OK, been making a little headway on removing the old squirters ("little" being the operative word...). I've been following the procedure outlined in this thread:
http://forums.pelicanparts.com/911-engine-rebuilding-forum/643424-anybody-here-ever-replaced-piston-squirters.html by fastfredracing.
A quick summary:
1. drill out top of existing squirter w/5/32" drill
2. remove spring & ball
3. drill through bottom of squirter w/5/32" drill
4. tap squirter w/5mm tap
5. carefully dremmel staked case marks at top of squirter to ease extraction
5. fabricate slide hammer w/5mm bolt end attachment, which gets screwed into tapped existing squirter
6. gently heat case area around squirter
7. use slide hammer to extract existing squirter remains
8. be happy
I'm stuck at #7. Or rather the squirters are stuck in the case & won't budge with semi-gentle tapping w/the slide hammer. I'm afraid I will strip the threads out of the squirter as they are really soft aluminum and the 5mm tap is barely big enough to cut threads into it except at the bottom...
Anyone have suggestions for another extraction method? More heat? Bigger tap & bolt?
Thanks,
Tom
