I had a small setback this week.........
I opened the garage door to find a small puddle of power steering fluid on the concrete. My recon steering rack is leaking fluid.
I assume the seals have dried out and shrunk or possibly the seals have been damaged by turning the steering without any fluid. With hindsight (that wonderful thing!) I think I should have found a way of keeping the rack full of fluid.

The leak seems to be coming from this 'dust' cap.

I have another used rack that I may try or get recon'd.

But I have decided to leave it for now and worry about it nearer to the IVA test.
So moving on with some more progress....
My plan was to mount the cooling system header tank something like this.....

But that was two years ago and before I had fully worked out the heater hoses and the outlet clashed directly with the heater control valve.
But I found that rotating the tank through 180 degrees meant the outlet cleared the heater hoses but made making the mounting brackets a bit more challenging. Here I am checking the tank clears the bonnet represented by the piece of wood.

Here is the top bracket finished and bolted to the scuttle cover. I put a strengthening plate on the inside of the cover.

The lower bracket was made from 4mm thick steel strip to support the weight of the tank and coolant. Again, a support plate was mounted on the inside of the cover to strengthen it.

And here it is finished.

Next it was on to the Idle Control Valve (ICV) hose....
Because the inlet bellows to the throttle body is upside down (compared to the way BMW designed it) I needed to find a way of feeding the idle air from the inlet bellows to the ICV that is mounted under the inlet manifold. I used silicone hose and Mikalor wire hose clamps. These are much cheaper than Jubilee clips, neater and so much faster to install.

The hose drops down the gap between the throttle body bellows and the inlet manifold and then through a 180 degree elbow up into the ICV.

It was then on to the brake servo vacuum hose with a new length of pucker BMW hose.

So that's the progress this week and I'll leave you with this photo.....

To check the clearance of the header tank I temporarily installed the radiator cover.
I couldn't resist taking this shot and doesn't that BMW straight 6 engine suit the Sabre!
Next week I shall be working on mounting the radiator......
