Mk1 rapid steel exhaust valve white seal

[Maxwell]

Can any one tell me where I can get the white seal that fits inside the mk1 steel exhaust valve.
Thanks Les

I believe all the existing supplies have been exhausted.
You can either replace it with a black Delrin valve-body...
Or you might be able to Make a new white seal....
The expert on this is KevG.. give him a ring!

Good Luck,

If the seal is still in the valve you could try dropping the whole valve in boiling water which softens the seal then tighten causing the seal to extrude a bit more.
