I am about to replace the rocker bushes in my TF. Can someone advise me
which way around they go in?. I know that the oil hole in the new bush
should match up with the hole in the rocker arm, but the new bushes have an
oil groove which covers about 75% of the inner surface ,leaving about 25%
plain. Should this plain part be positioned in the area of greater thrust ie
at the bottom of the rocker?. Or maybe it does not matter as long as the oil
holes match. The old bushes were assembled wrongly and an oil hole drilled
following assembly so I do not have a pattern to work to. I have also been
told that some later rocker bushes do not have oil grooves at all, providing
greater wear area.
All advice gratefully received,
Regards
David Tinker
