[s-cars] The "myth" of plugs blowing out of 20vt heads.

[K Hayes]

Loss of performance and a distinct sound alerted me that something  
was up a few months after I go the car.  This list pointed me to  
check the plugs.  Basically, tightened them past the 22lb/ft like  
Gerner explained and never had a problem again 4 years.  I had one  
very loose and two others that needed at least 270 degrees on the  
socket before they were seated.  3 outta 5 ain't bad.  I have checked  
them since maybe twice, and everything was as it should be with no  
tightening needed.
