In my search for a solution to a few issues with my 1975 450SEL
Cutting out on full steering lock at low revs
Cutting out under heavy braking
Spluttering under acceleration up steep hills
It has been suggested to me that an injector service may help

Any suggestions as to what this costs ???
As despite owning 5 450SELs over the past 15 - 20 years ( yes I like them)
I have never had an injector service done

Is it a big job ?
Rough cost estimate ?

Years ago I had a triumph 2500 PI a fellow called Sadgrove up Pymble way
Serviced the injectors for the pricely sum of $12 ea ..
Now that would be nice ....

Contact Ken Airs in Melbourne for a quote on servicing or replacement. Note that even new injectors should be tested before installation....

You can also try Styria in Sydney on 0428-50-1800 ;) Some say that they can be cleaned ultrasonically - I am talking about K-Jet injectors. They are only about $55.00 each times eight (new ones), and one mustn't forget the nylon sealing pads which are a small extra. Removal and replacement are an extra at several hours. Again, this work has already been covered in other posts on TK. Regards Styria

I'd be checking your fuel supply before spending too much. Pull out the sender under the first aid kit and have a critical look inside with a torch (not a cigarette lighter)!! :eek: If there's anything floating around, or if there's sediment in the tank pull it out and have it cleaned. Replace any old hoses along with the filter. Consider flushing out the fuel lines with the tank out. Check the screen in the fuel divider/distributor isn't blocked.

Once that's all done you can remove the injectors after ensuring there's no contaminents around the seals with an air gun (you could also steam clean the engine first). Block up the open holes in the manifold with something that can easily be removed.

Consider carefully bending the injector ends of the feed pipes upwards a little and re-connecting the injectors so they still point downwards. With trays underneath all the injectors (and extinguishers handy) you could bridge the fuel pump relay terminals and check the spray patterns. Press down on the air flap slowly to check a range of fuel demands. If they're not clearly defined neat patterns, or there's dribbling, that's your problem....
