Does it push into the body of the servo with a grommet  Terry ?

I think so Kev. here is the fitting instructions for the servo

That's going to be a bugger to get to -the vacuum hose pushes onto a swivelling plastic union on the back of the servo & I've built a gearbox tunnel around it.

Had a panicky hour or so this morning hunting for the folder with all the test info in. Finally found it so I can phone the test centre tomorrow & try & book the re-test.
On my way to the workshop I called at Dslam's place & picked up his vacuum & pressure brake bleeding gear. Thanks Andy.  He'd also nickel plated the MonkeyHead bonnet badge for me. Looks super shiney now. I thought I'd put it on as a good luck charm for the re-test.

The speedo's out of the dashboard at the moment, which reminded me there were a couple of jobs to do behind it -a servo mounting bolt missing it's nut, a securing clip on the demister vent linkage forgotten, the windscren washer jet mount being loose -that kinda thing. So I spent an hour or so fixing them. Then I drilled the bulkhead & added the brake pipe retaining clips I made the other day, using self tapping screws. Not keen on self tappers, but that part of the bulkhead was put in by a previous owner & is nearly 4mm thick, so the screws hardly penetrated. A bugger to get to, behind the exhaust headers, but worth doing. The brake pipes are wrapped in heat proof sleeving for the test.

Kev mentioned the other day that the wheel hub nuts ought to be covered by grease caps. They didn't mention them on the test, but I found a couple on Ebay. A little loose though, so would need retaining, maybe with a spot of weld on the back, just for the test. If they stay they'll be painted black.

i may have miss read  but what problem are you having with a valve on the servo ? ?  is it the vacum none return valve ?

[Manky Monkey]

Not sure if there's actually a problem Mike.
I've just ordered some proper rubber servo hose, to connect it to the carb take-off, because the stuff we used was too thin walled & sucked itself almost flat, restricting the air flow. The first time you press the brake pedal after the engine's been switched off, there's a rush of air, either into or out of the servo. Sounds like an air brake. Maybe they always do that & you don't hear it, but ours is under the dash in the cab & not panelled in yet.

alot of rover v8,s had a ,check, /non return valve screwed into the inlet manifold where the vaccy hose connected.

but with you fitting the ,holley, i,m unshure where youre ,vaccy, connection is  but you can get an inline valve ..

Thats a good sign Andy, its normal for a servo to vent when you apply the brake with the engine off, if it did'nt you would have a problem. Also if it only happens when you brake, the servo must be a none return valve already fitted or else it would'nt happen. (Next time you get into you road car, after you switch the engine off pump the pedal and listen under the dash.)
As to your grease caps, mine were loose, but I just nipped the around the edge with mole grips and its now hard to get the back off.
(Still looking forward to the video  )

I thought about it during the day as well Tony and remembered it was still holding vacuum after the  engine was switched off ( and also depressing brakes while running makes NO difference to engine ).

The only issue with the brakes ,apart from air still being trapped, is that the vacuum hose isn't correct material and collapses as engine is running so servo isn't getting emptied as much as it should.

As you say the method of operation on ANY servo is that movement allows atmospheric pressure IN to assist with braking. Venting /hissing is perfectly normal.

Yup, kinda thought that myself, but I'm happy to learn & not afraid to admit I know nuffink. 
Another visit from Uncle K this afternoon -I'm gonna owe him so many favours. We pressure bled the brakes several times using Mr Dslam's gear, allowing time between each go for any remaining air to settle. They appear to be doing just what they should now -the fronts lock well before the backs & with the aid of the servo, there's very little effort required to apply them. Hopefully they're good to go now. Kev also tweaked the carb a little -2 pumps of the throttle pedal, turn the key & it bursts into life straight away.
I rang the test station in Southampton this afternoon & booked the test. 8.o.clock in the morning on Tuesday the 20th. Even though they're only checking the failure points from last time, the test could still theoretically take 3 hours, hence the early start. It also has to be done by the same guy who did the first test. Scottie's confirmed he's O.K to take it there again for us, so will be collecting it on Monday afternoon, so he can drive straight down in the morning. We'll meet him there at 7 to unload & warm it up.
So I'd better get cracking with the interior panels.

[merv]

All the best with it.
I'm sure with all the work you done on it you got nothing to worry about

[Manky Monkey]

Uh huh.
