  • Valve guide seals
  • Another question on my engine rebuild...50 8n.
    Kit came with what I assume are valve guide seals, cant see what else they would be. There were no seals on the guides when I tore the engine down. Did all years use seals or would it just be a standard kit that I got and the 50’s didnt require them? Readin thru the “how to’s) it looks like the majority suggest using them on intake only (there were eight supplied with the kit tho).
    My parts book as well as most of the manuals I have been reading thru make no mention of guide seals.

  • They are listed in a parts book available on this site. Ford started using them on the intakes when they changed to the one piece guide. Even the flat head V8 only used them on the intake.

  • My parts book is just a newer version of the one you linked, (1939 thru 1953).
    I had another look and found it. The parts book I have doesnt show them on the picture of the valve breakdown but I found that they are shown on the “engine assembly inside” picture. And yes, I see they are “intake valve guide bushing seals”, 4 required!
    Having not had any on the guide bushings I removed and that they are not shown on the valve breakdown picture had me questioning it.
    Thanks again all, appreciate everyones replies....sure helps a newbie out.

  • some say only on intakes but where did they get that. I just don't believe the assembly line where guides were installed from pallets made assemblers pick sealed or non sealed guides for the engine. You have 8 why would you not use them, can't hurt a thing.

  • It comes from the parts book that calls for 4 seals-intake valve guides.
