Basically with the engine running you can hear a damn awful noise of something spinning loose under the bonnet. After closer inspection it can be seen that the crank / pulley are vibrating horizontally as they rotate. The noise and vibration is becoming progressively worse.
So what i would like to know is:
how much driving time do i have left before it lets go?
Is it a big end bearing? If not what is it?
Will i require a new 6M crank?
How easy is it to fix these things yourself?
How much am i looking at for a bottom end rebuild?
