      From the owner’s manual:

      Check compression pressure

      Remove each glow plug and check cylinders, one by one, using a compression pressure gauge. If the pressure differs by more than 3.0 kg/cm2(42.7 psi) between cylinders or if the cylinder pressure is less than 30 kg/cm2 (427.0 psi) at 200 RPM, correct it.

      Was there a big difference between cylinders?
