Hi Mike
If you click on attachments, then click on add files. on my iPad you then have an option to take a photo or go into your photo library where you choose the picture you want which highlights it Then push Done. Once in the attachment you push lace in line then add you comment.
Lastly you push submit

Not sure if this helps or not

Just a little storey if I may. Micheal is quite right about the capillary tube being coiled imeadiately after leaving the head. My car was stolen in 1969 complete with coiled capillary tube & when I got it back the instrument panel with instruments was gone plus a few other bits. Fortunatley Lotus were able to supply the missing parts (except for the ammeter which had to come direct from Lucas). When I came to fit the new temp gauge I thought it a bit of a fag to try duplicating the coiling so I settled for a single two inch diameter loop. I ran it like that for the next eleven years and again from 1993 'till it finally expired some ten to fifteen years later so it really is just a question as to how much you want to stick to originality.

Paul:
Many thanks for your offer of help but to a complete IT amateur like I am, I regret I am none the wiser.
I need a guide in "Janet and John" language (that phrase in itself shows my age/ignorance!)
The picture I want to show currently sits in my "Pictures" file in my laptop. Now what?

Dave:
Thank you also for your support.....I thought it was just me on the capillary coils saga!

Apologies for this post getting so far off the original subject matter.

Michael - Assuming you know how to use email, send me the pic & I will post it, then reply to your email with a modern Posting for Dummies guide (with screen shots) for future reference. keith.p.halstead@gmail.com

Keith. Can I have a 'Posting for Dummies' guide too please?

No problem David.

Returning to the subject of capillary tube coils etc., for those of you who possess David Vizard's "Tuning Twin Cam Fords" there is a good picture on page 44 of that book showing what I meant, albeit with only one coil.
I used to have two or three coils and then the remainder of the capillary tube was clamped to the side of the engine bay before entering the bulkhead.
I hope that by now Paul has sorted out his overheating problems one way or another.

You should have practiced your new skills & posted it up Michael.

 

[David Baldock]

Come on Michael, get with it!

I don't have any pictures of mine in it's original state but I seem to remember three coils very neatly done. The capillary tube was then attached to the heater hose on it's way to the off side of the engine bay.

I could go on!

Thanks Keith for posting the photo which Michael was referencing. The capillary tube seems awfully close to the exhaust manifold, wondering whether it's best to begin the first coil a bit further away or would the capillary tubing not register heat at that point and only at the probe end?

 

[David Baldock]

Mine was coiled at the factory straight from the capillary. I've never had a problem with overheating.

I don't recall attaching the capillary tube to the heater hose.
My recollection is of using the plastic loom clips to secure the tube round the engine bay and having to route the tube behind the servo (for those with bulkhead mounted servos).
Like David, I never had any problems with overheating or false temperature readings etc.
With regards to my not practising my newly acquired skills in photo posting, I couldn't face the faff of having to copy Vizard's picture and then go through all the rigmarole so eloquently explained to me by Keith.
Yesterday it was me overheating rather than a Lotus Cortina.....today seems a tad cooler.

I'm hoping to add some pics. to this post showing the routing of my capillary tube. The thing is, that as the car was only three years old when I bought it, it was easy to see any changes that might have been made, so I'm confident that this is how the factory fitted them. The second picture shows the tube crossing from the heater pipe to the bulkhead.
The third picture is just me showing off my newly acquired arty smarty driving gloves. Back in the day I found them quite naff but now I feel they give me a bit of a feeling of "je ne sais quoi".
Please feel free to coment.

[David Baldock]

Wow! It worked but photo's 1 & 2 are the wrong way round.

 

[Michael Winstock]

David: nice pictures but surely your capillary routing cannot be right. The large rubber grommet in the bulkhead above the earthing strap is surely designed to accommodate the bulb and brass nut of the capillary assembly and your grommet appears to be empty!
On an otherwise lovely looking engine bay, why the black cam cover and why jubilee type clips on the coolant hoses? Personal choice....of course, but I thought you were a stickler for originality!

I hope the pics are where you want them now David - I'm glad the guide worked for you. Love the stringbacks. :wink:

Fixed.

I understand your pain Michael regarding the Faff. You would think that the bulb goes through that large hole, but I am reliably informed by my friend with the unmolested GBP 5C, that it goes through the hole close to the bulkhead plug. (No. 4 below)

 

[David Baldock]

Michael: You're quite right. My capillary was routed that way when I bought the car. As you can see from my picture the hole for the capillary is filled with a large washer and bolt which has always been there. The hole the capillary passes through never had a grommet fitted and the hole had clearly been crudely butchered to allow the capillary to pass through. I've always thought it odd but it has never really occured to me to look into it before. I shall have to decide now whether or not to correct it. Any opinions?

I've just read through the first paragraph and it occurs to me that the temp gauge must have been changed before I bought the car. It would never have been fitted that way at Cheshunt. So why, I ask myself, would anyone go to the trouble to neatly coil the capillary tube then change the routing and making a mess where it passes through the bulkhead?

Thank's to Keith for posting the picture showing and labelling the holes. That has enabled me to see how mine should be.

Regarding the black cam cover, the story is that when I bought the car I didn't know why the cam covers were painted blue. It didn't match anything else on the car. At that time the Lotus 49 GP car's cam covers were matt black so I copied that and thought it looked better, and I still do. I did always keep a bit of original blue paint behind the oil filler cap just in case I ever decided to revert.

Regarding jubilee clips. As with the cam cover they used jubillee clips on the 49 so I copied it. My conscience wouldn't let me change all clips so I still have the originals on the heater hoses at the bulkhead and the fuel filler pipe in the boot.

Finally, I feel I should apoligise to Paul if I have hi-jacked his post.
