Cool Runnings

It’s been some time since my last post, the problem being that I have retired or I’m between jobs one or the other and it seems that my time management is still in its infancy.

Original – New Core No.1 – New Core No.2

Nearly three years ago, I purchased a 1925 Lancia Lambda, from the first test drive it has run hot especially at speed, the radiator was an original one although probably not the original one, it wept from various places and showed evidence of many ad hoc repairs.  So after a trip or two to a recommended radiator man I had a shiny new radiator ….. the car still ran hot.  To cut a long story short after bringing the water pump back to standard spec, removing the head and applying a few pipes to relieve stream from pockets thitherto

New Core No.1, looks good but alas no

unknown.  The car still ran hot.  I had eliminated everything or so I thought.  As is so often the case the actual fault was found by accident.  While lamenting my plight over the phone to a fellow Lambda owner with both of us staring into our respective radiator cap openings it became apparent that my new core was very low on tubes, a very poor design in fact so poor it was no better than the original knackered one.  So today with the help of Jim the local radiator bloke who soldered in a tropical core I have reinstalled the radiator this one has staggered tubes and more fins ( 10 tubes per inch instead of 4 and 11 fins per inch where there was only 7).  It appears that my temperature gauge is now broken as it no longer moves, a much better problem to have.

Brackets ready for welding

The Bebe Peugeot has been languishing in a corner of the shed with a small list of to-dos standing in the way of the great open road.  For instance, the front mudguards mounts were completely wrong and very flimsy, the car was also missing the small “Modesty” panel that covers her back end and the clutch needed relining.  Luckily Bob had parts I could use as templates and as I was relining the clutch I could trade all the clutch parts he needs to duplicate for the parts I need to duplicate so for the last week I have been bending, grinding and welding while Bob has been turning good pieces of steel and bass into Bebe clutch parts and lots of swarf.

The Sizaire et Naudin is at last complete again after the front end was completely rebuilt, I’m just going over it so it’s ready for sale, having crossed Australia from west to east and from south to north it’s time for someone else to try another continent to cross or maybe Australia diagonally?

There is a sparkplug in that grass somewhere

Back in 2003 I bought a rough Traction Avant to participate in a 2CV Raid to central Australia this involved fitting a ID19 engine and 4 speed gearbox and apart from some roadside welding with some car batteries, the car went well on the Raid and subsequently went to Perth with no problems, however all good things usually come to an end and the poor old thing suffered the ignominy of returning home on a flatbed truck twice in the last few months.  First when a spark plug blew out of the head hit the bonnet and disappeared never to be found and second when the 3 of the 4 bolts holding the inner driveshaft flange on fell off again never to be found.  Nothing that good maintenance by yours truly would have prevented.

On Bentley tuning, Sizaire axles and Lambda Head Gaskets

IMG_1696First up Des has just added 1.9 litres to his 3 Litre Bentley all done very nicely by Up the Creek Workshop the car is now quite a weapon, however it was running a bit rich.  Most of us would at this point start randomly stuffing around with different needles for the SUs, this is where Des’s engineering background makes this a bit more like science.

If you look at Des’s photo on the left you will see the laptop is connected to a camera looking into the inlet of the SU, to the right the 10.3 is my air/fuel gauge temporally lashed to the dash and the gauge above the red lamp is the tacho.  The readings in the pic were just in neutral however the next day   it was repeated  on a long hill,  so with some measured guestimation new needles were ordered and it’s now running around 13:1 throughout the rev range, so all those gadgets have at last come in useful.

The Sizaire Naudin has now been off the road for 18 months waiting for a new front axle to be cast after the old one was found to be cracked.  Alas after receiving the new one (and a spare luckily) it was found to have a warped spring pedestal so back it goes, hopefully the spare can be used as I don’t fancy waiting another 18 months.

IMG_0975 (1)The Lambda has been up to UTCW for some fettling before its holiday to Europe, as with so many jobs the list started small with reset the rear springs, check the brakes and the front wheel bearings. The springs were reset but the rear hubs were shot as were the rear wheel bearings and seals but the brakes and the front wheel bearings were fine so sort of equalled out.  But there was a niggling problem of running hot at speed and this would need the head removed.  Now any Lambda owner will tell you if you do not have a blown head gasket leave it alone, removing the head usually exposes the sorry state of an aluminium block in its final stages of decay but I just had to know.

The picture on left  shows my rather unique block which is not too bad for a Lambda although a bit of a shock was the size of the bores as they have been sleeved down to make good some previously dodgy machining making my car the smallest capacity Lambda in existence. On the bright side it shouldn’t break a crank as overstressed it isn’t.

Lastly, I’ve stymied some oil leaks on le Bébé but I am struggling with my bargain Zenith carburettor that has the engine idling at slightly less than flat out, the throttle butterfly is a bit of a square peg in a round hole so that may be the problem.  Once the Lambda is on the boat I’ll get back to this one.

I wonder what normal people do with their spare time?

 

Getting hot and cracking up

Busy week, first off the Bebe Radiator was sent to Fluid Dynamics in Hallam to go through their ultrasonic cleaning process, next the water pump went to Colin to see if any magic could happen with it as on inspection it seemed OK but was not following it’s job description.
Two days later the radiator is back, another day and the water pump is back with a re-profiled impeller, mainly Colin removed the fins from the centre so it now looks like the one in the parts book, whether this is better or worse only a drive on a hot day will decide.
Taken with Nexus 6, Android 6.0Here is a thermal image of the radiator after idling for a bit, I should have put something behind the radiator as you can see the heat from the exhaust. But you can see the heat going from the top and down the LHS of the picture then cooling as it goes toward the right.

While having a nice lunch last Thursday, David R. suggested that as the car has a very low compression ratio, a relatively long stroke and is using modern fuel, a static advance of at least 35° would be a good place to start, so 35° it is and it certainly sounds better.

Unfortunately Vicroads has lost my Club permit application so no test drives yet. Update! Vicroads now state they sent the plates five days ago which is very unlikely as yesterday the Peugeot could not be found in their system, blaming the postal service is easier than telling the truth I suppose.
Good news on the Sizaire et Naudin front, after many attempts a new front axle has been cast and a second one is on the way just in case. I have attached a photo of one of the steering balls that failed the crack test so Colin put it in the vice and as you do …whacked it with a lump of wood.  It broke like a dry twig in a completely different place than indicated by the crack test. Hmm what are the other 3 that passed like? Colin is now making three more new ones, better safe than sorry although more of a worry in old cars that go fast.
