As I had matched the new Mintex linings to the re skimmed wheel drums by hand (60 grit floor sanding paper and a block of wood) I was curious to see how well they were bedding in now?

I was well pleased to see that while they still have some ways to go, they are showing an even match across the linings.

Yesterday and when I put the car away for the evening, the engine started right away and with no use of choke, the only change to the fuel system has been to tighten a leak to the petrol pump feed pipe, so why has it made any difference?

Petrol has still to be in the feed line and down to the Stromberg float bowls, there is one thing only that I can think of?

The Nun checked my Zenith Carburetor page on the 125 CDs, the float is supposed to set to 17.5mm and not the Rootes factory setting of 16mm, does that have anything to do with the settings?

A petrol link leak will brake a gravity feed supply, the fuel tank is 3/4 full so enough to ensure a positive pressure to the float bowls?

Monday morning and the car required some choke to start it!

How it fires up during the course of the day will be checked.

The answer is a firm yes, as the car starts and runs cleanly once the initial cold start with the use of the choke lever.

To be honest i think the engine runs better and better with the regular use I am giving it now?

I once sold my 1975 Reliant Scimitar to a chap from Port Elizabeth, while he was down here and for three days I loaned him the 1967 Hillman Imp Californian so that he could move around during the period he was having a new exhaust system fitted to the Scimitar.

When he handed the car back to me three days later he commented that the car went very well for a 1300cc engine sized car, are all 875 cc Imp Sports this good I wonder?

My car has no hub caps, so to protect the threads of the wheel nut studs I have a set of plastic hex shaped wheel nut caps on the nuts.

The condition of the bare studs shows that they stay clean and lubricated.

Thanks,

Looks like what I need is an off the shelf fitting?

Locally I tried our local motor factors and a tyre fitment shop, no luck but a wheel specialist will have what I need I was told. Imp027

Checking the hard copy folder to the 1967 Imp Californian I note that in 1995 I asked for the following?

Imp Club spares I guess? 26/07/1995

This was to convert the cars original engine block to a close sport specification.

I had a spare series 180 cylinder head in stock, complete with sport inlet and exhaust manifolds and twin CD125 Stromberg carburetors.

Sport oil pump and bronze gear
2 Reintz head gaskets
Sump & timing cover gasket
Big end bolts
Set of standard piston rings
Spigot bush
Two Stromberg overhaul kits.

Also that the sport head was serviced by the Viglietti Ferrari service shop, new valves and guides plus BMW valve seals were fitted.

Which will be good reason to have an engine that runs so well, sorry about that oil leak of course :D

The picture shows new Imp Sport sized valves with bronze guides, I am not sure if the oil seals are BMW?

For sure the oil use in my engine and a lack of smoke says they work well.

Today I was off on a one hour drive to Tokai which is an area with motor trade shops, wheels and tyres included.
A phone call to TSW told me they have no suitable wheel center caps, the same at Good Hope Tyres, they know what I want but they also do not stock them :(


So this mornings task is to see if I can press a set of caps out myself? Imp027

Good and not so good?

I was thinking that the thin alloy jam jar top would deform easily, it was a little too easy and I think some thicker alloy would work better?

The wheel nuts became the pressure required to re shape the alloy disc, there are some sections that are not smooth but the cap
will in fact work, I may just use them on the rear hubs for now?

The front hubs have the domed covers on anyway.

I am now off on a new tack, what about a plastic end cap, they are used for tube enclosures, I have a 50mm one here, they are made in a 38mm size as well which will fit.

The black cap with the dome on it would look best but no local shops have those so I used what I had!

Plastic is probably best, they wont rust or even less liable to rattle, the Rostyle wheels originally had a cap that clipped in from the front though, but if they can be done from the rear then at least they become thief proof?
You could even machine some from hardwood and paint them matt black?

I used the clear lenses off some VDO marine gauges I have here, they are a bit too small so I have bonded them in with epoxy paste.

Yes but now its done I suspect that I need that center hole open to fit on a modern wheel balancer?

The front hubs do not have the same issue as the wheel nuts have covers.

Yes you will need the hole for a normal wheel balancer, though they do them them that can do it without, the early Innocenti Minis with the rostyle type wheel had a D shaped hole in the centre and they would not fit onto the conventional mandrel for balancing, a special machine adapter was used to take those wheels.

Yes, the local shop that balanced the wheels on Boris a few weeks back just threw the wheel on the balancer without looking and knocked/killed a centre cap as he did not check first.

I just removed the other one at the front and left two on back.

The young fella just did not know better but the machines need it, I think they always did ? not sure I ever seena balancer without the centre spindle

John
So I had a good idea that was not a good idea?

Not to worry, the correct style inserts will come to light one of these days, plus if the wheels need a re balance it will most probably be the front ones?

For sure the thin plastic caps I bonded in yesterday will be destroyed when they are removed.

Rostyle type wheels were fitted to most commonly, gt the 1275 gt mini, Cortina mk2 Viva gt, Hunter gt, Midget, MGB, maybe one the centres off those would fit? Or of course whatever your wheels were used on to start with?

My rostyle rims came of an RSA made Opel ( GM )of some sort? the nearside rim required a better masking off than I did on the drivers side yesterday, those silver plugs you located or the black plastic end caps I found would be a lot faster and I can reuse them as well?

I have never ever checked to see which Opel my rostyle rims came off?

All I remember is that Chris Walters who did the supply and engineering told me they were 13" sized and off an RSA Opel, he may have said which car but that was twenty plus years back and long forgotton.

I found a USA advert just now, Opel, Ascona and Kadett, plus others, we had both of those cars sold here late 70s I think?

Check the center caps :D now I know what I am looking for!

