Hello all, I ended up doing this diy and this thread really scared me and had me second guessing my work.

When I tried to install the crank pulley (the first time) it was such a tight fit that when I attempted to re-position the perrin crank pulley the metal o ring popped out along with it.

I got scared. This thread immediately started flooding my mind. After panicking a bit, I found that with the o-ring off I was able to knock the perrin pulley on with my gloved fist. But because the pulley was on I wasn't able to see how the o ring was sitting in the crank case.

By slightly twisting the crank pulley it locked into position as well as sliding down a bit. When it is on properly I believe it will NOT rotate. IF you are able to rotate it is not sitting correctly. I found that spinning it back in place was not very difficult at all despite some of the earlier posts here. All you have to do is take a picture inside the crank case if you forgot which way the key was pointing and then put the crank pulley with the key pointed in that direction. After that twist until the crank pulley slides down a bit and locks into place.

But because of this thread I started second guessing my work and I took the pulley off to inspect how the o-ring was sitting. Here's my picture of the re-positioned o ring. https://plus.google.com/photos/10900...PCsg8rEiuv1gwE

I looked at the back and there was no damage. After removing the lightweight pulley and re-installing it seems to spin a little smoother than stock. So I think as long as you check to make sure that the crank pulley is not able to spin and you have the key pointed in the correct direction you will be fine. I hope this reduces some people's fears. I did get a CEL after the 2nd install but I think this post http://www.ft86club.com/forums/showthread.php?t=27900 is what happened >> "It was the intake. I didn't push it in far enough when reconnecting it to the inlet at the front of the engine bay where it connects in front of the airbox." I'll go take the car to auto zone to check the cel code but the pulley is spinning fine. BTW this mod was the most noticeable upgrade I've made so far. Highly recommend it. I haven't notice any increase in stalling after the upgrade and love how revs are less labored.

EDIT: Okay the next day I started the car and I was relieved to find that the CEL was gone. I did not disconnect the battery. I took it to autozone and they told me CA laws prohibit them from reading the CEL code for me. They did tell me that spinning the crank may have set the CEL.
