IVA Fail...
Dave Bailey - 29/7/13 at 01:52 PM

Well arrived at 08.00 this morning at Southampton for the test and finished at about 12.30...

Tested the Vehicle with the screen and got I hope would be considered as a 'good Fail' Some frustration not with the tester who was very fair but on myself because the fails probably should have been avoided...

1. Number Plate light Showing slight white to the rear.
2. Interior Mirror not permanent... Suction type not acceptable
3. Used PTFE tape on Brake fittings... (Not allowed)
4. Front / Rear bias (rears locked first)
5. Radius on the bottom of the dash. 15mm approx. measured needs to be 19mm. Annoying should have checked this.. Was told that the Carbon Mods Dash was ok...
6. Exhaust Mount Bracket incorrect radius
7. Low handbrake effort 16% should be 18% min
8. Vin plate plug welded.. needs to be seem welded.


Might have a beer tonight to celebrate the 'fail' then start planning the retest....

Thanks to everyone on the site who helped me get this far...

Sounds like a good fail and should be mostly easy fixes. I'm sure there is something in the IVA manual about dash radius being different between hard and padded surfaces


adithorp - 29/7/13 at 02:14 PM

Hard Luck. Not a bad fail.

1. Being picky but if it shows, it shows.
2. Not the first to fail for that.
3. Thats def' a no no.
4. Whats your set-up? Are the masters different diameters and the right way around?
5. Odd one. My CarbonMods dash is 40mm diameter on the bottom edge so easily 18mm dia'.
6. Get filling.
7. Might be right with some bedding in.
8. They've just changed this so easy to get wrong.


theprisioner - 29/7/13 at 02:36 PM

Good fail

1. Unlucky
3. I did so too but managed to conceal it from the IVA man, the Willwood callipers would not seal without it, tried everything
4.The first important thing they found!
5. I used Plaskool dash, different radii??, sounds like the rubber is coming out.
6. Trivial to fix
7. Almost got caught by that one, had to do extensive bedding in trials on the way to the IVA station
8. Welder out!

If the brake pipe won't seal without PTFE tape I'd suspect the end of the pipe has been made to the wrong shape. I'd shine a light down the calliper hole and see if it is a conical pit or a cone, each need a different pipe shape to seal


Irony - 29/7/13 at 03:13 PM

Not a bad fail.

If you can't use PTFE tape then what is the best solution? I haven't filled my braking system yet and I have used PTFE tape. Guess I shall be removing all the fittings then!

The VIN plate has to be seam welded? I thought you could get away with riveting it? I don't have access to a welder so this poses a problem for me.


theprisioner - 29/7/13 at 03:22 PM

Would somebody tell me what is wrong with PTFE tape, I have no evidence of it being dissolved by the brake fluid?

If it's a brake union it should not need anything it should seal on the flare. If it's a banjo fitting annealed copper washers should be used either side of it.

copper pipe and the right fittings and a decent flairing tool

copper pipe seals better as its softer and re-shapes itself to fit as you tighen (well all of them do a bit, but copper is the softest/easiest type) so even if the shape of the union/calier/flare isn't perfect it compensates



I've never done any more than this on any car I've ever had - and no leaks yet

Mr Whippy - 29/7/13 at 03:46 PM

PTFE tape often tears when fittings are tightened up can get into valves causing them to not seal. Using it on brake fittings is just ignoring the real problem that the copper pipe is not seated correctly, mind too that the PTFI does nothing to seal up the pipe going through the union.


MsD - 29/7/13 at 04:14 PM

All relatively easy fixes then- the good work!

Can you explain what number 1 means?
Mark.


chrism - 29/7/13 at 05:20 PM

The VIN plate one doesnt sound correct, I thought it was only the chassis number plate (If not stamped directly into the chassis) that needed seem welding, and that the VIN plate was OK just being riveted.

Possibly just a slight misquote by the OP?

Numberplate light should be shrouded so the bulb cant be seen from behind.

