Eric,
two lessons out of this.
1. It's the little things that you forget that will get you at the end. I don't know what system you used to manage all the bits and pieces during the teardown but the so called "pile on the floor" method might have just claimed another victim.


In the age of digital photography its so easy to document every step and every nut and bolt taken off, and plastic ice cream containers make great temporary storage. I was caught once when a bolt was lost in the head - at least yours didn't make a noise like someone firing a machine gun in the engine bay which then exploded.

2. Essdub comes from South Australia. Wait a few days he won't remember anything about this.


It comes from drinking Southwark the local beer, or is that just a nickname for the Adelaide tap water? I lived at Klemzig for a few years so I know.


More seriously its a great example of how the MR2 Forum works and top marks to Essdub and others for helping out.

Okay so the mystery is solved! turns out it was the C clip that was missing. just checked it out and it works great now!
Also rotated that block, one side was a bit worn down so the shifting feels better
Thanks everyone!
So, what prize should I get Essdub? :P
