5.Set compression gauge to
one of the spark plug holes. 6.Crank the engine with the throttle valve fully open and measure the compression pressure. Standard value (at engine speed of 200 r/min):
Limit: Maximum 98 kPa 8.If there is a cylinder with compression or a compression difference that is outside the limit, pour a small amount of engine oil through the spark plug hole, and repeat the operations in steps from 5 to 7. (1) If the compression increases after oil is added, the cause of the malfunction is a worn or damaged piston ring and/or cylinder inner surface. (2) If the compression dose not rise after oil is added, the cause is a burnt or defective valve seat, or pressure is leaking from the gasket. 9.Connect the crank angle sensor connector. 10.Install the spark plugs and ignition coils. |
