Thread: Blue smoke....

Just driving down a hill in the landcruiser 80 series in low range, second gear. Heaps of blue smoke out the back, changed up to drive and it was better but still there. Got home and had a quick look, plenty of oil but a few bubbles in it, plenty of water in radiator, and transmission fluid. Seemed like choke ws on but nope checked that and it's working. Had a new head and top end replaced last year so not to worried about the bubbles in oil.

Anyone got ideas as to why a diesel will start putting out blue smoke all of a sudden?
