    Default Re: A 450 CDI restoration

    So work on this has stalled because of the other 450 that I have being a model example of how to fail an emissions test. However, I've not forgotten about this one.

    I've managed to source a new exhaust and a turbocharger (winging its way from Germany) along with a fitting kit for this so with any luck, something major will be happening in the next couple of weeks with this and I can finally get it out of the garage. The EGR valve still needs working on but once the snapped stud is out, then that is the final piece of the puzzle to getting it running.

    For reference, the torque figures are:

    Turbo manifold to block: 23nm
    Exhaust to Turbo manifold: 30nm
    Exhaust bracket to gearbox: 23nm

    So the EGR valve in the CDi appears to be OK but the housing around it is still screwed with the broken bolt.

    Luckily, Ball and Brown in Southport had one for sale on the off chance with a relatively new cartridge in it so I decided to get that and then I can spend a little time cleaning up the original valve and getting the broken bolt out. In short, this completes all the parts procurement to get the engine running, which is:
    • New (to me) EGR valve
    • New (to me) Turbocharger
    • New aftermarket exhaust
    • New gaskets
    Hopefully, I can get this running by the end of the year. After that, it probably wants new brakes, a check on the suspension and steering joints and a damn good clean - the thing stinks of diesel fumes

    After a lot of stalling with real life madness and a odd boosting issue (described here), the CDI is back on the road. I know, its been over two years since I last posted in this thread.


    The list of issues it has is... extensive.
    • One of the rear wheel bearings is shot with the classic droning noise the faster the road speed gets.
    • There are lot of weird rattles and such which I need to investigate.
    • It is rather a pig sty on the interior front.
    • The engine also really wants a service.
    • I suspect a lot of the suspension components want replacing.
    • The wheels need repainting or replacing.
    • The tracking and wheel balancing needs doing (some vibration in the steering wheel at 70mph).
    • The key needs a new button for the boot release.
    I could go on...

    However, the thing runs. It did a 200 mile round trip over the weekend to North Wales without missing so much as a beat though I need to get used to how a 450 brakes again. I put some diesel injector cleaner in there over the two fill ups since it has been running again and it seems to have helped with making it feel less arthritic.

    I'll see if I can get a video of it over the weekend.

    Sounds very typical of a 450 that's spent most of it's life in rather uncaring hands. Mine was in a very similar state when it was given to me, with the addition of an engine that barely ran on two cylinders and smoked like an old two stroke.



    Unfortunately I can't help myself when it comes to cars and bikes; if I like them I feel compelled to get them as close to perfect as possible which typically means spending a lot of time and considerably more money than the car is worth! Now it's a Brabus spec car with a fully rebuilt roadster engine, all new brakes, suspension, Roadster spinline wheels etc. and it's a hoot to drive.



    I agree with the brakes though, they work well enough but they feel vague with more pedal travel than I'd like despite fully bleeding using Star system and pre-adjusting the rear brakes. The brakes on my wife's Roadster feel perfect and AFAIK the only physical difference between them is the brake pedal and the way it pivots.

    Mine had quite an impressive improvement in braking performance by changing rear shoes. Resulted in normal pedal travel. Later fitting Euro pads and discs in the front made the brakes just perfect.

    Rear shoes were fitted to this before it came back on the road. Front pads that are on the car now had plenty of meat but a space box of Eischers are ready to go on when they expire.

    Finished the course of injector cleaner. The MPG seems to have improved a bit but all things are subjective. Next thing to do is service the engine and sort out the interior.
