Could anyone on this list tell me if these are the correct fuel injectors for the ’75 Opel Ascona with the Bosch EFI? Thanks!

They use brass valve guides up there, Keith? Learn something new every day . . .Keith Wilford said:. . . hardened valve inserts and brass valve guides . . .
Thanks Gary, I looked at the throttle body, but the shaft seemed reasonably tight. But maybe I'll pull it apart and have a better look. Do you know what the allowable clearance is? Hey, can you post the bushing part number and dimensions? I know you used the old TB bushing, but do you know if Bosch or even jobber bushings are available off the shelf? Were both sides the same dimensions? I was going to take my shaft roller down to a local bearing supply store, so perhaps I will take the TB bushings down as wellGary said:Throttle Body Repair --------------------------------------------------------------------------------
Had a problem with the Wagon's engine running lean. Sprayed some carb cleaner around the throttle plate linkage and the car stalled. Checked a little further and noticed some side play in the shaft. I picked up a spare TB that was pretty corroded but had no play. Took it apart and found there was a pressed in bushing on each side of the throttle body. Using a punch from a hole transfer set, I pushed the bushing out. Did the same to the worn TB and swapped out the bushings. Vacuum leak fixed.
The bushing was worn down ~.008 on one side. I'll post the bushing part number and dimensions tomorrow. (actually later today)
So, that would be "BRONZE" valve guides? Thanks for the "correction" Ottotekenaar said:They use brass valve guides up there, Keith? Learn something new every day . . .
Keith - I have part numbers from Python Injection and Standard for the injector seal kits. I'll post them for you. The Python kit comes with the plastic tips for the injectors and the tiny little filter screen on the inlet side of each injector.kwilford said:(and I believe that they are very common, since all Bosch MPI injectors of this type uses the same O-rings)

What is the chance of you doing a pictoral how to like Rally Bob's "How to do a Big Valve head" or Opeldean's carb rebuild DVD??
Thanks Scott. I made my own gaskets for the injector plates, using the olds ones as a template. The throttle body gaskets were still in good shape, so I re-used themSportwagon75 said:By the way...I noticed from your photos that you've disassembled the T/B for cleaning. Do you know of a source for all the other gaskets in the throttle body and the plastic injector plates, etc. Does OGTS have these F/I gaskets? I have several gasket head sets that are "supposed" to include the 75 model year but never seem to have all the F/I specific gaskets.
