- I wasn't sure if this should go in Classic Fibreglass or Classics and Heroes. Maybe the Mods can decide -..

Go back to the mid 1970s, I'm the proud owner of an MG Midget or maybe a Hillman Imp. I'd drive every day, up the A1058 Coast Road from Tynemouth to Newcastle for work. Nearly every day I'd see, and often get passed by a green Gilbern Invader Mark 3. I loved the look of that car.
Turned out it was owned by a fellow car enthusiast called Tony who lived not far from me. I used to bump into him in later years and have a chat.

Jump forward now to 2023. I'd moved around quite a bit and now live in Scotland. A pal points out that there's an advert for a Gilbern in Tynemouth. It's the same car and very sadly Tony has passed away. He'd owned the car for 48 years. He'd pampered it, modified it, it had been his hobby, his passion.

You can guess what's coming next. A 500 mile round trip to view it, a slightly hiccuppy test ride as the car having mostly stood for a few years with limited mileage wasn't quite on song, a long and protracted, head v heart discussion with myself, an offer and the car was mine!

Money paid, transport arranged, it arrived at my home a few of days later. Of course it wouldn't start and we had to push it into the garage. And there it languishes at the moment. It's not a standard set up, Three Jenvey down draughts, Emerald management set up and a lot of wiring and plumbing for a guy who is more "carbs and dizzies" (me). I'm working from basics as there's an electrical fault somewhere with power not getting to where it should, it's a project, it needs a new headlining and the interior retrimming etc, once I get it started that is. But that car that I so admired nearly 50 years ago is now mine. It'll always be known as Tony's Gilbern however....RIP Tony, I'll try to look after it.

Watching with interest (book marked), only ever seen a few (Car shows etc) and only one on the black stuff. Best of luck a terrific little car. I will did out my on four wheels encyclopaedia set and read more on the car. Was there a 3 litre and a 1.8 versions?

Lovely story and Tony would be very happy it’s now with a fellow enthusiast.

Emerald are based in Watton, Norfolk, about half an hour from me, but a long way from yourself! But tracking down their phone number will not be difficult and I'm sure they will be able to point you in the right direction regarding their ECU. The gaffer used, perhaps still does, write for PPC magazine.

Nice looking motor, trust you will enjoy playing with it.

Wonderful story - I always like a tale where someone tracks down a car they knew back in the mists of time. Bravo and good luck with getting it roadworthy for the summer.

I used to pass a Gilbern Invader every day on the way to work, during COVID it left and I feared the worst for the old boy, but the next week there was an MGB V8 on the drive. He said someone made him an offer he couln't refuse, and after 12 years he wanted something roadworthy!

We are but mere custodians of the things we have.
What a great story and always nice to see things go to good home.

This thread definitely needs more images...

lovely thing. I always thought these things were a great design that looked current for a long time. There used to be one parked near me when I grew up.

Thanks for the comments, more photos will be put up once I get it started and running.
Here's one I took yesterday of the engine bay. Suggestions for a simpler plenum/filter are welcome. You can't do a simple flat based box as the fuel rails are higher then the throttle bodies. But I need to get it running first.

I can see why it doesn't start, battery is missing...😁😁

Bookmarked, hope you manage to get this going.

Re the intake perhaps have a look at the rocketeer. I'm not suggesting carbon fibre but they have a nice compact design.

The current one looks like it has a high probability of air leaks and a laggy throttle response.

Completely a must follow thread. I’m sure you’ll have grabbed the attention of all motoring enthusiasts (with petrol running through their veins) at the mention of Gilbern!

The history will make this so much more interesting, filled with memories and dreams. Perhaps one day I’ll find that Alvis TE21 someone used to daily on the A46 25 years ago?

As the car was previously running but lumpy I'd start by replacing the fuel filter and work from there. Often a problem area if a car's been left standing.

I'd also drain the old fuel (not clamp the line) while doing the filter and get some fresh petrol in there. If the old fuel looks OK when it's settled I'd eventually put it back in the tank (or your mower) a bit at a time so that it's blended with fresh. If the fuel's full of rust you'll probably be looking for a new fuel tank or proper refurb.

That's the plan once I get it started.
Now have power to the ignition switch and it'll either spin over and try and start or blow a 30A fuse. The tacho seems to suddenly jump to 2K revs and stop there until ignition totally off. Plugs out now, soaking wet iridium ones.
Not raining today so got on with paving outside, back on the Gilbern tomorrow.

An update, a little longer since the original postfor which I apologise.
(New fence, paving, and countless other little tasks to sort but I have been busy).

Firstly, thanks to the folk who offered knowledge and enthusiast in the "Engine & Transmission" pages. The info and advice they offered was invaluable. I now know a heck of a lot more about ECUs, throttle bodies and fuel Injection, fuel line fittings and filters. I was a PITA over there but hey saw me through it.

