I have my Bosch injectors out and I see that one of them at least has a cracked tip. The yellow plastic cylinder that sticks in the intake has a crack. I don't know if this affects the function of the injector.
Also all the injectors have some wear at this yellow tip cyclinder. I guess it is from movement in the rubber sleeve.
Someone recommended that I should have them tested and cleaned which costs about $ 17 plus a new hose = $ 21 per injector.
But... there is still no guaranty that the injectors are good. If not it might me more expensive.

There are alterntive reman injectors out for only a little more...like $ 25
GB REMANUFACTURING Part # 85213101?

I also heard that some Nissan injectors would fit right in the MB.
Nissan or Datsun Z 280 turbo injectors FJ23?

So my question is: what would you do?
