With cylinder number one having a similar compression to the rebuilt engine in the car now, I thought that I was ok with the compression on the old engine as removed.
That was not the case as each cylinder from number two to number four read less and less compression, I wonder why this is the case?

John,

I wonder as that would be the cause of the decline almost wedge shape fall in compression?

I also added a petrol and engine oil mix from the number one cylinder, it was a while before I tested the compression.

What I can do is re charge the battery, its a big one from a Golf Cart I think? Then do the oil mix addition and compression test starting from the other end and number four cylinder.

You are supposed to do a compression test with all the spark plugs out !
for 2 reasons
1/ your battery doesnt get as run down (effecting the accuracy)
2/if the cylinders plugs are left in it changes the results (ie one 'dead' cylinder would impose less friction on the others being tested).

Also with the plugs in you need to open the throttle to get proper results.... (on 2 strokes the other cylinders are left in because the seals on the crank can effect the accuracy)

Thanks,

The spark plugs were only in by a couple of threads and to stop the excess petrol and oil mix coming out and making a mess.

As there was no carburation fitted it was the same as seeing a full throttle effect.

A friend put a spark plug partly screwed into the head as he span the engine on the starter motor, the sparkplug blew out and punctured his tank.
Very funny it was ! Stripped part of the thread as well. :D

John,

I re charged the battery that I use which is an over sized one and has plenty of reserve amps for such a test.
Starting at number 4 this time is got 1130 on the gauge, number 3 showed 1130 also, number 2 was at 1220 while number 1 reached 1200. I guess for an original engine that was fitted with new piston rings twenty five years back the results are acceptable?

Note, the gauge went down a little on the number 1 cylinder and before I took the picture.

It should be noted that this engine runs quite well, uses no oil worth the worry and does not smoke from the exhaust pipe.

While we have a Covit 19 lock down I am using the Imp Californian for the shopping trips, they are not allowed to be extended drives but they are adding some miles to the re built engine, also so sand and salt from the wet roads today :(

This is the first time in nearly six years that the car has been out on really wet roads, I will sponge the muck of with clean water and some Teepol Orange detergent.

Dave, Agreed and you have so much more to contend with where you are with the roads department salting the roads each freeze up.

I used buckets of water after the sponge down to rinse the muck of the wheels and suspensions, we cannot use a hose pipe here as since 2015 we have been under drought restorctions.

Some TLC today, small job but the recliner handles will look better when re finished.

The seats and controls are the cars original ones, I do have a second set of recliner seats that came from a 1966 Singer Chamois Sport but as yet I have no car to fit them in.

Pull off the handles and fit some black wiring heat shrink sleeve over the rods and refit the handles that how they were done on the upmarket Rootes cars, not painted.

Peter, well done that is exactly what I intend to do later today.
I had no idea that process was a Rootes one on some of their cars?

The Shrink Tube does the job fine on the straights, the corner is a problem, I need a thin soft wall black rubber tube?

Nearly there and while the shrink tube will be able to handle the bumps and knocks of the seat belt buckle a rubber tube will do the same and also take the bend without it
bunching up.

The sample shown would work even though its diameter is a little large, I do not have enough to do both handles, so that is a job to be done later.

By way of a comparison and placed on a South African map, the re built 1966 Singer Sport engine has now covered 1040 kms or 650 road miles.
used on a regular basis recently as our shopping car the engine runs really well.

With over a thousand kilometers driven I am pleased to note that the original filling of Shell Oils HX3 is staying clean, I am using a GUD Filters spin on filter code Z85, which is the replacement for the GUD filter that fits the early minis, the filters microns are also suitable for the Imps engine and thicker oils, the one I am using suits the later Chrysler Neon 1.8 ltr and Grand Voyager 3.8 ltr, also the Voyager 2.0 ltr.

A call to the GUD advice line advised a move to the later cars as the Mini filters may one day be discontinued?

The drivers side door glass has always been tight to wind up and down, It could that I have fitted a straight lower track and that the curved one I have in stock came from the Californian?

Yesterday I was sorting through my spare radiators and found one that will be the same as the one on the car now, excepting the early Mk1 forward facing nipple has been closed off on the spare one.

I should do the same on the one I am using now one day?

No overheating with the early Imp radiator by the way.

As I was never really happy with the hose and rubber bung fix I will solder a blanking plate over the tanks hole when I next remove the radiator.

I have just done a hot solder repair fix on a British Seagull petrol tank end that I had to remove to reshape it, so the solder and acid is in stock.

With an idea to a virus lock down project for the day, I chose the best of three radiators that I have and gave it a good cleaning with a wire brush and 60 grit floor sander paper.
I then sprayed it with DTM black paints for metal.

The radiator with the brass closure disc over the lower front forward facing hole was the best one, in fact it looked so good that it may be an OEM version and the upgrade from Mk1 to Mk2 Imps when Silverton Radiators used to produce for Stanley Motors here in the RSA?

