I had a similar one with the BX which turned out to be rust in a seam that had rotted and expanded the door seal. A new seal and some rust rectification resolved that one.
After leaving the car without its cover on overnight I can confirm the leaks I knew about seem to be fixed now. The problem is the leak I didn't know about: tailgate seal. The seal on the car is pretty flat and tired, adjusting the striker/latch won't help. Maestro uses a finned top seal (assume what's fitted is original) that's larger than anything I can find and I'd like to go a little larger than what's on the car because I suspect the measurements are squashed down a bit.
Here's a little diagram of what I'm after, with measurements. I've checked the usual places and while I can find top seals with and without fins, I can't find a finned top seal with these dimensions. Ideally, I want one that's ever so slightly bigger because I suspect the measurements I've got are on the small side of what should be there, due to squashage. The seal has a small fin on the top, and it also has a prominent ridge on one side, that's not a deformity of the seal, that's how it's actually shaped, and I can't find anything like that at all.
Tailgate Seal, Part number CKE10010, Rimmer Brothers £25.00 inc VAT in their clearance catalogue. Sorry rubbish with computers but if you google CKE10010, then look for Rimmer Bros. Then open the PDF. As for stock..............
I'm hitting a dead end on that one. I did find a forum posting that listed CKE10010 as the part number as well as the alternative part numbers of EAM9042 and ADL1771 so that's useful for future reference.
I also avoid shopping at Rimmer Brothers if I can help it due to their habit of applying VAT on top of the postage cost which I'm pretty sure is not how VAT works.
I did have a bit of a think about this water ingress issue and it's possible that it's not actually getting past the seal and is instead getting in through the wiper spindle or boot lock. I'll take the trim panel off when I next get opportunity and have a look, it will be easy enough to seal up if that is how it's getting in.
Nice to have principles re-VAT. I get that with Rimmers.
Think the wiring used to break to the tailgate, quite often bodged with crimps and heavily taped over resulting in the grommet not being fit for purpose or removed. Possible ingress route?
Good thinking re-wiper spindle they worked loose, took the paint off and the corrosion started.
Maestros used to be the pain of my life, my Dad bought three in total, all brand new, ran them hard until they clocked up some 100,000 plus miles, he then gave them to my wife as a present (worth nothing then as a px due to mileage) 100,000 miles was high then, any more was unknown territory that only Volvo could achieve. He knew I would say thanks for the generous offer but no thanks, he then went on and bought the next one.
The best of the three cars was the last one a 300,000 mile Turbo Diesel. Capable of a genuine 60 MPG. I actually regret the selling of that one! A true workhorse.
Each car was given a religious 5,000 mile oil change with Uniparts finest (Esso then) oil and a genuine filter. Zero engine problems in the two 1.3s or the 2.0 perkins. Oh happy days
Really, they're just very good at being An Car, maligned though they are. They're not going to set the world on fire, obviously, but if you just need something dependable to get you about then Maestros are still pretty good at that, in the 80s they were even better because they weren't all rotten yet. Mind you, the rot isn't anywhere near as bad on Maestros as it is on Montegos and really not that bad compared to contemporaries, I reckon we just remember the ropey ones because they just wouldn't die until they were completely toast.
Anyway, today was super parky outside so I had a crack at this leak hunting and little else. Failed to take any photos. Took the tailgate panel off and it's wet inside while the boot was basically dry except for a bit on the inside lip of the bottom of the tailgate. The wiper spindle area all looks dry, the water seems to be getting into the tailgate and draining out into the car, possibly through the rear window seal at the bottom where Maestros do tend to suffer from rust a bit. Considering how much wetter the inside of the tailgate and trim panel was than anything else, I suspect my issue is actually in the tailgate and it's just overflowing into the boot area, which means even if I had a really good tailgate seal it wouldn't make any difference.
So, I made a moisture membrane out of a binbag and some tape and we'll see how that does. I've got a feeling that's the wrong solution, the back of the trim panel has disentegrated foam tape on it that would have sealed against the tailgate and served as a moisture membrane, it also has vents in the trim panel which my new moisture membrane has effectively sealed up. I'll probably replace the foam tape with the butyl tape I've got left over and squidge some Arbomast into the tailgate window seal and that will probably fix the issue.
Happily, the front of the car is still bone dry so I think I've cured the water leak up front now. I doubt the videos on this particular adventure will do well, but hey, it's all part of old car ownership and care when you don't own a several hundred square feet workshop with lovely lighting.
Strange that you should mention the Montego, my Father-in law bought a brand new MG Montego 2.0 at the same time that my Father bought the Maestro Turbo Diesel. The Maestro as stated lasted many years, the Montego horrified us all as the back arches disappeared, the door bottoms bubbled away and it it was constantly being returned to the local dealer (Oliver Rix) to be sorted for water ingress issues (sunroof, windscreen x2, boot seal, drivers door seal, aerial and door membranes) How two cars from the same manufacturer can be so different is beyond me.
Good luck with the tailgate and the Arbomast, might also be worth squirting a little Dinitrol around once things are sealed? I watch with interest, nice to see one of these old girls still on the road, well done.
Oh and working outside is character building, story of my life
Just pump Arbomast under the seal all around the body, if you are able to get some between the glass and seal at the bottom it would be good but I doubt you will get the nozzle in.
On the Maestro it seems the front and rear (tailgate) screens are bonded and then the rubber seal you see is actually more like a flexible plastic trim. You can wiggle a screwdriver or similar under the seal, get the Arbomast nozzle in and then just pump goo into the void (careful) until you see it oozing out once full. Worked well up front, so the same treatment should fix the back, if that's the problem, which I hope it is because I'd quite like the water to stay on the outside now.
