Question 83 SC fuel injector inspection and performance

83sc. Checking spray pattern and seals on injectors with 120k miles. Injector seal (green) replaced on injector.

Took out #2 and the "socket or Offically the INJECTOR SLEEVE" came out with the injector. I appears that there is a rubber O ring seal at the top of the socket, but it is so hardened that it appears to be plastic. [B]Answer: o ring at top hardens and needs to be replaced. If the Injector Sleeve came out with Injector it should be replaced as well. Not expensive.[/B]

Is there an o ring on the injector socket, (also heard it called a bung, but it officially a Injector Sleeve if you go to look for one) that should also be replaced (knife points to suspected o ring) ? find it here Porsche 911 & Turbo CIS Fuel Injection - Page 5 http://www.pelicanparts.com/cgi-bin/smart/more_info.cgi?pn=911-110-886-03-M260&catalog_description=Injector%20Sleeve%2C%20%20%39% 31%31%20%28%31%39%37%34%2D%38%33%29%20

How to best remove the sleeve if if doesn't come out with the injector?

Should the injector MIST or spray (as a faucet sprayer)? ANSWER:a v shaped mist

If it sprays (as in my case) will serious dose of sea foam clean these up?

Danke.
