My '86 Renault 1.7L gas engine had sodium filled exhaust valves, as I found out when I
broke a timing belt... I never could figure this out, since the HP of this engine was pretty
pathetic... The valves were the most expensive part of the repair by a long shot - had to
come from France. This was the first (and possibly last) non VW/Audi I've owned...
