SOURCE: white smoke from exhaust

not sure what your question is regarding but white smoke coming out of the exhaust usually means water is getting into the cylinder. If this is the case then you never know when the motor is going to go so just do whatever you need to do as quicky and cool as possible

black smoke is fuel white smoke is oil. change your spark plugs to a hotter plug and run with some hpr 50 engine oil or somrthing nice and thick

i have a simialer problem but i was getting neat fuel out the exhaust as well . i removed the engine because id got a replacement then stripped the old one and as i thought it was a valve timing problem.looking at the engine from the front the cams on the left bank had jumped one tooth out of time so fuel was not being burnt and coming straight through the exhaust.strangely it didnt seem to have a big missfire and idling and smoke got worse when warm.

You likely have worn valve guides
