What's the story on the various Triumph engines, in case of timing
drive failure ? I guess we know now that there's a valve crash on
the TR-6 and presumably the other 6-cyl engines, as well, but then,
Maybe not !
Various belt-drive OHC engines are known `crashers', such as the early
Ford Escort 1600s, AMC/Renault 1700s, Isuzu 2600s, etc.
What's the history of the Triumph OHV chain-drives ?
Inquiring minds wanna know.
