  • If you don't know what type of exhaust valves you have, do not start your engine!

Detecting with Heads off

Inscriptions on Stem of Sodium-filled Valves
The original valves may break

There is an inscription on the stem of the valve.

  • If the following inscriptions are present:
  • ELBMFS -- Eaton Livia Bi Metal Filled Sodium
  • ELBMSTFS -- Eaton Livia Bi Metal Stellite Filled Sodium

You have sodium in your valves. -- Replace ASAP.


Detecting with Heads on

  • If you don't remove the heads but remove the tappets and shims you can put a magnet on the valve stem.
    • If the valve stems are completely nonmagnetic they are stainless.
      • Therefore are not the OE sodium filled valves which were made of a magnetic alloy.
    • If they are magnetic they might be sodium filled or they might be solid, but of a magnetic alloy.
      • Some of Andrew's early solid valves are slightly magnetic.
      • His later ones were completely non-magnetic.
      • You may be "reading" some magnetism from the keepers, which are iron.
    • The sodium valves are really magnetic.
