While this car is far from finished, I am preparing parts for the next build. While I am in the mode and all. Spinning those jobs out makes it less of a drag. But meantime, just for something different, I washed it! Starting to look kinda tidy even... And last night I was messing around with replacing the lights inside the dashboard switches with LED's. The 5mm type are a perfect fit in the original lampholder, but I am still playing with resistor values to give me the level of brightness I desire. I sacrificed a switch body to become my assembly platform, as I have about 14 switches to do... When people see me with - or give me - another Marina, they say 'well you are the only person who can save it..' and I think, well that is hardly right, pretty well anybody who was interested could. But then I go to improve the look of parts that have been got at by previous owners - like the rear trim in the estate, and I think Jeez, who the hell else has these parts lurking in their shed.. Sigh. They do complete the picture of course, but I am surprised I would have ever considered I might find yet another estate. Or it might find me... I guess that is another thing off the constantly growing/receding list of stuff still to do. Pretty enthused with how it is all coming along overall though. Bordering on fun..

Back to the LED's. First trial run, albeit with blue LED as white have not yet arrived. I chose a 1K resistor which allows 8mA through the LED. They are most effective between 10-20mA but I do not want them too bright, and this current was measured at 12.5 volts, so assuming another couple of volts at full charge I have no worries about shortening the life of the LED's. The white ones may perform differently so I can trim their performance by altering the resistor value. The 'jig' worked well for assembly, and the LED framework was easily removable afterwards, so it can be inserted into a working switch unit. This bodes well as I have purchased 60 'warm white' LED's which should behave much as the incandescent lamps did. I cannot be sure how the luminance of the two types of LED will compare yet, but the blue one works well and does what is required of it. Should prove to be a maintenance free solution.

I’ve always had a soft spot for Marinas. Had a few back in the 80s and early 90s when they were plentiful and cheap. Getting rare now in the UK.

I originally swapped my first Marina for a used washing machine, after which I found that people were happy to give them to me for free if I happened to enquire what their status might be. I was already au fait with BMC technology, so it was impossible for me not to take advantage of this situation. I was not expecting the fleet to expand quite so rapidly, but I quickly discovered that the Mk3 versions were a bit more user friendly, and being newer, less neglected for as long, so I focused on these. Every car I scrapped was totally stripped before the body left, and now I am still using up those parts on every good body that comes my way. I have learned a lot in the process, but I doubt there will be anyone who really wants to know. I figure if I can prolong the life of more old cars I am helping the planet. I am also amusing myself. Like this. Today I received no less than 60 'warm white' LED's, so I checked the best resistor value for the amount of bright I wanted, and fitted one up. I am pleased that there is still a good amount of light which shines through the 'on' orange lens at the top of the switch, considering that LED's emit most of their light from the top of the capsule. Not so bright that it will be a nuisance at night... I am pleased mostly that the light quality is very much as it was with the original incandescent lamp. Time to ramp up the assembly line, as there are quite a few of these switches in a Marina. Pleasing exercise though. Cheers.

That's really neat. I should do something similar to the Niva, and sort the dash back lights in that and the T5 (vw not volvo sadly), and get working speakers in the van, and..., and..., and..., but I think you've at least inspired me to get the parts ordered for the Niva so I can get it back on the road for Xmas bumbling to the beach! Enjoying this very much.

On my MGB, I managed to find hornby trainset led bulbs that were a direct screw in replacement for the switch gear.

I figured there was a good chance an LED replacement for the original lamp might be available, but the lampholder was always part of the problem. On more than half the occasions I used to attempt to replace the lamps I would find they were still ok, but there was not enough preload to hold the base contact against the switch contact. Soldering the LED's should prevent all the problems. But there will be others....

I have a good line on 'warm white' LED's as it happens, and they are very bright.
Bear in mind that the resistor value should be 820 ohms, which limits the current through the LED to just under 10mA at 12.5 volts, so the LED should last forever even allowing for charging voltage to rise above 14 volts.
Ask me some other boring electrical questions... hahaha...

Obtaining a 'roadworthy', known in NZ as a 'warrant of fitness', is dependent on all of the vehicles original equipment operating correctly. However, it is not quite that straightforward. Seatbelts may now be rejected due to 'fading', as presumably fading may reduce the strength of the belt. Not that I have heard of such a thing ever taking place. In fact, I would dispute the fact that any seatbelt, used correctly, has ever failed in this country, let alone due to fading. External mirrors, which were an 'optional extra' in the day, are now considered de rigeur, so it would seem that 'optional' may now be considered 'mandatory'. It is a metal container of wriggly things. So. As the window washers at both ends of this car were not operative, it would be a necessity to make them be so. The front one simply did nothing, so I replaced it with the third candidate of all the old ones I had, and it immediately did the necessary thing. It actually washed the goddamned windscreen... The rear unit did actually run, but would not move any water. When I pulled it from its devious location I found the wiring was connected in reverse polarity, so the pump was running backwards. It would not run at all when connected correctly, even though I pulled the pump apart to check there were no foreign objects preventing it doing so. It had ceased voting for the right party. I found only one more of my used screen washer pump collection would run as intended, so I fitted it up and added water. Well bend me over and curse word me with a fish fork - it actually worked. If you will pardon the simile. 'I was relatively shocked' might be a more fitting pseudo. Anyway, that solved the last known issue between me and a 'wof'. While all this is rather tiring, considering the fact that I have now rebuilt virtually every single part of this car, I feel compelled to observe that the rear windscreen washer setup utilised on the Marina Estate was rather elegant. It has its own pump and reservoir, the latter being accommodated by the spare wheel cover, and thus both easy to access, yet totally concealed. You have to give it to the designer guys, they earned their keep. This seems to have completed the final mechanical hurdle between a static rebuild and an active and legal car. Presumably consulting the appropriate authorities will be the final test. Let us see what they say...

