Take the servo out of the engine problem equation by disconnecting and blanking the vacuum line from the back of the inlet manifold.

Remove the servo from the brake problem equation by making up some new short pipes and re-routing the fluid path from the master cylinder straight into the junction block (missing out the servo)

You can also check to see if the vacuum pipe is wet inside from brake fluid. Does sound like servo

I understand the second point Jim but could you explain what this is doing and how it proves things? Is it proving a leak in the servo or lack of vacuum or something?

Oakesy, would this imply brake fluid being drawn up the vacuum pipe and being burnt in the engine?

Sorry if these are daft questions....

I think its just proving (or not) the servo caused the braking problems. By simply removing it from the braking circuit, you can see if there's any differance in feel or braking power

Yep - the white smoke is highly likely to be brake fluid (but doesn't explain the lack of power unless there was enough to really weaken the mixture) - the only place they're connected is the vacuum pipe. You also said the brakes were sticking - taking the servo out of the equation proves or disproves it's at fault.

How do. Halfords classic 20/50 is OK, rev the nuts off my GTE553N with it in and it don't mind! Change it every 3k miles. By 'eck, yours is a nice one too, good year as well!

Thanks Jim, will look at this once the snow has gone.

Thanks, will get this oil then. She does look pretty good up close and makes me smile, would have like a '73 as that was the year I stopped just being twinkle :D

Hi Gerry, Ian here (the one with the 5a project that you saw the pics of).
Although I have virtually no mechanical knowledge at all, when I initially got my 5a it had/has brake issues... One of the first things that a couple of friends asked me was if it was throwing out white smoke? Sure they mentioned boiling fluid and it being sent into engine and burnt off creating the white smoke. As far as I'm aware (correct me if I'm wrong folks!!) the older scimitars tend to be a little temperamental with the braking systems...
On the plus side - she looks a beauty! Sure you can sort out some new door seals if they're required and who needs a stereo when that engines running sweet...
Good luck with it!

Hi Ian, good morning, nice to hear from you, thanks for the photo's.

The more I think about it the more the brake issue is playing on my mind. I have a receipt from the previous owner which includes freeing off the rear brakes?? and the morning I picked her up he said the brakes released with a bit of a bang but put it down to not being used much lately. :roll:

I will do the compression test with my fingers firmly crossed and go from there I reckon.

Thanks Dave, like I said, fingers firmly crossed.....

Sometimes there isn't much life left in the components even if they appear ok. So you get her going and those bit die after a while (1 month, 6 months etc). Have heart. You will get some much back out of her. They get under your skin.

have a look at this,its sums it up perfectly

Thanks for that, She looks best in photo's :wink:

Well, compression tester didn't arrive so nothing on that front. I managed to get her running but it was painful, she took forever and then when she did fire up it was as if she was only firing on 2 or 3 cylinders and really lumpy and any throttle killed her immediately.

Will it be ok if I have to do the compression test on a cold engine? I guess I am ultimately just looking for a big difference between cylinders?

I know this is bad but I felt the leads going into all cylinders and the only ones that I got a buzz off were the back left pair as you look from the front, 3 and 5 if i'm not mistaken? I felt absolutely nothing from the others? It was bl**dy chilly though so wasn't out there long. I don't know if this proves anything?

I have got new plugs, just waiting on leads and the previous owner said the coil is (and looks) new so will change them all when they arrive. I was thinking of doing the dizzy cap and rotor as well? I am assuming she isn't electronic ignition yet but can I use the same rotor and cap if she is? It just makes buying a bit simpler.

Oh and I'm fairly sure she already has a lockheed servo, it has a metal tag that I believe says lockheed and also the big white plastic disc that I have seen in photos, are these units pretty reliable or could it still be a part of the problem?

Typical, been off work since the 9th December and now I have stuff to do I have no time. Back to work Monday and everything is covered in snow :evil:

The Girling and Lockheed servos are very different in appearance but that doesn't mean it hasn't failed if its a Lockheed replacement.

Next chance you get, disconnect the servo hose (runs from the servo to the back of the inlet manifold) and assuming there's not a split in it, plug it with a bolt, then try again to run the engine (as per scimjim's note earlier). That will eliminate (or not) an air leak from the servo or pipe itself.

Ok Phil, thanks. I should have done that today but I didn't, I was a big jessie and scurried off indoors instead :oops:
