Ray, This is the right way to run you compression test. However, your
results do not sound very good. Your pressure should be withing 10 percent
of each piston. Number 1 and 4 look good. Number 2 and 3 look bad. Have
you noticed a loss of power or rough idle. My guess is you have blown a
head gasket between the 2nd and 3rd cylinders.
Let me know what happens.