Well. They said this... Only comment was that the seat belts were a bit faded. Every thing worked as intended. So I whizzed over to my friendly exhaust guy.. And I have just now obtained 12 months rego online, and the label will be wending its merry way to me any old day. We are on the road folks.! Going to need another session of carb tuning now the gases can get out...

I have often wondered about the effectiveness of dying the belts. Obviously, life would not be worth living if her white jacket developed zebra stripes...
On the other hand. It has taken 38 years for the current belts to fade as they have. The next wof will be due in 6 months. I do not think I have any immediate problems seeing I passed this time...

Born of necessity with a smidge of self-preservation thrown in. Managed about 100Kms yesterday and defined a road speed rumble as spelling the death of the propshaft centre bearing. The propshaft was about the only original part left in the entire driveline. What was I thinking..? No great panic, as I have a couple of spares.. Swapped those this morning, only to later note that the replacement squeaks when reversing. Likely a universal has decided to become uni-directional instead. I shall let it develop for now. Amused myself between showers by touching up matte black wiper arms and grille insert.. The rear wiper got similar treatment, and I replaced the two tailgate badges. You can now see why the foglights had to go. The space is better occupied by the larger exhaust. Despite the gloomy freight predictions of up to ten weeks, my Chinese mirrors arrived in two. I hope to paint them body colour, so pleasing to find the entire glass and adjuster comes out by releasing two screws, and the alloy mounting also comes off by removing the screwed in pivot. They look as though they will work well enough in the original mounting location, so will hopefully cover all previous holes. Also appear to work well from drivers perspective. Although hard to appreciate from the photo, I think their shape will work as the previous ones did, although with an added bonus. You can actually see stuff in them... In other news, I revisited the carb tuning and achieved good results, so a bad hesitation from idle has gone. Takes an age to warm up, so I suspect the thermostat may have gone soggy. Oh well, another day tomorrow...

I rather like the black finish on the mirrors, goes well with the other trim ... eeeerrrmmm, can you do something with the cracked reversing light with the rusty screw please

I'm sure I can oblige with the rusty screw - given time - but I only have two sets of clear lens for these. They are 'sided', and I have one cracked left and one cracked right. Figures.
Trouble is, this car may end up with both the cracked ones...
Mind you, I am discovering forgotten treasures in the shed while hauling out all things Marina to complete this and one other build, so the game is not over...

The propshaft squeak in reverse quickly became a squeak in all directions that got louder with each mile. So - three propshafts in three days later we had a happy one. I now have one with a dud centre bearing and one with a dud rear universal. As the shafts are two piece and join aft of the centre bearing I can use the two good ends to make one good unit. That will be a save for someone, as the centre bearings are expensive now and their rubber housings are falling apart. The front seatbelts were proving to be a nuisance as they were reluctant to unlatch. The stalks were badly worn. I fitted another pair that I found to be excellent in their operation. Small things like this make all the difference to the overall impression of using the vehicle. The tailgate had a stupendous rattle. I had found both badges were loose and replaced them and their mountings, but it continued. I removed the trim panel and found the rear wiper motor was flapping about. The clamp was tight, but the motor was loose. The mounting plate had a depression beneath the motor that looked as if it may once have had some foam rubber. So I fitted some. Sweeeeet..! I decided to complete replacing the plastic trim panels there by doing the roof one, so while it was out I greased and oiled all the hinge mechanisms. One hinge was not fastened correctly as all the bolts were loose. Glad I looked. All came up nicely.. Having fitted a very bright LED lamp in the tailgate area it became necessary to make it turn off occasionally. I fitted one of these up front and they are amazing - not only super bright but no heat generated to ruin the covers. If you still have any... I found a suitable rubber boot to extend the switch button and it now does what it should. Another issue that had shown up, and which has plagued me on past Marinas, was the fuel cap. I needed to replace the locking/leaking one with a non-locking/non-leaking example. Extensive trials revealed that every locking and non-locking cap I had - and there are indeed many - leaked under the slightest provocation. Such as completing a left hand slide with a half tank of fuel. Or even just a spirited left turn. Fortunately I found one cap that has nothing whatsoever to do with a Marina, but does not leak a drop. Brilliant.! The original door mirrors I have are only a few years old, and are fairly faithful reproductions. However, I was wanting to try my new style Chinese sourced ones, as I did like the look of the body coloured items that were on the car when I got it. These could be painted, but I wanted to see how they looked in place. Hmmm. Not sure really. Would look quite different in 'jade green', but do they look right..? Jury still out. In order to run my Superlite wheels, the front guards have to be modified slightly to give more clearance at the front of the lower arch. Both the chin spoiler and the inner guard foul the tyre as it turns inward, because the offset is all outward, and the wheel performs a larger arc when turning because of this. In effect, this means that the wheelbase gets longer on the outside wheel and shorter on the inside wheel when turning. I have no idea what this does to the geometry, but the car feels far more stable with the wider wheels under all conditions, so I am not losing any sleep. This is one I just cut a bit off.. Fortunately none of this is visible from the outside of the car, so it matters not which wheels are on it after it has been modified. Now that I have done both sides, and rolled the top inner edge of the left rear guard, I can safely fit the Superlites and enjoy the look. The Marina rear axle is not completely central in the body, so the left rear Superlite will make contact with the top inner left guard if it is not altered in this way, but once again, the change is not visible from the outside. Everything else looks different though..! I would say - 'meaningful'... Cheers.
