OK, so what's the trick for removing the circlips that hold the piston wrist pins in? I spent about an hour looking for different ways to get those circlips, and could not figure it out. ![banghead](https://rennlist.com/forums/graemlins/banghead.gif)

My friend and I just did this the other day. You have to locate the break in the circlip( very hard to see). Shine a light in there. Use a curved pick to pry the circlip out of the groove, Then take a very small pliers and finish pulling the clip out. Watch your eyes, since the clip may fly out.

I'm the 'friend.' I have a high-quality (Mac Tools) sharp right-angle pick (4" overall length, sharp tip and nice large handle that gives leverage to the tip) that I used to get caught under the clip end. Then, pry the end out of the groove. It'll stay there while you use your Sears parrot-nose ignition pliers, that all decent Porsche techs should have, to pull it out. Pull in a way that shrinks the circumference of the clip.
Then I used the shaft from my small slide hammer, another useful tool, with a 3/8" nut on the end to place through the piston pin and pull it out. The nut fits inside the circlip still left on the other end so you only need to remove one clip to pull the pin.

Toby: Welcome back, haven't seen a post from you in too long! Dental picks, as mentioned above, are your friend. I know that high quality ones are available from SnapOn and Mac, not sure about other tool sources. Use a 45 or 90 degree pick to work one end of the clip out of its groove, it's easy from that point. Congratulations, you've discovered about the only part of a 911 engine repair that can make you bleed! By the way, an earlier problem that we discussed has been satisfactorily solved, if you need details please e-mail me. Cheers!
