Ford Ka MK1 Coolent flush - query and questions

Started to look over the valve cover removal procedure using the service guide:

It looks pretty straight forward, however, this is one hose that is not referenced on the guide, and it's a bit more obscure how to move or remove it to access the valve cover. On their guide it seems to be routed around the side, and just needs to be unclipped. On this it is routed over the engine cover.

It comes from the brake master cylinder vacuum component.



The connection to the brake component does not look removable:


Then it has this connection about half way:


And terminates in the engine block as part of the air in-let


I assume it's the vacuum line. But I'm not sure the best way to remove or dismantle it.
The connections are not similar to the other more simple hoses. It's very rigid and cannot me easily moved aside.

It’s just a push fit into the brake servo....dont try to separate this pipe anywhere else.
Just ease it out with gentle twisting, add some silicone spray if you like and move it aside.

Just to clarify, that is this connection, correct?



Just want to be 100% sure.

Also, should expect air to escape etc. Just want to be prepared for any noises that may make me think I've broken something

 

[Burnerman]

Yep, that’s the one......there may be some vacuum in there but I doubt it!
Gently ease it out, the end is serrated for a good seal. Apply some silicone spray as you replace the pipe.

Thanks, I only mention that as I'm sure I knocked that connection while wrestling with the heater control valve and I heard a pssst of air escape for a moment and I thought I had damaged something.

 

[Burnerman]

Yes, with the engine running there will be a vacuum in the servo.
The other end of the pipe goes to the inlet manifold ( or vacuum pump if a diesel).

Just reviving this thread a bit, as I was planning to replace the rocker cover gasket as mentioned on page 2, but...I never got round to it.

Now the weather is improving, I may give it a go. In the mean time, I found this rather nice video.

My only questions are actually related to what I asked on page 2.

1) In this video he runs a bead of sealant around the surface the rocker cover mates to. But according to you guys on page two, the gasket sealent should only be used to keep the gasket from falling out of the rocker cover when installing.

So I assume he is wrong to do what he is doing.

2) In this video he removes the rocker cover without moving that brake servo line, which makes it a bit more awkward. On page two you guys said it was just a push-fit into the brake servo and removing it was not an issue.

Just thought I'd check those two points.

If there is anything else I should check or that the video is incorrect about, I would be most appreciative.

If you do remove the servo pipe, just be a bit careful when pushing the pipe back into the servo that you don’t push the rubber seal into the servo. Lube the pipe first with a drop of brake fluid. If you don’t have any spare, just dip a clean finger into the brake fluid reservoir and wipe it onto the pipe.
