The symptom of a leaky valve cover gasket is a VERY erratic idle 
(high one moment and then dying out the next).  I had it happen on a 
140FZ, and I saw it happen to a US Team Member at the 97 World 
Championships.  The solution as noted below is to surface the valve 
cover and to use a new gasket.
