The purpose of the Sodium is to transfer heat from the valve head to the valve stem and then into the cylinder head. The Sodium melts into a liquid inside the head of the valve and due to the valve motion it splashes up into the stem, transferring heat into the cylinder head. Think of it as a liquid cooled valve. Sodium filled valve have been common on high performance aircraft since the 1920s but have largely been replaced by Inconel valves.

That's the cleanest non existing part of that lift🤔
-
You should have dumped some of it in water and watched the fun!

The young lady in the background “cleaning lift” was funny. I was thinking what the hell is she doing?HA HA

This is what happens when you hire shop helpers from the Paris School of Mimes.

mid 1970's Chevy / GMC trucks in heavy duty applications like camper specials, had sodium filled valves, my mechanic classes in mid 1980's had invoices from dealerships on them, and students were allowed to play with the valves, cut them open. I still think its cool to this day

It's used since Lindbergh's "Spirit of St.Louis", and blown car-engines still use such valves. It lowers valve head temperature by 100°C

Nice video. Like a history lesson for me. I did engine work back in the late '70's, and always had to be aware of these things in several muscle car engines of the time. the rule in that shop was "never re-grind a sodium valve - replace them". We weighed them to determine if they were sodium or not.

I have some sodium filled valves in my shed which were my fathers when he used to race - He stopped racing in 1957!!!!!!!

The cleaner. Thanks for that, Saab Aero's have sodium filled valves too and I never stopped to think past 'Salt ? really ?' The little darlings chuck over 250 horses at the tarmac, even after 20 years of strong service, and I have two of them. Can't afford those Italian cars you were talking about.

I ran sodium core valves in 1980. They were state of the art and very expensive back then.
-
Today I learned that Ferrari has sodium filled valves,and that lifts have invisible parts which need to be cleaned! 😂
-
Very cool. I've never cut one open before. Thanks for sharing.
-
I had actually wondered precisely what they looked like inside so thank you.

New segment: Science and Engineering moments with Chazz. 🤣 I love when u disassemble stuff for us to see how it’s made. Had no idea they used that solution in the past. That’s a great question for gear head trivia night.

my uncle Jim was a machinist and way back in the 50-60s he told me if they wanted to check if a sodium filled valve was ok to use they just tossed it into a pail of water ... if it was good no reaction but if it was cracked it would go bang.

Cool, always wondered what the sodium looked like! Subscribed.

Legend has it that Enzo would only season his food with this mystery paste.
-
So how do they actually make valves and get the sodium sealed inside?
-
Air polishing?
