CIS Injector Seal?
 

Hello Porsche People,
I recently ordered (6) CIS fuel injector o-ring seals for my 1991 3.3L Turbo. I used the Pelican Parts catalog view and the P/N shown was 900-123-144-30. This crossed to an aluminum washer. Guess what I received? Yup, (6) aluminum washers.

I can't find any reference in this forum or the Turbo forum (mostly 930 folks) where the typical CIS injector o-ring seal was replaced by a flat aluminum washer. Do my injectors screw out instead of pulling out? There is nothing in the Bentley PEC about this, only a picture on page 153 of an injector with a fat o-ring on it.

Hey, maybe I have "special" injectors from a one-off 935 racing motor in my car, or half of a 917 flat 12 engine? Maybe I can sell these "billet aluminum racing washers" signed by Richard Attwood on ebay for $1000.00 ea? (or not)

Thanks,
Mark

Hi LUCITTM.On my European 1991 964 TURBO,the injectors are screwed on the engine with an aluminium washer.I don't know for American cars if it's the same but you can check easily how it's on your car.Good luck

Mark i replaced my o-rings and yes they are flat metal washers and the injectors do screw in and out.
