Newbie Eric has raised a question as regards TR oil leakage.  I should just
like to point out that rather than being problematic (as was implied in his
question) this was another fine example of forward thinking on the part of
Standard Triumph (and the entire British motor industry i should think). The
slow seepage of petroleum products is a planned occurrence. Believe it or
not, the engineers of the time realized that these cars would remain popular
well beyond normal vehicle life spans, and therefore engineered in a rust
prevention mechanism to prevent chassis rail rust out. (Unfortunately,
chassis design changes starting with the TR4A created a disturbance in the
airflow, and thus the oil misting pattern under the vehicle which resulted
in the rearmost frame rails eventually suffering from tinwormitis.)

 History tells us that the original intent was to also provide upper level
"oil misters" to protect the inside surfaces of the fenders (wings) however
the Sales Department intervened and a compromise was reached in the
development of "screw-on" type wings. The theory being that a typical owner
though neither having access to nor a mastery of panel beating tools and
welding torch, would however possess the acumen required to use the supplied
screwdriver to replace any rusted panels.   It was a plan well devised as is
evidenced by the large number of British automobiles still oiling the
driveways of several nations.
