny.
