mysterious piece

Has anyone ever seen another Flaminia engine with this venting over the valve covers?
I can not find any other image.
Brevetto D.G. Torino
Thank you

No,

Giovanni do you have access to the engine/car or did you only come across the pictures? It would be interesting to know where the tube coming out of the device goes to. Does the engine have that on both sides?

Hi Hubert,
this is the engine of my coupe 2500.
It's a 823.00.
the device is present on both sides. the conduit has a first part in aluminum, then ends in rubber.
they are cut one near to the oil filter, the other one is sliced under the brake servo.

what do you think the purpose was? Provided there is a small vacuum coming from the carb and probably some also very small pressure from the crankcase (blow by of the pistons and some airflow resulting from the turning crankshaft).

What is supposed to happen in the tube? Exhausting the fumes evaporating the crankcase? Why should it do that, while the carb sucks them in? Adding some fresh air to the crankcase fumes?Why?

in my opinion the idea was to remove the hot vapors to improve performance. I do not know if it works because the carburettor sucks ...
the strange thing is that nobody has ever seen this device on another engine.
it would have gone well on the engine of the racing hydroplane you had in the workshop, it did not have the filter box...

We can figure out its effect on the performance once my power testing station is in operation

These are not connected to the carb with hoses are they? Appear to be just weird crankcase vents.

The rubber pipes that connect the carb were not actually present when I retrieved it from the barn. was there from the late 60s.
The filter box was empty, the filter was missing.
  But the caps and the filter have the standard connections and I think that the rubber pipes were there, otherwise the top of the engine gets dirty with oil. he was not anointed ...

Another thing of which I am not sure are the mufflers.
They are different from the current imasaf.
Hubert, were they like that on your coupe?
(in the image I repainted them, only to have them while I was testing the engine)

Thank you

Giovanni

Flaminia engines tend to spray the whole engine bay with oil once they get old. Apparently venting via the carbs is not too effective. IMO Brevetto saw a market there and offered this solution.

The rear mufflers are not correct, IMASAF design follows the original.

Hubert

BTW: The pic of the dirty car is gorgeous!!!

I think that this is the most valid hypothesis.

"The rear mufflers are not correct, IMASAF design follows the original."

Thanks to the indication, I will arrange to install a new system when the time is right.

"The pic of the dirty car is gorgeous!!!"

Thanks, always elegant even dirty (and rusty)
Hubert, sometimes I saw a black coupe in your lab, how do you think black on these cars? do you think it is a crime to choose a color that is always original but different?
Thanks
Giovanni

Hi Giovanni,

the black Flaminia is still in the shop awaiting an engine rebuild.





There are some basic standpoints regarding the colours. We had some discussion on my resto blog a while ago. My personal opinion is, it is your car, it is your taste and your decision, do whatever you like. Black was available for the Coupé, wasn´t it? And even if not, it suits the car well, fits in the cars production period, nothing to say against it. What I would not do, is paint the rims black, as with my friends car.

My general attitude is, stand for your decisions. And when choosing pink for the Flaminia, ok, but prepare to have a couple of rough decades ahead of you

Globally you are not too far from here, perhaps 1200 km or 1400 km. Come over and inspect it in the flesh!!

Thanks for the advice, it's not an imminent decision.
I share your ideas.

Newer engine do suck crankcase oil vapors back into the intake, as with the 164 at least. That particular vapor recovery can doesn't work all that well, slowly getting gooped up with crud, the return drain line to the crankcase plugging, and the end result is oil and vapor leaking into the intake bellows and the AFM, even from there to the air filter box.
