    Sometimes at high speeds, or acceleration...basically higher RPM's, there is a really wierd sound coming from my engine area...sounds like a vibration of some sort...also, my starter sometimes makes that nasty grinding sound when I try to start it...could these be caused by a bent or out of balance flywheel? My flywheel is under warranty from my tranny rebuild, so it'll be free to replace if its bad, just wanted to know.

    You can pull off the dust cover and take a look at it. I had a cracked flexplate once, the engine made an RPM related ticking noise that went away while the engine was under load. After a while, the input seal to the transmission started leaking from the torque converter moving around.

    BTW, automatics have flexplates. Flywheels are for manual trans.

    I haven't heard of a bent flywheel or flexplate, but I've heard if cracked ones. If it's cracked it will stick under engine load.
