Blue smoke on start up

[bigbennymq]

On the start up of mi mq patrol (diesel) there is a shit load of bright blue smoke dont know why its blue could it be the oil not being burnt ??????????????

if its only on start up then most likely your valve stem seals are gone and need replacing, luckily you can do this without removing the cylinder head

Mine does it unbelievably bad, esp when it is cold.

My problem is al the vege oil i run in it and when she warms up its all good.

I wouldnt worry, not worth spending money on an old truck

is it blue or white if it is cold and the smoke is white it is dirty injecters which is unburnt fuel to check if it burns your eyes and stinks its the injecters
