#2 The glowplugs tips break off and destroy the motor.
Caused by condensation build up in the intake (in humid conditions) and on first startup the cold/hot shock shatters the glowplug tips.
Both well know issues with them and Toyota aware

The earlier KD engines have been fine. Only been an issue when injectors have failed or people used a crappy plug in ECU to get more power and the AFR where all screwed up.
