Once again Ron Clements comes up with some interesting disaster pictures.
This happened on the way home from the November FSW Meeting.
The Piston took a fair pummelling considering Ron stopped immediately.
Luckily ? the Valve Stem stayed in the Guide as it was bent anyway.
The inquest has already started.
As has the rebuild, you do not see the Clements Boys off the road for long.
The Piston is scrap.
The likely reason is the valve guide broke up over a period of a few weeks as Ron had noticed a change in performance. As more of the guide got hotter and broke away then eventually the stem of the valve was unsupported and it bent / broke.That is unless you know better ?
