Some TLC for my QV

Not a 100% but I am pretty sure they were - I had no solvent that would remove the original paint so I sanded things flat before repainting. I am sure it'll last for a while though.

 

It's been around since the 50s.

 

Another small touch-up project - airbox cover had suffered some fuel spillage a while ago:

Luckily the printing wasn't affected, but I did touch up the missing white paint on the ufi

Those paints and brushes are really nice

Paint - I can't get any crackle finish here Image Unavailable, Please Login
Cleaned up, the paint line will eventually blend in better when it's all dried up and washed a few times

Re the clutch cylinder repeatedly failing: Heat might be the issue looking at the melted boot. I designed a heat shield based on the workshop manual's drawings and some photos I took:

And fabricated it from an old sheet of alloy to test fit: Image Unavailable, Please Login
It fitted alright

That's in the car at the moment. I then made a proper one with a head protection insert

Done, will be fitted the next time the car's up in the air:

Side observation - in Switzerland you can still get 100 Octane gas, which doesn't contain Ethanol apparently

As the spare tire belt is breaking down again, I had one made with a "safety belt" type insert:

And the jack bag got hard and cracked to the point where it wouldn't hold anything so I had one made; everything beautifully finished in good materials:

Modification to a 32 nut for speedo sensor fitting:

So - speedo keeps dropping to zero intermittently above 40mph so I pulled it to check the move the pot and add a tiny drop of WD40. No change, so crawled under car and saw this on the sensor plug:

Off it came and I drilled a hole through the red side of the plug so solder in a new wire. On the green side I was able to reuse the cores so added a new wire:

Prepped for refitting:

Refitted

... and the problem is still present, with a very recent speedo sensor?
So I refitted my original repaired sensor (see above):

... and the speedo works normally! The new sensor already failed... not good.

 

RHD only issue with the driver's footwell carpet due to the stepped floor (gas pedal torsion bar) - the carpet wears off really quickly due to the clutch pedal heel. So I had the carpet shortened to before the step:

Ally part made and trimmed with a 2mm rubber mat, fitted with velcro so it can be removed to access the panel screws.

Fitted, solid and cleans up the area permanently

Also, the cassette compartment screws were always loosening themselves so I drilled bigger holes for larger diameter screws:

I also fitted the final clutch slave heat shield

I noticed a proximity between the starter motor heat shield and the engine mount. I will have to get some clearance there:

Also the alternator air hose has not been fitted correctly so I got it back into its clamp:

Engine started missing again, as soon as she warmed up. Fuel filter checks revealed nothing:

Caps and rotors are perfect, all HT leads have continuity to extenders

But some, not all, extenders have burn marks:

They check out in terms of resistance though. I changed them:
Image Unavailable, Please Login
No change... The sensors all test out OK in terms of their internal resistance, both at the diagnostics plug and all the way down to the ECUs' plugs. I also tested all the wires up to the coils without finding any discontinuity. The coils' internal resistances are as follows (for reference):

Coil 1-4 low voltage 0.6 Ohm
high voltage 4.68 kOhm

Coil 5.8 low voltage 0.7 Ohm
high voltage 4.72 kOhm

Nothing obviously wrong other than a failed ECU? Before considering that I pulled the 3 sensors and they were very contaminated with clutch dust:

Could this be the reason for their failure at higher temps?

 

Nothing visibly or measurably wrong with old vs new sensor. But they need modifications to the holes spacing as you can see in the below pic:

very magnetic...!

3 new sensors that actually fit

and refitted - all three plugs at the car's side are broken by age. I secured them with cable ties until I can source a new loom or make one with new plugs:

Re the burn marks on the extenders both sides: I also noticed that the HT lead caps on the cam covers would not all sit at the same height and some of them wanted to be lower down = they'd pop up a few mm after fitting. Possibly the reason for the bad connections between the connectors and the plugs?

 

I decided to cut off the offending lip and sure enough, some of them are sitting inside the edge, nice and tight:

I cut them all off:

It's quite concerning to see the huge production tolerances on those HT lead ends. This is with all the ends sitting tight on the extender and on the plug:

And yes, the plugs are correctly fitted. And the engine runs beautifully again.

 

Would you sell them?

 

Very nice Guido!