My mate is responsible for the 50mph zone on the bypass near Chesterfield College after he rolled his Maestro there into the opposite carriageway. He says he just held on and shut his eyes. When he opened them he had a lorry heading towards him and golf balls flying around the cabin as the glove box had popped open. Thankfully the lorry stopped and he wasn’t hurt. The Maestro not so much.
I had a Maestro van, with the 2.0 Perkins in it. Never did less than 50mpg no matter how hard I caned it. It was the “700” version though, with 14” rims, H/D tyres and heavy weight suspension. It rode ok loaded right up, but it was empty most of the time and it rode so hard the Land-Rover felt like a limo in comparison. I was glad to see the back of it to be quite honest. My sister had it for a couple of years, then a mate ran it for a couple more before passing it on again to another mate who ran it into the ground. Another mate of mine had a couple of Maestro turbos, which were genuinely properly quick cars. Their capabilities were greater than his though, as they both got written off.
My worst worry about dying is my wife selling my stuff for what I told her it cost...
My Father-in law bought an early MG Maestro, the one with the talking dash, the damp (sodden) interior killed the dash! Not a bad thing I suppose. Seem to remember it had twin webber carbs on it, it ran like a bag of spanners from cold and drank petrol like there was no tomorrow. The dealer never sorted them out (warranty) He still went on to buy two more Maestros, the good old days of being a Leyland man through and through.
One of my first lesson of cheap (Chinese) car parts was learnt on these also, Q drive CV joints, made of chocolate or similar I think, they lasted enough for the warranty to run out, very clever, the diesels had an appetite for them.
Sorry for the thread hijack, maybe set up a Maestro appreciation club
There is a Maestro appreciation club, I just don't want to commit to the level of club membership just yet as I'm still of a mind that I want this car to get me around while doing some small improvements to make it easier to sell on.
Speaking of, it wasn't fogged up today after last night's rain, which I thought meant the problem was solved. It isn't, but it is narrowed down a lot. Arbomast all the things was thwarted by the weather waiting until I'd got everything dry and ready to apply before bucketing down and not stopping until it was too cold and dark to do anything. I'll try again tomorrow.
Well, today for the first time there was no water in the Maestro. Have I solved the water ingress problem, or was there just not enough rain? Here's hoping for the former.
Youtube Info Might as well make a proper post about this. The text and picture updates will continue here but it will be alongside the video updates. There's a bit of a video backlog at the moment while I've been creating content to get the Youtube channel off the ground so there'll be a few weeks while everything synchs back up again. In reality, I'm about 2 months ahead of the video content at present.
Additionally, the Youtube channel won't always be car content, I'm going to be posting sewing and tailoring tutorials and info there too. I'm not interested in making a separate channel for each type of content, there's some skill crossover and it's good to experience and learn new things. If you don't want to watch sewing or cars, you don't have to, the thumbnails will tell you which is which.
Video updates will be a maxium of 1 per week, a minimum of 1 per month. The cars each have their individual playlists too so it's easy to focus in on whatever content you fancy.
There is an argument for doing things the Youtube way to maximise profits. I'm not that sort of content creator. I want to share information and encourage people to have a go at jobs that might be daunting. I want people to pursue whatever creative outlet they want to and feel no shame in it because they're not good enough, or it's a wo/man's thing. Gender is nonsense, do what you enjoy to the best of your abilities, sod what anyone else thinks about it.
I do aim to upload on Tuesdays, got caught out with internet speed issues on the last video which is why it went live on Wednesday, next upload I'll hopefully get it out on time since I have A Plan.
If you'd like to support my endeavours, please share the videos, like, comment, subscribe... you know all that stuff that costs nothing. I'm a small bean with less than 100 subscribers right now and that's fine, but it'd be great if I could get to 1000 by this time next year.
With time I will get better sound and lighting, maybe even a better camera. I've got more confidence talking to camera now but I still have a long way to go. Thank you to everyone that has been supportive of this venture. I'm not planning to set up a Patreon or that sort of thing, I don't want to get that involved just yet, we'll see how things go.
Been digging through my fabric and hardware supplies and I reckon I've enough stuff to put a muff together from leftovers. Had a look at the design of some other muffs and they look to be a very simple thing. The Maestro grille is a really simple shape so I just need to make a padded square, vinyl on the outside to keep the water out, a good thick cotton or canvas or something of that sort on the back to protect the paint on the grille, some padding between the layers to make it look nice and possibly give a bit more insulation against wind shear. Some eyelets on the corners so you can tie the muff to the grille and then an optional flap in the middle held in place with press studs (which I don't have) or really sturdy velcro (which I do).
It'll make for neat video since it's a good crossover of car and sewing stuff.
Reason for making this is that the car runs cold. I've ordered a new thermostat anyway, just in case it's that, but I suspect the tiny engine in the big engine bay and the colder weather just lately just means it's harder for the car to generate and hold on to the heat. A muff will help, and it'll be a fun project.
The problem with muffs is it is all to easy for them to overheat at higher speeds, not much of a problem on older cars they were vastly overcooled and probably only did 50mph but I would be concerned about something newer. If its all in good condition it should be hot enough even in this weather, our minor produces plenty of heat with a smaller engine in a fairly large engine bay.
As you suggest try the thermostat first, it might also be worth back flushing the heater if it's partially clogged the cold air will not be warmed up much even if the engine is getting up to temperature.
