Good Morning Gents,
Its Friday here so I'm happy.

Question:
Does anyone know what type of valve caps were fitted to Series 1 Shadows from the factory?

My car has this type, which has the valve tool on the end.
Looks ok, but not sure if it is correct.

Hi Richard,
Thanks for replying.
These are exactly the same type of caps my dad always ran on his cars for as long as I remember.
So your spot on about the era mate.

Little things like this are just impossible to find information on.
The build sheet does not show this kind of thing, and I don't remember reading anything about it on the chassis number/factory modifications over the life of the car since 65.

It reminds me of my search for the right washer bottle.
It seems they just fitted what Lucas had in stock that week.
I must have seen 20 different types of washer bottles fitted to series I cars.

Look at a "never used" spare wheel. This will tell you what valve cap were used.
The valve cap shown in your picture should have a small protective rubber tip cap over the valve tool part.

I don't think they were ever fitted at the factory.
Shadow 1s span a decade. I think most had the normal plastic types but have the feeling the early ones had the metal type used on Clouds.

Paul is absolutely correct. I have worked on Shadows since 1966

Good info gents.
Jonas,

You have now set me on a mission

At high speed centrifugal force can lift the valve. So for hooning around at 150mph one needs the brass ones with the wee rubber seal in the bottom. Or anodized aluminum ones for a bit of bling. RR or B logo as well.

Patrick,

the little rubber covers look like this




These are the real deal high quality caps from Schrader



They have the little air bleed dimple on the top, a rubber o-ring inside, and have Schrader printed on them. These are the RR of plastic valve caps.

Hi Ross,
That's great info.

I have never seen either of these.

Thanks for sharing.

I will start to look for the ones with the boots on them.

For the valve caps,these are the type on my Shadow 1 from new,Schrader is the name.

valve caps

The stove choke pipes for the operation should have the required heat resistant coverings.

stove pipes

On one of my 80s cars for the valve support for speeds up to 160 MPH the wheel has this support spot welded.

tubless valve support

Will do a picture of the 185 mph plus valve configuration when next down in the motor house.

That's fantastic info Pat.
Thanks for sharing.

The heat resistant material is interesting indeed.
I have not seen this on any Shadow before, as I guess it has just perished, or been blasted away by careless cleaning.
I know how hot it can get, I mean amazingly hot.

The valve caps are interesting indeed.
My 25 Chevrolet has the same caps.

Your last pic of the valve support is also new to me, never seen this before.

Patrick,

The original stove pipes on DRH14434 were insulated with woven asbestos fibre so take special care handling these items if this insulation is present on the pipes.

I had to make new pipes for the Corniche as the old ones had corroded and I purposely left them bare as I considered the insulation would only have been relevant in cold climates with sub-zero temperatures to keep warm-up times to a minimum.

I expect the US auto racing after-market suppliers would still stock suitable non-asbestos insulating sleeves/wraps for engine bay and exhaust system components.

The tyre valve caps were identical to those shown in Pat Lockyer's photograph.

That asbestos insulation looks kind of like spark plug insulation sleeve, but the above stuff comes in 10mm diameter and I think spark plug insulation comes in 13 or 14mm which would look saggy.

Hit it with a little VHT black header paint, bobs your uncle.

Ross

That's a really good find. I replaced the asbestos stove pipe sleeves on my car as they were worn and a bit powdery (using suitable safety precautions). I replaced them with the spark plug insulation sleeve which has been satisfactory and performed well, but this is much better. It's cheaper, has a higher temperature rating and also looks like the original woven asbestos sleeve. The perfect replacement.