These Opel Kadett 13" rostyle rims will fit the Hillman Imp :)

I think the car is circa 1977?

Note, Chris Walters reversed the rim aka Lotus Cortina.

Please note, while the Opel is a German GM make, the wheel studs are Imperial and 4" pcd, the stud holes are larger than that of the Imps so an insert coller will be required to take up the slack.

Yes they are basically the same as our Vauxhall Chevette as they were called here, awful tinny cars about as basic as you could get the starter model.

Using a suction method and with my mouth I was able to hold the suction with my tounge for a good long while, I am now sure that the cars original vaent pipe has now leaks :)

Was there a petrol vapour leak at the petrol cap?

John Simister was sharp eyed enough to see that my cap as fitted was similar to his own and a center and side hole in the underside of the cap would release vapour.

An old cap and with the correct rubber gasket has now been fitted, will the smell stop?

A good idea just in from InfraZA and one which I will try today.

I have used a very heavy duty plastic bag and double skinned it too.

May I suggest you perform a test: In place of the cap stretch and secure something thin and petrol-resistant (e.g. intact rubber work gloves) over the opening and leave overnight/day. If the aroma is still noticed then the problem most likely lies elsewhere.

I find it difficult to understand how and why petrol vapour (i.e. smell) should escape the tank while the car is standing perfectly still and undisturbed while parked-up overnight – even if the cap gasket maintains a less than perfect seal.

I suspect there could be a very slight leak elsewhere in the system which is too little to make its presence known in anything but absolutely still air in your garage overnight……

Regards,

Rob

The vent pipe under the front wing is always open there's no valve or anything to prevent the smell coming out of the tank even with the cap all sealed.

No but the breather pipe is external to the cars compartments, it is also how I now intend pressurising the tank ( just a little) by fitting the correct cap and with a second rubber sealing cap I made yesterday.

By using a spare filler neck and a simple plastic bag closure, then by blowing on one of the two thin pipes while closing the other with my finger, showed me that the cap seal is good.

Today and after the car being closed up all night I still detect a light smell of petrol in the main cabin, so the leak is some other place?

The plan now is to jack up the car, disconnect the battery, remove the cover plate under the center of the car and gear shift tunnel, then apply some light air line pressure to the tank and then eye ball the fuel line back to the engine area.

What will I find, will The Nun be correct? :D

The tank pressure idea worked as far as testing for petrol leaks, excepting there were none to see :D

I had the small compressor set to a low output, I found out it was still on 1.5 bar so as much as 21 pounds, twice what was my intention and enough to raise the top of the petrol tank top surface some.

The only leak I found was air, that was via the petrol filler caps, as I tried the new and the old one, they were much the same in use.
The initial escape of air was nothing really, it was only as the air pressure built up that the air was escaping.

I used the tank vent pipe as the air line input, that worked a treat, simple to do and undo.

Check the tank lid, can you see it has raised some? I was able to push it back down and into shape again.

The rubber filler pipe and related tank hoses were quite air tight, so no fluid leaks there.

While under pressure I was able to take pictures of the tank exit pipe union,also the export drain plug under the car, there were no issues in either.

So there are no petrol leaks, not even when the tank and supply lines are under pressure, must be my sensitive nose?

For some reason I was never able to find the correct length front suspension bolts!

Fifty something years on and the petrol supply line looks rather good?

It is the one with the brass union in, the others are brake fluid and the new throttle cable (black) outer casing.

The petrol drain plug fitting was installed on cars known to be being exported so as to reduce the amount of petrol in the cars tank, safety issues etc.

Being what I would term the 'Wet' end of the car, the pipe has survived remarkably well, of course now I have wire brushed this front section up, I am tempted to get under the car and do some more now :)

The steel pipes do survive well on the IMP I think they were originally coated maybe a zinc of sorts, I dont think they are just bare steel? but the pipes do rust badly in time behind the rack mounting plate where they fester unseen and can get quite severely corroded, I seen cars pass an MOT only to have a pipe fail a short while afterwards due to corrosion that cant be seen properly unless the suspension is taken out of the car, a reason why just because a car has a recent MOT doesnt mean all is ok. :?

Another bad area for pipe corrosion is the brake pipe fitted to the top of the rear suspension arms, often buried in mud and the steel pipe clip doesnt help matters.

Yes, where you are and due to SALT? here we just get rain ( now and again) of course since the car came back to me I never drive on a wet road, well not this far.

I am now spray painting the area just cleaned and I need next to move into the tunnel area aft of the drain union.

In my case I do now know that the pipes and union are in sound condition, there was no rust to be found on any of the pipes which look as if they are plated, well they were once plated?

Working so far under the front of the car requires some thoughts and about personal safety.

After lifting the car up with the trolley jack I have placed an axle stand under each suspension arm, there are soft pads like carpet between the suspension and the axle stand to prevent paint damage.

The head lights are not on, it is the reflection from the sun as the garage door is open. :)

I went out for a drive, there was some slack in the clutch pedal, so not a full depression?

Not so sure as the gear shift was still good, clutch was working fine.

No change in the fluids level, what now?

There is free play in the pedal and before the clutch pressure starts, does it need bleeding, its never been touched since it all went back together .

This could mean that I get to fit the brand new clutch slave flexible hose that I bought some years back :D Imp027

This new hose was supplied by Bob of the Imp Club Spares department, I have had it here waiting for the time when I need to bleed the clutch system.
The hose on the car now is less than new but was what I had at the time.

Yesterdays work left a neat pile of dirt and dust on the garage floor, I used a cordless drill and some suitable wire brushes with a 1/4" drive shaft.
I was never really aware just how exposed the various fluid pipes are at the front of an Imp.
now to drop that cover plate then clean and paint inside there as well :)
