RE: Return of the Rattling Spider Thread

["Robert E. Johnston" <coumnavy@domain.elided>]

In the 26 years I've owned my '73 Spider, I've had the "thin sheetmetal 
rattle" @ approx. 3K RPM that is being described a few times.  In all cases 
it was because the sump guard had been pushed up against the oil 
sump.  Either replacing the guard or bending back out to it's original 
shape has always fixed the problem.  The 2L engine seems to have a natural 
vibration band from 3,000 to 3,500 RPM.  Something else might be rattling, 
but check the sump guard (if you have one).
