The Cellette is key to straightening these. I am just amazed how long this sat under water and had no rust. The purity of the water, its constant motion and temperature I am sure played a huge role in that. If this were in a stagnant pool it wouldn't be here anymore.

Summer yellow is a unique color. Although it was not offered on the 993. Is it possible it is pastel yellow.https://www.rennbow.org/colorwiki/PastelYellow

This is a PTS summer yellow 964 RS. It is possible they are very similar if not identical paint codes. Porsche played names with colors such as Guards or India red which is a different name but same formula.

 

It is a PTS ordered vehicle, I am sure about this, not only because of the VIN, but also because I know what was behind such a choice. The vehicle had a very special story from the very beginning.
So far I've been able to find only another 993 delivered from new in Summer Yellow.
Pastel yellow is similar, less brilliant I'd rather say.

I am not very much inside corrosion principles, but magnesium stuff was melted away, aluminum gummy isolated parts (like suspension arms) had pitting, so I think it was the magnesium and the mud to save the vehicle

 

mag won't survive in water for any period of time. You are thinking it was acting like an anode? It is possible although I would suspect if the water was stagnant and warmer there would be even less mag left than there was.

Cool on the PTS.

 

All the weldings will be done with the body placed on the Cellette.
This morning I visit the rectifying shop, new exhaust valve in place, stronger than original ones, intake valve are perfect and will not be changed.


Some more scale must be removed from the spaces between the cooling wings

The ultrasonic bath isn't having effect on the engine and gearbox surface, so as second option we'll try the so called ice blasting. We leave as last option glass microspheres blasting, which I don't like to go for because it changes the surface finish.

 

Here is an episode on automobile corrosion
This guy is brilliant when it comes to explaining some basics.. The episode on the starter was very enlightening, I thought I knew how a starter worked until I watched this..

 

Nice video, very clear exposure.
Probably the barrier has been provided by silt, mud and very lower permeable type of ground like clay is.
The mud I personally took out from the car was more than 1500kg, and while sitting on the bottom of the river the car was totally underwater but also half submerged (approximately till the belt line) from mud.
it is a huge layer of mud (more than half a meter)to be overcome by oxygen, behaving like solid layer due to consolidation and with very low permehability coefficient.

however the magnesium has dissolved heavily and some aluminum parts that were in electrical contact with the magnesium had pitting.
The steel parts instead remained perfect, because there was a lot of aluminum almost everywhere to sacrifice itself for them, slowly, of course, but in those conditions for four and a half years.

Difference between pastel yellow (upper) and lemon yellow (lower)

 

Nice picture with the colors, and from them:

Pastel Yellow looks lighter than Summer Yellow, and

Lemon Yellow has less red in it versus Speed Yellow.

 

There is a story behind the color as well...and also behind the reason why the first owner ordered it in that exact color.

If someone can help me in a technical issue:

the chain sprockets that go onto the intermediate shaft must be just pressed or heated and slightly pressed?


Sprockets are brand new genuine Porsche, same as coupled gears 0-0 (from Sweden, thank you Patrick) and shaft is its original one.

This story would make for an excellent coffee table book one day.

Especially the search for parts was epic...now "only" the gearbox is missing.

 

After acid treatment and cleaning, less than 24 hours after the waterblasting the bare metal chassis was painted with a very thin layer of anti-rust, and she is already back on the Cellette to complete the chassis rebuild


Now she looks like a biscuit

Furthermore, this morning Fed-ex ringed the bell saying hello, is there Paolo at home... Yes, it's me.
OK, then this is your parcel...


Now the question is, boot or no boots?

Very good looking piece of aluminum, thank you Eurowise

The rear lower arm (shaped like a triangle) will be on harder rubber, since this is the part that has to face the longitudinal impacts coming from the roughness of the road.

Let's see how this mixed set-up will work.

 

Amazing progress, you have a huge set of stones taking this on. I can't find the "I bow" emoji but I do.

 

thank you Grapeape,
this project is requiring a massive psychological commitment to keep everything together, following many aspects in parallel at the same time, in a sector that, while adoring these cars, is not mine.
The most beautiful part of it in fact is: this is not my job and definitely not a job for me. (But it represents a huge amount of work)
If it was, I don't think it would have the same taste.
I do not think the final result will have anything less than a top end work of a professional shop, having leaned on professionalisms with excellent competence.

If anything, I hope the final result will speak clearly about the effort and the passion lavished not only by me, but by the subjects who by accepting the work, have been sucked in by the vortex of the limoncella

 

I got a psychological lift from seeing the bare metal all the way here in New York, so thanks.
