Would some sort of a VW part work? Even if it means replacing the matrix with VW one? 

Sadly I'm stuck with the original BLARG setup.

I replaced the ruined matrix I found not long after buying the car last year. Wasn't a cheap item either. So I don't want to do away with it.

These buggers are the major issue. They rust out and pin hole randomly.

I got these ones a while back as another set to have. These are rotted out in places too. However I may look at repairing these or use as a template for making a set.

There was stainless ones made years ago through the FB owners club. Sadly they were group buy only. So not something I can easily buy.

Annoyingly. I could of got a matrix with the hose tails instead of the the flange from the same seller. I should of got that instead.

That's got to be a chemical metal job surely. Much easier than trying to repair with a heat producing process!

You'd have been either proud or disgusted at the amount of chemy metal I had used 😆.

It's probably fixable with some more or I'll have to quickly learn how to braze stuff.

This may sound silly but can you not do something with fuel hose?

The context is that our series Land Rover project uses fuel hose to connect to the heater. It essentially has stubs of hard line at each end (engine and the heater itself) with just big thick fuel hose connecting it all together. Held on with jubilee clips.

Admittedly the stubs at each end are flared, so that might be challenging to replicate.

Posted

It is an idea.

Something I may look at. As these pipes join at the bulkhead. Could bridge those with hose joiners then rubber pipe to the remains of the metal pipes which then bolts to the matrix.

Be a case of making something with a barb end to fit the remains. 

Tried joining the previous damaged section with heater hose. Kinda worked, but the jubilees ended up crushing the pipe and I had a small drip.

If the flange that attaches to the matrix is sound, then cut the pipes back to a couple of inches long and do the rest with heater hose.  If the hose fits properly and is well clamped it doesn't really need flared ends to the pipes.  If the pipes are rotten where they enter the flange it wouldn't be difficult to braze some new bits in.  Could do it for you but I don't think you are local..

I'm just about in the middle of nae where. Thank you for the offer though.

I had a look at my spare set of pipes. I've manged to separate the pipes from the mounting flange without much hassle. Also remembered I have a load of 15mm copper pipe from a DIY job ages ago and some Yorkshire fittings with a near enough bend to work. Nowt to lose by having a go at making a set.

Bon chance, I'd be interested in how this pans out as no doubt mine are fucked too. 

I did manage to get a matrix (I think from that guy who was selling loads of Maestro bits) as they too are NLA. 

In that picture above of the pipes, does the long bit with the flat flange go inside the cabin?

Sorry daft question time!

This bit?

Or this bit?

The Maestro/Montegos are one of the easiest cars I've replaced a matrix on. Once the glovebox is out of the road you can access it all

The bottom pic. Is that what mates with the matrix inside the cabin?

Yep that's it. Three Allen headed screws holds it on. Be careful they are a pain for chewing up the internal hex so be sure the key is fully seated into the screw first. I use a key with a ball end, once they are all cracked off they come out pretty quickly by switching to the other end. Think it's a 4mm hex if I remember right?

There is a rubber gasket that sits in-between the two. Have guess how availability is for those.... 

Or they did use o-rings in the past. So you could possibly go with that.

I shall share my effort/failure with making new pipes on here.

As an aside, is chemical metal the same sort of thing as JB Weld? 

On the subject of rusty pipes, I did these support/transfer bits and pieces on my Maestro in high temp paint. Black would have been better but I already had a tin of blue open.

The upright struts support the manifolds and the crossways one is a coolant pipe. I chose high temp as it's pretty close to the zorst...

Yeah, JB weld and Chemical metal are pretty much the same two part epoxy goo.

Not a bad shout painting that coolant pipe. As it might be another one that's not easily replaceable.

Found the leak. A pin hole, blobbed some weld in and smeared some more chemy metal on. Ran for a good while leak stopped.

At this rate I could do a reasonably good job of icing cakes! 😆 

Then a picture for @grogee of the pipes in situ.

I have made my other set up now. I just need to figure out a method of attaching the mating flange to them. Did buy some brazing rods from Halfords. They weren't very good. I'll sort something out another day, as these ones are holding up for now. 

I was also helping a fella with some welding on his MK2 Golf. Wasn't pretty but it'll do. Never took any photos of this.

WELD one JMotor! Is it back on the road?

If I didn't have to head home sharp it would of been. 

If everything works out as it should. Maestro back to daily duties this next week. Altezza back inside and do it's tension rod bushes and back to the Opel for rust repair.

I went through similar shenanigans with the Senators matrix pipes a couple of years ago. Replacements unavailable. After some discussion on here, this was my fix:

So far so good🤞

Surprised to hear that. Never thought Sennys had that bother? But I'm not in that circle of cars. 

But that fix looks good.

I tried the exact same. Mine leaked for some reason. 

Then thinking about it. These current pipes on the Maestro really are on borrowed time. I'm on the second tin of goo now! 😆

Yes, mine is a non air con equipped model, so quite rare. Easier to find pipes for air con models. I tried everything you’ve tried, before resorting to this. I tried two pack goo too, without success so I wish you luck. Also tried braising and solder but the pipe melted before the rod/solder🤷🏻‍♂️

Ah! Wasn't aware of a non-ac cars. 

Found the same with making replica pipes in copper. Pain in the arse. But I'm a complete noob and impatient as, not a good combo when it comes to soldering. 

I was able to weld mine due to them being steel. But I always got a leak from a missed bit. So the goo was a back up to my efforts.

I think in these situations. What ever works, works. I've stopped questioning it now as you can't argue with results.

Usual craic though isn't it. It's not a bodge if it works. Said with a completely straight face. I mean what's the option? Scrap the car cos of leaky matrix pipework?

Exactly, but I must give credit to @danthecapriman who I think suggested this as a resolution to my problem. The Senator lives on as a result and should get an MOT pass this week, hopefully.

These never come up for sale, I saw it for a fiver and grabbed it. I'll be taking some measurements so we can have a go at making our own Blue Peter ones.

Handy and quite a lucky find that.

The metal parts look easy enough to replicate. Just be finding/making a bush to go in the tricker bit?

Small update time. Maestro is back together and appears to be holding coolant again. Back to daily duties.

Took me a short while to mop up in behind the dash as everything got a soaking when the pipe let go. 

Hate coolant as it doesn't actually fully dry out. Carpets may have to come out at some point to clean them as a bit got soaked in.
