Power loss, questionable mechanics.. WTF?

[green536@hotmail.com (Chris DeLong)]

WEll, AFA the crank pulley being on wrong I suppose anything is possible. 
You would really have to try hard to get it on wrong. Not to mention that it 
would wobble like a motherfucker because of the locating dimple.

The fly wheel bolts are not offset. So If you dont pay attention to the 
dowels when you put it on it will bolt right up and force the dowels through 
the edge of the PP. Also some aftermarket flywheels dont come with an index 
mark. This has to be added. Obviously not every one knows what to do there. 
It is way easier to put the flywheel on wrong than it is to put the crank 
pulley on wrong. And I have never seen a factory flywheel indexed 
incorrectly. This however doesnt mean that someone cant add another mark 
after they put the flywheel on wrong because they didnt want to taek the 
tranny out again.
