Another issue from the Very Long List is the ticking noise from the engine. Since I bought the car in 2006 this noise has always been there. Setting valve clearances and a complete rebuild of the rocker gear didn’t fix the problem. www.narrywoolan.com.au/lancia-aprilia-1070/Rocker-gear
With all the other engine problems going on I’ve started a complete rebuild, more details to follow in the future! Extracting no.1 piston reveled the source of the ticking noise, a broken piston ring. How long it’s been there I’ve no idea but luckily there was no damage to either the bore or piston.
The engine was rebuilt in the UK back in 1991: (www.narrywoolan.com.au/lancia-aprilia-1070/uk-restoration-notes/note-5, and was fitted with AE/Nural pistons, quite different to the originals.