Could possibly be a bad design exagerated by the angled back panel if its a seven.


MsD - 29/7/13 at 05:38 PM

Thanks for the above reply's regarding number plate light..

Re. PTFE on brake fitting...

It shouldn't be used (or needed) on brake unions as they should seal on the flare and banjo fittings on the washers as others have stated. If it doesn't something is wrong with the flare (or machining of the hole).

If the offending item is the tapper fitting adapters on Wilwood calipers (as with The Prisoners car), then I'd understand it's use and I had to resort to it on mine. Despite my best efforts and years of experience, it was the only way I could prevent them weeping. I left a section in brake fluid to test it's reaction and it had no effect on the tape. I was careful not to overlap the end of the fitting to avoid any getting inside the system. I also trimmed back the excess so it wasn't obvious.

THIS from Frosts is the only other alternative I know of. In the picture it's being used on a union and shouldn't be need.


...now I'm going to run for cover.

If a brake fitting will not seal without resorting to bodging with PTFE then the flare is not up to standard or the wrong fitting has been used.


theprisioner - 29/7/13 at 08:00 PM

In principle I totally agree, as I said a total last resort. As you say the two devices should have been compatible, were the correct thread, were tapered, one was plated steel the other was Wildwood alloy. One day I may take it off and change the RD (Euroquip) hose of another make. I don't have a lot of faith in RD stuff for other reasons. This is the second product


Dave Bailey - 29/7/13 at 08:04 PM

Number 1 was as result of the slope of the rear panel....

Ref the PTFE tape I used this on the front calipers to seal the braided hoses to the wildwood caliber... I need to take it apart and see if either the hose or the calipers has a taper....

The plate that needs to be seam welded is the chassis identification number.....

Thanks for the feedback... and support....

The Wilwood Powerlite caliper has a taper hole. Not sure of the thread (prob' NPT) but the Powerlites are usually supplied with an adapter that fits and converts to standard M10 (male) brake fitting. Your flexi shouldn't be fitted direct, although the tread is close to a match and could be screwed in.


Dave Bailey - 29/7/13 at 09:05 PM

Thanks everyone....

Andybarbet - 29/7/13 at 09:53 PM

You should be well pleased, although it was a 'fail', not a bad list of fixes.

Bet your glad you stuck with IVA'ing it with the screen on too

Nice one.


Dave Bailey - 2/9/13 at 04:43 PM

It Passed


Dave Bailey - 2/9/13 at 04:44 PM

Bring on the DVLA!

So good he said it twice

But well done!


adithorp - 2/9/13 at 06:20 PM

Nice one!


Dave Bailey - 2/9/13 at 07:05 PM

I couldn't have done it without you guys..... So a huge thank you to all on the Forum....

Dave B


Dave Bailey - 2/9/13 at 08:12 PM

Just had time to look at my approval cert... One thing that seems odd is that they have put 127kw / 6500. And yet I have a 2.0 ST170 motor in the car...

Any thoughts?

Dave B


Dave Bailey - 2/9/13 at 08:15 PM

Forget that... 127kw is 170 hp I have just realised....

serieslandy - 2/9/13 at 09:38 PM

Well done for the pass, have fun with the dvla. It seems to take a long time now you can't just go the the Pompey office.


Dave Bailey - 2/9/13 at 10:00 PM

Already started the fun with the DVLA.. They say it will take 4 weeks plus although I achieved the latest emissions they don't care ... The tax goes on Engine size so is 225 per year. Is this right? Just hope I can get an age related plate....

David B

mcerd1 - 3/9/13 at 10:36 AM

^^ yeah thats the right tax for any kitcar with an engine over 1549 cc
(they are treated the same as cars registered before march 2001)


your emissions test has nothing to do with the tax band - that is set by getting you car model and engine combination 'type approved' (i.e. what production cars do instead of IVA tests)


and well done on the pass

Nice work mate, congratulations.
