late and not so relevant...I seduced by catalog to installing this external line in my rebuild, suffered
high oil consumption, finally removed this as part of a general frustration, but not as a direct reasoned action...
oil consumption hugely reasonable now...other aspects improved... less misted oil now gets sucked into
intake through the valve cover to manifold hoses... this being carburetted 1974 US spec tr6. this oil feed
line is complete bogus for a street-spec, stock TR6.
