[quote="Dinofanwim"]Hey Dinoswede,

You are absolutely right about the engine number. Sorry! (I think it should be 0001540)

However my postings as regard to the finish, are 100% right!
Now, it might be possible that during production of the 2.0 l engines, there have been 2 different types of paint treatment.
Or perhaps, as Patrizio and I are suggesting, that it was an update to be carried out by the Fiat dealers!

In any case, a very good protection to any kind of magnesium item, is to first get ridd off all oxydised material (= the white powder) and give it a first treatment with an epoxy primer. This will seal your precious covers well.
And as for the finish, I suggest to either use the black heat resistant wrinkle paint or if you prefer, a semi gloss dark grey paint. (It should be noted that in general the wrinkle paint is prefered, like on an old V12 Colombo Ferrari engine!) ( VHT plus is a good product at affordable prices!)

Now, if you are looking to modify your Dino to your own ideas, you can also finish them in another colour, but once again, I would go for a heat resistant wrinkle paint. (On black the dirt doesn´t show up so quickly!)
Just to show to all of you, it is with reason that many car manufacturers have been using, and some still use this heat resistant paint!
Furthermore, if it was indeed an up-date to be carried out by the dealers, Fiat has informed their dealers not for the fun!
Of course, everybody is free to do what they want, but IMHO if you paint them like I suggest, it cannot be considered as a fault!
As far as the 2.4 l engine is concerned, please note that mine also has the satin gloss dark grey finish!

New member as of today.
My father owned a Dino 2.0 Snyder from new and between my friends and myself have owned 10 various models in the past.
The valve covers were never ever crinkle finish. Always bare magnesium or whatever alloy!

Hey Fred,

I have no doubt about what you write about the wrinkle or crackle paint.

But my Dad had a 2000 Coupé with that paint on the covers!
Also the car I bought earlier on this year, which was produced around the same period, still has remainders of that paint.( Have a look at my postings.)
Furthermore i came across a German who has a 206, and yes, the cover was also covered with this wrinkle or crackle paint.

As I have been involved in motor racing, especially with Mini's end of the sixties in the UK, I know that magnesium wheels have a date stamped in it. ( Just have a look at the original Minilites!) Due to oxydation,magnesium parts loose their initinal strength. So cars fitted with wheels that had passed the expiry date, failed in scrutineering!

The original Minilite wheel, was probably the most successful competition wheel of the 1960’s and 70’s. As the name suggests, it was originally developed as a magnesium competition wheel for the then revolutionary new Austin ‘Mini’, but its instant success meant that it was soon to be seen on many of the serious race and rally cars of that era. A new iconic style was born, and to this day, all genuine Minilite wheels are made to that original classic design. Manufactured exclusively in the UK, Minilite wheels are ‘Low-Pressure’ die cast, in high grade aluminium alloy; machined on the latest CNC equipment, 100% pressure tested, and finally powder coated for maximum protection against the elements. ( but its oxydation can't be compared to magnesium!)

To see what happens with magnesium, please visit this site! http://www.theroaringseason.com/showthr ... Car-Wheels

We all know that the 2400 engines are equipped with aluminium covers, whereas the 2000 Dino my Father owned, had magnesium covers, like so many 2.0 l engines.

Of course, everone may do as they please, and so do I!

Wim, in Italy a old proverb says: one swallow does not make springtime :D

As for the engine Dino 2400, the head cams covers were made in aluminum because it was useless save hundred grams making them in magnesium, when engine was made in cast iron ;)

I don't think was a problem of corrosion ...

How many Dino engine have you seen with magnesium cams covers perforated for corrosion?

I never seen one !

As far back as the late 70's and early 80's there were Dino specialists such as Joe Nash racing and various others, that when they carried out an engine rebuild, and believe me most of them were already knackered by then, I for one used a Dino 2400 coupe and Spyder as daily drivers, hammering them into the ground, they would often jazz them up with wrinkle finish cam covers and Dino badges all over!

Fred,
even here in Italy has happened and still happens (unfortunately) the same thing.
This "social phenomenon" has a name: it is called tuning ...

Just one decides what he wants to do with his car, in relation to what he likes, and declare unequivocally, so the Dino's fans, twenty years later, should not go crazy on the forum :lol: :lol: :lol:

Only the 2000 engines had the magnesium covers, and as I calready explaned, the crackle paint came off in big flakes.
This could aleady start within 2 years after delivery!
Therefore it is rare to find these remainders on a old car.

In any case, my list of people who agree with me is growing!
1) there was my Dad´s car.(1971 when I noticed it!)\
2) my own Dino which has been in California (Dry climate)
3) A guy from Germany who wrote that one of the cam covers of his 206 (the magnesium cover) had it. The other cover was in aluminium
4) Mark Devaney has come across several 206 engines with remainders of the crackle paint.

So it is well worth to look a bit further into the matter!

And I suppose that the pictures off my own 2000 are enough proof!