So where were we. I got the car into the garage and spent an age trying to understand what was going on. A broken wire, a duff fuse, a second fuse blew straight away which was worrying and a set of iridium spark plugs that went in the bin. Apparently once they are wet due to flooding they're as good as knackered. Cleaning with a wire brush is the final coffin nail. New set of BP6ES fitted (have you tried buying spark plugs these days? Local shop had 4. Asked about BP7ES they had three! Halfords may stock them but that reference is a "Lawnmower plug". Fortunately Burton Power keep them even if you have to pay rather a lot in postage.

The result: it runs and sounds sweet. Oil pressure good too. So what next. Well I wasn't happy with either the feeds to the 3 throttle bodies nor the air filter arrangements. These weren't exactly applauded on the Engine pages either.




Tony was a first class Engineer and I could see exactly why he had done what he had done but it wasn't the best. Everything was in the way of the spark plugs and even the dip stick was difficult to access. I don't like braided hoses as you can't see what's underneath, even more so with the heat shielding in place so out that all came and fresh R9 fuel hose and good old fashioned "T"s and hose clips realigned the fuel feeds alongside the throttle bodies. Tony was concerned about heat build up under the bonnet, I'll have to see if that's a problem up here in Scotland.
Air filter wise, I'm still not sure, there's very limited room and the rear TB sits almost under the bulkhead. I have as Baldrick said, a plan. It's about Plan D or E, A, B & C having already been dropped.

So out the garage it came this afternoon for a couple of photos. I think I may have a fuel leak from the LH tank area, there's two tanks, one in each rear wing. Further investigations shortly after I finish the fuel hoses and air filers in the engine bay. Then it's onto the interior. Headlining if 50 years old and won't see 51. There's a couple of side panels to redo and maybe replace the carpet. The wood dash will look bad once everything else is sorted so that's another project. Fortunately the front seats (MX5) are perfect except sitting too high and the rear seats were retrimmed in leather to match the fronts. MX5 seats are wonderful, comfortable and supportive, I had them in my TVR Chimaera. The problem with them is they tend to sit high in either car. On the Gilbern the problem is compounded by stuff under the seats (Emerald ECU on one side and a brake balance adjuster on the driver side).




Curiously for those who have got this far, Tony & I have the same christian name and even our surnames start with the same letter H, sadly the registration bears no obvious link to either of us.

The good and the bad today.
First the good: the revised fuel to the TBs

And the bad: investigated a fuel leak at the rear. All connections tight, spot a fuel drip from the LH drain plug. Literally touch it with a spanner, no attempt to turn it and:

Followed by 5 or 6 gallon of 99RON E5 making a sharp exit and me scurrying round looking for containers....

Well I'm still trying to decide on the best method of attaching air filters i the very limited space I have and also waiting for the postie to drop off some Loctite 243 to make sure the fuel tank drain plug stays plugged so yesterday and this afternoon I set to with the interior.

The seats have all been retrimmed by the late departed previous owner and look fine. The fronts are MX5 replacements and the rears are the original under the new covering.

The headlining however is in tatters and is to be replaced, so I first removed the sun roof and side rails.


Then the seats came out. These need modification as they seem to be high even for a sub 6 footer like myself. They've got beautifully made subframes but I'm going to have to redo them. Tony must have been a damn good welder of aluminium unless he subbied it out.



Under the seats sit one one side the Emerald ECU and the other side is the home for a brake balance kit. With upgraded brakes front & rear I guess that may be needed. Lowering the seats will compromise access to both but that's the price I'll have to pay.

Carpets are a horrible interwoven carpet material but are not worn so I'm not sure whether to recarpet or leave but maybe try to recolour? Not sure I like the green.

Speaking of green, the side panels in the rear are or rather were a bright green velour which has faded and dirtied over the last 50 years. I toyed with the idea of just recolouring but decided to replace. U fortunately the retractable bit of the front seat belts is bolted through the middle of them. Drivers side unbolted easily. Passenger side wouldn't budge, should I go back to the recolour plan, no let's get the damn thing off. It's only a bolt.

Sometimes I don't know my own strength.

Left the garage on a bit of a low.....

Oh dear!

That is going to take some shifting.
I would centre punch as near centre as possible, then drill through with a small drill, increase the size of dril until either all out or the remains heat up enough to free off and will wind out. With either option, it's a bd of a job.

I've always loved the MK3 Invader after my dad had one back in the 70's and 80's

4 drill bits in and not at the full depth of the bolt yet, did increase bit size as I went though. One bit slowly blunted and started to glow red so I kept on going and the bolt became cherry red too, all in the hope that the heat would help. Release fluid too inc a special one provided by a supplier to the trade which I'll keep dowsing the bolt with. Had a hammer and chisel (screwdriver) at it too in an attempt to start it off but it ain't shifting.
Beginning to wonder if it was the right bolt and it's cross threaded as well as rusted?
Patience, Patience, Patience.

I have only had to do this once, on a caliper bolt at that. The third increase in size saw the bolt remains colapse as I had failed to centre punch in the centre and the remains wound out. But I had the advantage of being able to clamp the caliper carrier in my bench vice!

I guess that you cannot get behind the offender?
Would you be able to Dremil a slot across it, to give your....hopefully old....screwdriver something to dig in to?
