Welcome to the list Brian, I am sure you will have a lot of BTDT Spit
experience to share in the future.
I'll defer your question to some engine guy though.
All the best,
Bill

Subject: [TR] Valve Seals
Hello everyone,
This is my first posting to this list. Just a little introduction of myself:
My name is Brian Harlan, live in Munfordville (south-central Kentucky), I
bought a 68 Spit Mk 3 last fall to restore, I have also acquired a 70 Spit
Mk3 parts car. Currently, I am rebuilding the engine of the 68 (FE series).
Here's my question:
What's the deal with seals on the valve stems? The head off of the 68 had no
seals. The head off of the 70 doesn't either. Neither my Haynes, nor my
Bentley shop manuals mention them, but VB lists them with their valve train
rebuild listings. I ordered a set along with the valves, valve guides,
springs, etc., but now that I am at the point of re-assembling the head, I
am questioning the need for them. They are basically rubber O-rings, but
there is no groove on the valve stem to hold them. Anybody have a suggestion
to use them or not. Were they original on the FE series engines? Were they a
later addition? Anybody have experience with this type, if so, what do you
recommend?
Thanks for any help provided,
Brian
