1)  What is the standard procedure for removing valve  seats?







The most commonly used procedure involves driving up a long hill in  hot 
weather, then immediately coasting down the other side using engine  
compression to slow you down.  Then a seat comes loose.
 
That simulates the approved shop method of heating the head in the oven and 
 shooting cold air on the seat to shrink it loose.
