    My 744 Resto / Saviour Project

    Been a while since I done any wheeling and dealing, so when I was offered the 744 it was hard to refuse. I knew it potentially needed an engine due to blowing a rad hose and overheating with the previous owner.



    The car arrived, engine turned over as if the timing belt was broken, it had no compression. I put some oil in the cylinders and got the compression up, my thinking being the heat had left the cylinders dry. Next was to get a spark, the heat must have fried the dizzy sensor, so whipped the dizzy out of my 740 and fitted it to this one. We now had spark, some compression and fuel. We also had a new exhaust port on the top of the cylinder head which used to be the water inlet. Conclusion was, engine is scrap.

    Head gasket from the old engine


    So, next was to pull the engine.




    I had a good bottom end which was rebuilt with new shell bearings, a good head and the "bolt on" stuff from the 744 was good, out of 3 engines I built a good one.



    Now ready to go back in, new head gasket, new rear crank seal, new sump gasket, new timing belt, new injector seals etc etc



    Engine in place and gearbox bolted up.


    When I tried to start it, it turned over well, had spark but wasn't getting fuel. I discovered 2 fuel pipes fitted the wrong way round, swapped this round the it fired up and ran well.

    Only filled with water until I see what water leaks develop and some cheap oil as I intend to change it again after a few miles. Got it out for a drive, engine running well, shame about the rest of it. Brakes juddered, steering was vague at best and half the dash lights don't work.

    Got the car up in the air again, the dog helped!! Brake disc on D/S/F was cracked in 2 placed,. caliper was seized, track rod end was knackered, passenger side ball joint was also shot.


    New parts fitted last night, along with some new alloys.




    Next is to address the lack of dash illumination, the faded rear lights and a good clean and polish.

    What's the matter with the car I'm driving?
    Can't you tell that it's out of style?
    Should I get a set of white wall tires?
    Are you gonna cruise the miracle mile?

    Good stuff.

    Any flickering on the dash lights when you play about with the rheostat?

    Did you happen to get anywhere with the funny idle on your other one? I think mine is a tiny bit better after winding the adjuster all the way in to close it off, and just adjusting the throttle plate instead. But it still idles around 1100 when warm (currently doesn't idle at all for that matter - broken hall sensor I think)

      The dash lights are just down to bulbs, like any old Volvo, nobody wants to replace them lol

      Yes, I did manage to get it idling better, I screwed the idle control valve will out and adjusted the throttle stop to suit, found a happy medium that it seemed to idle well at. It now seems to even drive better, not sure about fuel consumption yet as I've not really been driving it. Now I've played with this GL I understand the injection a bit better so I'm going to have a play with mine and get the cold start working too.

          Andy

          The 740 resto project is really happening, engine rebuild etc. I am impressed.
          Looking forward to viewing and driving the 740 next Friday
          A quiet day at the garage, I don't think so!!

            Garage hasn't been quiet in a few weeks John haha

            Just doing what I would do with any car I intend to sell, leaving it right!

            I think it is going to turn into a diamond from the rough!

              Great job, and nice flooring in the garage too. It's great to read about another one making it back on the road again.

                Its actually my living room, I like working in front of an open fire :kilt:

                Its actually the way the garage was when I moved in, think it was built as a games room, the walls are dry lined and painted, ceiling done in plaster board and carpeted and heated, makes a nice area for working in :)

                    Good work! unexpected exhaust pots are not usually beneficial.

                      It was indeed, lad from Lisburn bought it. By all accounts the "mechanic" working at it was a bit of a butcher, so I'm slowly sorting out his balls ups.

                      Been out driving over the weekend, still an issue with the brakes, judder in the pedal and all discs are new, should be interesting to fix...




                      Has a misfire on idle too but as soon as there is a load on the engine its perfect, should be another interesting fix.




                      Got washed yesterday and back in the garage to keep dry for cleaning this week.

                        Looks nice!

                        The brake judder may well be due to the butcher not cleaning the hub surfaces adequately before fitting the new discs - I put a small wire brush cup in my drill and clean up the surfaces with that, then give it (the hub lol) a quick wipe over with some copper grease and job's a good un.

                        The poor idle is possibly due to the throttle body being claggy. Give it a good clean and make sure the small (tiny actually) bypass hole/channel is clear. Clean the idle air controller too if you have one, and that should help no end. Might be worth your while checking all the vacuum lines for perishing too - the rubber elbow joints don't age too well and frequently split causing poor running.

                          Yeah, going to pull the rear brakes apart and have a look as there is a drive line vibration too and I think the P/S front is sticking a bit too, so need to look at that again as well. The idle seems to be related to idle control, my theory coming from the fact once driving its running perfectly. So the throttle body could be a good place to start.
                          She needs TLC, I notice more and more little things which need attention cosmetically but mechanically she seems to be a good motor and with a few weekends tinkering and some replacement bits it will become a tidy useable classic.

                          Then again, I'm very fussy and the next person to look at it may not see the issues I see and think its wonderful as it is lol

                            Judder

                            If you find out how to stop brake drone judder and weave I want to know! I think every single one of my 5 has a larger or smaller issue with these things, they get improved by stripping and freeing the brake calipers and seating the discs and adding new pads - and soon it's back again. It's getting very frustrating. Maybe I need to institute a more strict rotation of which one I drive on which day...

                              My own 740 does it too, but not as extreme as this one
