    Hello All...

    This is kind of funny, but certainly not fun! The other day I was installing the rear PS exterior door handle on my 82 QPIII.
    I thought this was going too easy given the tight quarters to install the mounting nuts, while holding the handle such that
    the exterior door handle gasket stays in place as well. I got all done, made sure the door knob was not in the lock position
    and shut the door! When I attempted to open the door by pushing the square push button on the exterior handle, the whole
    thing basically blew apart inside the door... Upon inspecting the remains, these things are/were made of plastic and pot metal.
    I guess 37 years has taken its toll! Fortunately, MIE does have replacements... As I said, funny, but not fun!

    Jarle: Have not heard from you in a while - how is your car coming along?

    I would start by removing the spark plugs and putting in a generous amount of Mystery Oil into each cylinder. Let the oil soak in for a few days and the hand turn the engine about 90 degrees. Put more Mystery Oil and let it soak again for a few days. Now you are ready to hand rotate the engine (in the normal direction of rotation!) several times to make sure the engine "feels" right. If everything seems ok then it is time to change the engine oil and filter.

    Still with the spark plugs removed; disconnect the fuel pump (either the fuse or relay) and use the starter to rotate the engine. I like to install a mechanical oil pressure gauge at this point and rotate the engine with the starter several times until oil pressure is indicated. You have now primed the engine with fresh oil with minimal engine stress as the spark plugs are removed. You should check that the ignition is operational at this point. Your car should have electronic ignition therefore timing should still be ok.

    The next step is the fuel system. This will required the most work as the old fuel will have degraded and you want to make sure none of the old stuff gets sucked into the engine. At a minimum remove and clean the gas tank, and replace any fuel filter, including the one inside the tank (if there is one on the QP3). The four carbs will need to be taken apart and cleaned and the accelerator pumps replaced as they are most likely hard and brittle. The fuel lines between the carbs are likely hard as plastic ... replace them. Put fresh fuel in the tank but before connecting the line to the carbs run the fuel pump with the line going into a canister. This should clean anything that was left in the fuel lines. Make sure the fuel looks nice and clean. Put a fuel gauge and test for fuel pressure of around 3 psi. Connect the fuel line to the carbs, start the car ... and pray.

    You will get a lot of smoke, do not be alarmed. Some of that Mystery Oil ended up in the exhaust and will need to burn.

    Struggling a bit with detaching the oil pump from the crank. Anyone done this? Have proper puller, tried heat and all the tricks in the book. No can do.

    All tips received with thanks

    After several heat cycles we got it off.
    That gear is a tough sucker that is for sure.
    Tackling the liners is the next job in line.
    As well as bebuilding the calipers in front.
