    There are some myths around working on these cars, so just wanted to write a short post about it.

    1. You can get the headers out with the engine in the car. On the right side you need to remove the starter to free up enough space. From what I can see left side should be possible as well, though you might have to remove the steering rack.

    2. It's probably the easiest to remove the engine without the gearbox. If you take off the starter bracket, you have good access to the bolts on the flex plate. You need a lift for this though, it's a hassle doing this lying under the car. You don't need to move the gearbox a lot to get it off, maybe 2 inches. The engine and gearbox is a long unit, so is a hassle. We removed both though, since we are changing some seals on the gearbox as well.

    From what I can see I have to change two liners, heard a lot on how involving this is, will have to see if this is something we can do ourselves or not.
    Engine is currently on an engine lift, where we can turn it all directions to asses the situation properly.

    Good idea! Here are some!

    Everything is beeing stripped, blasted, painted or zinc treated.
    We try to get the right treatment on the right places.
    If it's originally painted, we paint it.
    If it's zinc gold, we zinc treat it.
    Changing bearings, gaskets and so forth.
    Distributor, carbs, starter, gearbox is checked and refurbished.

    Hello Jarle…

    Welcome to this thread !!! Please keep the photos coming, and I promise I will try and do the same!
    Mine is 1982 model, what year is yours? I believe you are also active on the Biturbo Zentrum, correct?
    I have read many, if not all, of your posts on that forum!

    Here are some photos of my QPIII's brake master and Engine Compartment Fuse Box showing the wiring!
    The brake master looks very very similar to that of my 1972 Ghibli SS - may actually be identical! The wiring
    for the engine compartment fuse box looks pretty good - may just need to clean the box up good and check
    any and all grounds involved! o_O

    Hello again Jarle…

    Since yours is a 1982 like mine, I would recommend you get the 1982 Parts Supplement, if you don't already
    have a copy... Ivan should have it on his site, as I loaned a copy of it to him to put on his site (carnut.com)…

    Project continues. Gotten a lot of parts back from Chrome treatment, but need at least one more visit to that shop.
    Started to putting some of the refurbished parts back together. Changing bearings, painting, cleaning up everything.
    Heatshield refurbished with new asbestos on it. My mechanic friend has everything in his storage :)

    Here are some photos.

    Hello Jarle…

    I just got back from a cruise and am looking at your pictures!! Everything is looking great !!! I especially liked the Carlsberg glass by the alternator...
    (you want to make sure you don't get dehydrated while working on these items ! :) )… Keep up the good work, and I will try and begin posting pictures
    and progress (although slow) soon!

    Also, where was the heatshield located? I don't think this was on my car, but my memory may be faulty!

    Heatshield is around the starter, to protect it from the headers.
    I think the wiring might melt unless it's there. In the long run though.

    Beers & mechanic work belong together :) Hydration is the secret, agree!!

    Currently putting the carbs together, they look smashing. Will post pictures closer to the weekend!
    Looking forward to seeing more pictures of your work!

    I am also working on my carbs.. Attached are some pictures (before and in-progress)…

    I cleaned my carbs in an ultra-sonic cleaner. The results can be seen in the second picture
    where one carb went through the process, while the other 3 did not (at least when the picture
    was taken)… The cleaner did a good job, except for one thing. I did not disassemble the
    butterfly mechanisms, as I was afraid after so many years the shafts would be slightly
    warped. The butterflies did rotate easily before processing in the cleaner. Afterwards
    they were very difficult. I greased the shaft bearings located on the outside of the carb
    body, but this did not help a lot. I did note a lot of carbon buildup on the shafts where
    they pass through the carb body. I began cleaning this up, and the butterflies are rotating
    a bit more freely. Much work still required!

    I thought I would also send a couple of pictures of other fuel system parts..
    Attached are two photos of the fuel pump setup on my car. The first is of the
    main and emergency pump (both are the same make/model pump) attached
    to their bracket as removed from the car. The second shows the main fuel
    pump(s) and related components after some cleanup!

    And finally, a couple of pictures of the intake manifold and fuel tank! The fuel tank has been
    boiled out and is now ready to go back into the car! I will send more pictures of the intake and
    the surrounding carb box in a day or two, as these have been cleaned up as well!

    Liners might fall out if you leave in a heated spray shop booth to let the block get hot. I have a complete engine internals but only 4 liners 8 pistons & everything else. 4.9 qp3. John.
