Hello! I have my spare (the original engine) on the engine stand being rebuilt, and have to have a look at the right engine bank of the engine installed in the car. I have what basically seems to be a dead cylinder. My question is...Is it at all possible to remove a cylinder head from an engine while it is still installed in the car? I do not have the space for two engines in my garage, plus two 911s. Any inventive and adventurous ideas or advice are welcome. Thanks.
