Project Bluebird: The first 730 miles

I should probably do an update on Project Bluebird, seeing as I have actually been able to drive it. Hoorah!

As related last time, I was forced to park the Bluebird up after its first trip out, as the shock absorbers were dangerously shot. KYB kindly supplied a set of its excel-g gas shock absorbers, after I asked for advice about trying to improve things beyond standard. Gas shock absorbers, or dampers, use nitrogen gas to control the springing of the car – literally damping things down. Now, I’m quite used to the damping effects of nitrogen after many years of driving hydraulic Citroens. The main benefit is that the damping range does not change, whereas hydraulic dampers will suffer a loss of damping ability as the oil heats up, and the viscosity changes.

Bluebird gets some love, and DFTR Automotive, Dudley.

I visited DFTR Automotive in Dudley for the fitting, knowing that Dean has a good chunk of experience having worked on these cars when they were new, though Mazda rotaries are the main love of this family-owned firm. With a two-post lift and power tools, the front struts were removed, the springs compressed and the new dampers fitted in no time at all. The nearside front, as I suspected, was in terrible condition.

The rear was more involved, mostly because the rear seat needs removing to access the upper strut mounts – not an issue if the spec includes a folding rear seat, or if you have a hatchback. The seat clips really didn’t want to give up their hold on the seat, but we got there in the end. Removing the struts is also a bit more involved, with the multiple suspension links needing to be removed, and the brakes before you can pull the strut out. Still, a few hours work and the Bluebird was feeling a whole lot better.

Back seat needs removing on Bluebird saloon.

In fact, the difference could barely be more marked. I’ve just changed the dampers on the 2CV too, though that transformation was more marked. The 2CV is now limousine-smooth once more, while the Bluebird still rides like Bluebirds always did – a touch bouncy at times and you know about every bump you hit.

The transformation has come in terms of handling, though. I can now safely chuck the car into a bend and know it’ll track neatly around it, even if I hit a bump mid-bend. Even when you aren’t walloping into bumps, it still corners much more neatly. Body roll is better controlled, and its horrible habit of lurching mid-bend has utterly gone. Sure, it’s still no sports car, but I can once again corner with enthusiasm. I live in Wales. This is how I drive very often.

Today, there was further work to do, as I set about retorquing the cylinder head bolts. This should be done after 600 miles, but I thought 730 would do, as that’s what I’d covered. I imagine a lot of cars miss this essential step, which is perhaps why so many cars suffer head gasket failure after a repair. It isn’t particularly hard to do, though the fuel pump needs removing to provide adequate access to one of the bolts – just two nuts and it’s away.

With that done, I could check the valve clearances. Annoyingly, the head bolts should be tightened with the engine cold, but it’s best to check the valve clearances hot. That meant putting the rocker cover back on and running the engine up to temperature before taking it back off again. A couple of clearances were a bit slack, something given away by the slightly tappy nature of the engine. That’s perhaps because I’d set them cold initially, as I knew I’d have to reset them later anyway, after re-torquing the head. I’d set them a little on the generous side back then.

I also disconnected the manifold-to-downpipe joint, as the gasket on it is very poor. It didn’t have one at all when I got it, but the gasket I had in my gasket kit was a poor fit. I slapped a load of exhaust paste around and did it back up. The result is that it is now much quieter.

Looking good! A quick clean makes all the difference.

Having given the Bluebird a wash ahead of a local show, this really is starting to look and sound like a car that has been vastly improved since purchase back in May. There are still some issues – a leaky sunroof (the frame that holds the glass is rusty), a cracked dashboard and the heater matrix is still slightly clogged. Plenty to be cracking on with then, as the car settles in to shared daily driver duty. I think I might quite like it though…

  1. Hi Ian

    I recently came across your youtube stuff and i was quite impressed.
    I live in south africa and work in the film industry and we shoot a lot of car commercials for Europe so i am always in contact with all the up and coming models.

    Anywho i was intrigued by your citroen xm.
    We have one in our workshop but with a very interesting modification, we converted it to a pickup as we needed a tracking vehicle.

    I just thought you might be curious to see what i believe is the worlds only Citroen XM pickup.

    • Sounds intriguing, though I know Tissier in France converted several XMs for filming – proper extended-wheelbase monsters! Still, I’d be interested to see yours.

      • Ok cool.
        I was not aware that they had actually made others.
        I am not sure if the one we have is a long wheelbase but i do know that we have a 3.0 V6 version.
        I would gladly take so pics for you to see the work we did to the vehicle.

      • Hi Ian

        Here are the pics of the XM pick up in Cape Town South Africa. My Boss informed me that the vehicle is currently for sale. Let me know what you think
