[Staowners] SCUTTLE SHAKE REVISITED

[terry poole]

Hi All,

As I said many moons ago the only shake I've (my car, that is!)  
experienced was due to an out of balance prop. shaft and easily fixed  
with a new u/j.

I have seen so-called scuttle shake mentioned in relation to road  
speed but never to related engine rpm (different gears) which should  
be relevant especially to some of the fancy high-tech engine faults  
being debated?

If it is only speed related is it more likely to be caused by severe  
wheel wobble and nothing to do with the poor old much maligned engine.

If it were an inherent design fault somewhere, we would all suffer.

Long ago I also ran a saloon (sedan) with a broken head to scuttle  
rubber for a while and never noticed the difference until I spotted it  
visually.

PIp-pip,

Terry.  UK