As painted, I was careful to make sure that the paint reached inside the cooling vanes and from both side to help stop degrade from air and any stray fluids?

The radiator will now be plastic wrapped and put into storage for when I may require it at some time in the future?

South Africa, the well known radiator company Sliverton has branches in most centers for services, I have a complete radiator set here that carries their label.
In my case I use Radiator King as they are known for quick and reliable service, they also do a Door to Door service as well.

It is normal for them to phone me and advise when they last serviced the radiator as their sticker carries a tracking number.

Oli,

Yes, I actually started on it and then saw that the best way is to apply heat and remove the header tank, then I saw that I had a better radiator that required little more than a clean and a repaint, so that is now the spare and with a second one already reassembled with the cowl and wire mesh fitted, it was re done at some stage and never used?

We in South Africa are now into week nine of a forced lock down due to the virus issue, we were told three weeks to start with!

It seems that some small group in government is calling the shots and not the President? the issues on control are many, level four which is now, allows three hours from 6am to 9am for exercise only ( two hours of which are in darkness ) we cannot buy beer or wine, nor tobacco products and in the case of driving we cannot go further than five kilometers from our place of residence.

Since the rules were applied I have only used the Imp to do our shopping, I take the long way round to the shops to allow the engine to warm up properly.

So two months driving the Imp while the normal daily drives are parked for the duration.

Note, the lock down here has worked, as todays report is that some 18,003 have been found to have the virus and that 339 people have died from it, on the short side is that just over 500,000 ( only) have been tested this far.

Driving in the rain to the local Spar was not expected, we are now told to expect some snow as well?

The wipers were making a noise, both wiper wiper blades and the screen are as new, I have now added a few drops of clear Teepol to the screen wash water to see if that stops the noise?

Rain found its way into the parcel shelf under the windscreen, a reminder that neither the front or rear screen has been sealed yet.

Stop the wipers when they're vertical up the screen, remove the blades and rest the arm on the screen, is it flat on it, if not twist the end with some mole grips so it lies flat then refit the blades and try it, the wipers usually judder and make a noise one way if the blade isn't square to the screen.?

Well I have checked the angle where the wiper arm meets the glass when the wiper blades are removed, I see about a ten degree angle and have changed it to be close to level with the glass.

A wet road test will now be required, this is before I use the screen washer water with the Teepol in it as that would probably effect the results?

The rain we had this morning was a tad too heavy and for the first time in about five years the garage has been flooded from the back garden and into the garage, then under the Imp and to the front door, so the carpets are well soaked.

I will need a periscope to drive in that weather if it happens again?

A question, why would the arm angle make any difference when the wiper blade is hinged ?

Not that angle Roy! the angle across the arm flat, (cross section) to the screen so the blade sits at right angle to the screen in cross section then as the blade wipes the screens its not digging into the screen as it wipes one way and skipping over it.

Oh dear, I will see how they work next time I use the wipers, as re bending stainless steel can lead to a breakage.

My Trico wiper blades were new when fitted to the car a few years back, Bob of the Imp Club Spares Department supplied them.

As we can see, they sit way out of what I am told they should be, as in at 90 degrees to the glass, so I need to twist the wiper arms.

bit of heat whilst you twist them. You'll probably be best by removing the wipers first, and focussing the twist needed in the correct place. I bent stainless wiper arms before, on a Fiat 850 spider, all went well (also could it be the arm to wiper blade connections are overly loose, samewith the rubber to the mounting arm ?)

gratuitous picture included......

That's why they're noisy in operation it's like scraping the water off one way rather than wiping it off by the looks of it.

In December 2019 I fitted one of the spare water pump assemblies I keep in stock.

Just like the spare one that I had fitted the impeller seal faces with 316 flat washers to which were bonded with Loctite, that one was in itself a test unit.

That trial worked as the pump went into Eric Wells imp about November 2019, without any issues yet?

The test being to re use a pair of carbon seals, the original rubber backed ones, not those with stainless steel backings that we get here.

The seals here are now super expensive,R540 in our currency so 27.00 pounds in the UK (each) so to reuse what looked good to me was worth the try, did it work? yes and no is the answer.

I had a water leak to start, just the odd drip and even a twenty mile drive would do little to the water level in the radiator header tank, the leak stopped eventually. then recently the leak returned became larger than before, I have since replaced the pump with another spare assembly.

Today I have opened the faulty pump to find out why it had the leak? the bearing faces look good, in fact better than when I fitted them, it was a worn bearing on the pully side that was the problem, yes both bearings were fitted new last December and I always run with a loose fan belt, 1 " free play etc.

The seals and the impeller will live to run another day, I have spare 6202 bearings in stock.

The Caltex Extended Life Coolant has kept the parts nice and clean in use.
