Lurv your photo - a classic little car in front of a pair of classic 1930s garage doors.
Thanks Keith. Sadly, those doors are looking a bit rotten now (nearly as bad as the A40!) so I'll need to get a new set made up (in hardwood this time - so look out for for my kidney being auctioned on ebay!).

Scotty is planning a summer meeting at his race preparation premises near Newmarket and if you're within striking I strongly recommend a visit. (Google UCE 13 to get a glimpse of his very quick A40)
Sounds like a great day and a very generous offer. Wish I wasn't so far away. Will see how things go.

Do all MK2 A40s have these handy 'front tyre inspection hatches' under the headlights, or is mine just special? :D

I just applied a pretty advanced engineering technique to make the Austin at least 10% faster.

So, some progress on the car and some advice sought (for real this time).

Thanks to Derek for his fantastic help with the spares. I was able to fit new seals in the master cylinder and replace all the flexi hoses (two of which had collapsed internally). One of the solid brake lines was past saving, so I made up a new one (luckily it was the nice, short, easy one, RHF) so the car now has a brake pedal. I also 'Daz'd the fuel tank (thanks to Scotty for that!) and re-plumbed the replacement fuel pump that the previous owner had fitted for a temporary supply. So the car was ready for its first journey in my ownership. 20 feet up and down the drive.

Now, I knew I was buying something that would need a lot of welding, but was hoping it might be mechanically 'ok' at least, so I could knuckle down to fixing the rust.

Here are some observations, and please, if anyone can provide any input I'd be really grateful for some armchair diagnoses. The last time I owned a car with an A-series engine was back when I was 17. My first car was a very tired Austin 1300GT. Nothing since then, so I really know very little about these engines.

1) After fitting a new battery, the engine starts first turn of the key. With the bonnet up and listening from there, it sounds reasonably happy on tick-over and also when revved. A noticeable rattle from the front, I'm guessing this will be the timing chain in need of attention? I can't hear any knocking from the bottom end, but read on (if you wish/dare).

2) When I tried my little jaunt up and down the drive it felt like the engine was much more harsh from inside the car when revved (though okay at tick-over). It was as if the whole vehicle body was being rattled with it. I was worried at first that the engine has some deep down wear that I just couldn't hear from simply putting my head under the bonnet. But then I wondered if perhaps I've got some issues with the mounts (engine and transmission) which are transferring and amplifying the engine vibrations inside the car. Does anyone have experience of this kind of wear and how it might sound?

3) The clutch is very slow to engage. When you let the pedal up, there's a long wait as it gently engages. Once engaged it seems to provide drive okay and doesn't seem to be slipping (but haven't really had a chance to check it out that well). Certainly the slow engagement seems the most noticeable issue with it. You can let your foot fully off the pedal and then wait for it to engage. Maybe just needs a bit of use? Maybe the slave cylinder is sticking? The car has been stood a long time I believe.

4) When the engine has warmed up and the thermostat opens, water starts to pour out the radiator overflow. I'm guessing this could be a combination of a silted up bottom half of the radiator and bottom hose, plus maybe some damage to the radiator cap?

5) I've sat in the drivers seat several times since getting the car, but today, on the first powered trip we took together, all the seat webbing straps snapped and dumped my backside on the floor :( . This probably amplified the issue described in item 2 :) .

My main concern is item 2 - just how the engine sounded from inside the car when revved. I should add that the last time I drove something from the 60's was back in the 1990's, when I ran a series of Renault 8's and 10's as my daily drivers. But of course, these cars were thirty years younger at the time than the Austin is now, so maybe I'm expecting too much? But it's all I can refer to for comparison. They also had the engine in the back, which helps make it feel more 'remote' I guess? And lovely, squashy French seats of course :) . As I say, I'm just a bit concerned as to whether the harshness of the engine noise from inside the car is a pointer to some serious wear in the engine (not great when I really wanted to get on with the welding) or if maybe (hopefully) it just points to some goosed engine/transmission mounts?

If anyone has any pointers on any of these observations, I'd be really grateful for input. Thanks in advance!
And thanks again to Derek for the parts and Scotty for his posts about cleaning out a gummed-up fuel tank with Daz!

(PS - if you were thinking of giving me advice on item #5 - yes, I know, I should cut down on all the pies :) )

I know a lot of folks prefer standard wheels on their cars, but I think Rostyles look the dogs wotsits on an A40! 👍😎

It would be worth taking the radiator off and giving it and the engine a good flush through, and a good excuse to replace the hoses while your at it 👍

Yeah check engine and gearbox rubber mountings they can transfer noise as well as the exhaust mountings or the exhaust touching part of the body.

Water coming out of the overflow can be normal, does it stop and do you keep topping it up? If it's too full it will chuck it out until it finds it's own level, mine is well below the filler neck but works fine, it can't hurt to flush out the system. If you're worried you have an air lock I fill my rad and put the cap on then disconnect the highest heater hose(make sure heater tap is on, open) then pour water into the hose until it pours out of the heater tube and slide the pipe back on.
You could check the radiator cap does seal that would allow the water out.

On the slow clutch release it could a gummed up slave or master cylinder or so one has used oil instead of brake fluid. Reason I know that one is a seal went on mine years ago and I still had 120 miles to go so put engine oil in and the clutch worked, the only problem was I could take my foot off the clutch pedal and there was a delay before I started moving so I had think ahead trying to pull out in traffic. Luckily it was only for a day or so and I replaced the seals and fluid.
Stay Safe

Thanks for the replies guys.

You'll see there was slightly more to the cooling system issues in this thread > viewtopic.php?f=18&t=1941 (well - I made the job worse than it needed to be!). At the time I also removed the radiator and gave it a full flush (several times) and now it's all back together I'll flush the full system. Nice tip about using the heater top hose as a filling point Nik (I had wondered about jacking the front of the car up so the radiator would be the highest point :) ). And, yes, as suggested Clive, all the hoses need replacing (I'm part-way through them now).

The clutch issue turned out to be the pedal itself - seized on the common pin (brake pedal is free thankfully). As a quick fix I just loosened the nut on the end of the pin a bit so it can turn freely along with the pedal. I'll have a good go at un-seizing it later. With the pedal moving freely now, the clutch has a nice, progressive action and isn't slipping. So, I've found one thing that works (at last!).

Hi Dave, I can't say I'll be suggesting a meet up any time soon as my car won't be up to it for a long while yet :). But I'll keep an eye out for you if I'm round your way in any of my other old heaps :).
