Don't know if I am on the correct forum but need help identifying part of my 1958 TR3 engine. The engine is presently being assembled but I found one part i don't recogonize. Its a cap with the number 710 on top. Does anyone know what this is and where it goes? [image]https://www.timyoho.com/TriumphPage/TRstuff/Restoration/710cap.htm[/image]
