8. If there is a cylinder which compression or compression
difference is outside the limit, pour a small amount of
engine oil through the glow plug hole, and repeat the
operations in steps 6 - 7.
(1) If the compression increases after the oil is added,
the cause of the malfunction is a worn or damaged
piston ring and /or cylinder inner surface.
(2) If the compression does not rise after the oil is added,
the cause is a burnt or defective valve seat, or pressure
is leaking from the gasket.
9. Connect the fuel cut solenoid valve connector.
10. Install the glow plugs.
