You are just not driving it hard enough <GRIN>

Obviously, they will open slower (and possibly not as far) in colder ambient 
temps.  First the left one and then the right one.  They will close in 
reverse order.  Start the car five minutes before you are going to drive it 
if you are concerned about dropping a seat.  If it is that cold, you are 
going to want the heater going anyway.  Ping (detonation) leads to dropped 
seats.  It is almost impossible to hear it in a Rampside - much easier in a 
car.  If an engine is "too cool" the telltale sign will be a white 
substance, commonly referred to as mayonnaise, at the top of the oil filler 
neck.  I doubt you will find that condition unless you are running with the 
lower shrouds off in the winter.  Not a real likely scenario.

Later, JR
