My First Renault 4 - External Combustion Engine

Fuel pump replaced with cleaned and checked used original spare, and all is now well :).

We took the old pump apart and found that the oil seal on the diaphragm shaft had failed and oil had filled the chamber effectively hydrolocking the pump, hence the oil slick in the picture below. Originally we suspected the diaphragm may have perished due to ethanol though this was not the case.

Unfortunately the rest of the pumps components are in perfect condition but is unusable.

Parts are rather unnervingly aligned with the newspaper photo person. I gather he's one of these "ballfoot" types, or whatever they're called.
 
what an amazing feat, looking forward to the final piece. you make everything look so possible!! what coats of paint did you use for the interior and exterior protection coating? I'm planning an attempt to tackle rusts on my R4, would appreciate it if you can provide some recommendations, tips, and items/products used before I proceed.

Many thanks :)

For products Wurth red oxide Rust-Stop, and for the paint two-pack primer then two-pack top coat is what was used on my car.
As for tips look on the forum at restorations and you'll find the common places 4's rust and it's likely someone will have shown how they repaired it. Getting rid of all rust as well as possible before making it look pretty is the best way to go, but you may be in for the long haul depending on your starting point.

Hope all goes well with your resto !
 
It's been over a year since my last post and not much has occured with the 4 as university has taken over and the car has been safely locked up at home and only regular services have been performed as needed and the car has been largely trouble free!

The only troubles that had occurred were as a result of the throttle lever plate being worn as pictured below. The wear in the hole for the throttle return spring cause the plate to stress and cut through two of the springs, snapping the hooked section and slamming the throttle wide open in the process.

The first time this happened the car was moving on a narrow back road which was an interesting experience :o , and the second when in a petrol station giving me some eye rolls from onlookers - luckily the spring was able to be bent around the hole enough to get home and replace it.

Now as I'm visiting my dad, at Renospeed in Devon, it is a good idea to replace lever with a less worn piece for the journey home.
On a better note my car performed perfectly on the way up to Devon with 277 miles covered in 4Hr 40m and achieving 44 MPG with my normal driving style at that, leaving us only mildly deafened in the process...all a bit of a blessing with current fuel prices :laughing:!

Future plans for the Yellow Terror have no set date yet, but beefing up the suspension all round and particularly at the rear is first on the list as it has gotten particularly soft within the 13,000 miles driven since the restoration.

Next destination Beaulieu Simply French...
 
Hi all, I haven't posted in a long time; this is largely due to the fact that my yellow 4 has been performing and running perfectly. After the past few years, my 4 has helped me move student accommodations four times and done multiple 500-mile roundtrips with no problems whatsoever; snow, sun, and occasionally being laid up for a month or two without starting. My little 4 has been as reliable as can be. My lack of posting is a result of simply having nothing to report. I have now done just over 20,000 miles since restoring the vehicle 5ish years ago!

However, in late October, after moving back home from university and a routine service, I had a fire start under the bonnet :flame:. After meeting a friend at the pub, my car died at a set of traffic lights—much like I had pulled the choke out completely. At which point black smoke plummed from the bonnet, and the paint started bubbling up. I shut off the ignition and rolled the vehicle to a safe spot. In the space of about 20 seconds, I lifted the bonnet, which caused the flames to nearly take off my eyebrows as they rose about 4 feet in the air, with no way to extinguish them. Fortunately, at this moment, an elderly lady pulled up the side road and stopped. I ran and asked if she had any water. Thanking my lucky stars, she was carrying a 2-litre flask of cold water! I doused the flames and put the fire out. I will never be able to thank her enough!!
To shorten a long story, the lady drove off after offering me a lift. I went into the neighbouring kebab shop to ask for more water to put out the smouldering and glowing rubber hoses. The billowing smoke actually set someone's home smoke alarm off :laughing:. Fortunately, to my eye, the damage did not seem too severe: the loom was still intact, and the fuel pipe was charred but had not burnt through; even my air horns hadn't melted. Unfortunately, what ensued was a 4-HOUR WAIT to have the car recovered half a mile up to my home, as I had no way other than to abandon my car. Of course this had to happen at midnight when all shops are shut, on a very cold night at that. So after assessing the damage and finally finding an extortionate recovery service after literal hours on the phone to useless recovery services, we finally got the car home at 04:00, after 4 hours sitting in the freezing cold staring at my burnt pride and joy!

Note: the lifted paint in pic1. The camera flash in the second picture does the visual a favour; it looked worse in person. Also note the brand new air filter now waterlogged and melted.

Me and my dad (Mr. Renospeed), with helpful assistance from @Cornish4 , trailered the car down to Devon to assess and repair the damage. Luckily, the first predictions were correct, and the main damage was the bonnet. The wiring loom, important hoses, and cables were thankfully intact. There was no water ingress into the combustion chambers either.
We stripped the carburettor in situ and found that the float ''bridge'' had broken, thus causing the float to drop and the bowl to fill with petrol, and under pressure, spray fuel out of the carburettor seals, like an overflowing toilet cistern. Pure bad luck! So, the repair was in actuality quite simple—replace the float bridge, fuel pipe, breather hoses, air filter, windscreen washer hose, and vacuum advance tube. Additionally, the oil temperature sensor needed replacing; even though there was no visual damage, the warning light was stuck on. Despite the tip of the air box being charred like a flame thrower, the internals of the carburettor and inner-wings were un-affected.

Note: the broken float bridge and how the bonnet brace took most of the impact from the fire, saving more of the paint and stopping the bonnet from warping.

As a temporary measure to preserve the bonnet, I sanded smooth the damaged area, and then we applied red oxide and colour-match yellow paint. This will remain until the new year, when the bonnet can be fully resprayed. We also gave the engine a coolant refresh and gave the engine bay a good clean. The paint isn't perfect, but it will make do until a better job can be done. The plan is to tackle the paint work on the bonnet and air box and replace both nearside wheel bearings as they have begun to grumble.

Moral of the story... well... when your mind is telling you a couple of days before disaster that ''you should really get a fire extinguisher just in case'', TRUST YOUR INSTINCTS!
In seriousness, however, both me and my 4 were extremely fortunate that this fire happened in the way that it did. Had the scenario been different, my car may not have survived and I might have been injured. And that thanks to strangers and friends, I was able to avoid disaster.

My car is back up and running, performing just as well as it always has! I have ordered a fire extinguisher; more updates shall follow...

Glad you and the car are OK, mine did a similar thing whilst cold starting, without the fire bit , i do feel your pain.

Does anyone have any recommendations for which fire extinguishers are good ones? I feel I should have one in my pair of old cars too.
 
I've just ordered a small Firexo one. No idea if it's any good, but it does work on all types of fire.
 
Glad you and the car are OK, mine did a similar thing whilst cold starting, without the fire bit , i do feel your pain.
We have noticed a few plastic components having age related failure lately. Which is irritating but fair, considering a lot are at least 40 years old...

That is likely the exact one that I now have haha.

Thank you everyone for your reponses too! :laughing:
 
I'm glad to hear you got it all sorted in the end Harry, and happy I was able to help with the recovery to Devon.
This is the extinguisher in my car, which I've mounted on the chassis cross member under the passenger seat for easy access. I've a second smaller one as backup in the passenger door pocket. Don't be tempted to keep it in the boot, where it can get buried up and possibly damaged.
Happy motoring, and look forward to catching up with you in the near future.
Regards Bry.
