Re: SS1 CVH Silicone hoses

When my kevlar hoses failed at the beginning of the year, my original plan was to replace them with silicone, some from a Classic Silicone Hoses set - as my car is a late 1600, I wanted some of the hoses, but not all. When I contacted them, they were very friendly and initially eager to help, but when I said I only wanted to buy a part set, things rather stalled, and in the end I decided to sort it all myself, with standard hose sections. That's something worth bearing in mind, if you've got a late-type (lean-burn) engine.

Life's too short for hose joiners and extra clamps!

I can investigate comissioning a batch if you ate serious?
I'm interested if they'll fit a 1400 SST too.

I have a non-standard (polo) rad in two of my cars (snotty & G97) so it makes more sense than buying a bespoke set and modifying it.

I wonder if they were doing a batch, for they would make up part of a set at the same time? I found the same as Roger when I tried to buy a set but not have any heater hoses etc as I don't have a heater!

YES definitely. mine look like they are going to explode any minute. still all the originals and some have swollen to twice the size. i will have to take a picture of the engine so you know which ones it will take. mines an 88 ss1 1600. if you can email me through mendum-maintenance@hotmail.com that would be awesome. cheers, guy

Yes, mine's an '88 SS1 1600 too. So I'd think that, if yours is original, it will be the later lean-burn engine. It's easy to check - do you have a large diameter curving metal pipe next to the alternator, with three small-diameter pipe stubs on it? Do you have a water-heated autochoke? If so, it's a lean-burn engine. (I believe all 1400s were lean burn too, Ian (Mateybass), but I've no experience of them).

If that is the case, then the Classic Silicone Hoses kit won't be a straight-from-the-box, plug-and-play solution for all your hoses.

That doesn't mean that none of them will fit. I believe all the large pipes down the right-hand side of the engine are the same, and also the first pipe out of the radiator on the left. The others on the left will need a bit more work. There are a couple of solutions:

1. Make up your own custom pipes, for the remaining large pipes and the heater/autochoke pipes (and sell/throw away the ones from the set, that you don't use)

2. It has been said you can change the water pump to the early type, so you can use the early hoses (though you might still have to do something about the autochoke?). Presumably you'd then need to do a cambelt change (as I've always understood it's not good to disturb them part way through their life), also what about the engine/alternator mount?

hmmm. my car does have that pipe. dont really know if want to spend 300 quid and have to bodge it up. doesnt seem to be worth while. can you still buy all the original rubber hoses new? might look at going down that route if i cant get a full set of silicon hoses made to fit

Think it would be in the interest of a number of owners if we could get them to tool up for the later setup also. Waiting to hear back from my last enquiry.

I would certainly be interested if this can be achieved. During the winter check on my recently acquired '87 1600, I found that some of the hoses were showing distinct signs of their age. So I shall, of necessity, be getting some Kevlar replacements. Going by my experiences of Kevlar hoses on my SE6a, I wouldn't expect them to last more than 18 months.

hi. i have just got off the phone with the lady at classic silicon hoses. they said they can make up some tooling for the remainder of the hoses needed for the leanburn engines. they would require the old hoses to get the shapes and the diameter of the metal pipe bits which the hoses connect on to. they said they would need to make a batch of ten to make the tooling pay for itself though.

Liasing with CSH over this and should hopefully be looking to proceed with a new batch of silicone hoses in the near future.
I will of course push towards getting the later CVH setup catered for also. My question relating to this though, would be, are people looking for the water fed auto choke pipes to be reproduced in silicone also? This could add some complexity and cost, but I suspect "in for a penny in for a pound"

Now, does anyone have the variants of the later hoses avilable for the use of patterns? Otherwise I shall have to look at purchasing some, as those which I do have are so dreadfully past it, I would have my reservations about using them for patterns.

I only have some (not all) NOS early CVH hoses, sadly.

Formers already made for the early setup thanks to the initial work or Mr Faulkner.

Worth asking again, does anyone have the required later hoses as spares they could offer up for pattern purposes? Don't have to be watertight, just in the right shape!

Otherwise I shall have to track some new ones down for the purpose.
