Diesels have very little piston/head clearance. If your cambelt breaks you
will at least bend all valves, split the valveseals/guides and probably
damage the cam, pistons, rods, big-end shells and possibly crakk... those
pistons & valves will hit HARD.


We have had the bad fortune to have belts break on 2 Toyota diesels; each
time the camshaft broke in 2 places.
