I heard about blue smoke is caused by worn seals. Is it possible by too much oil?

If I remember correctly,blue smoke is from leaking valve stems if the thing smokes during the first few minutes of being cranked.While white smoke comes from higher temp,blown head gasket,cracked head or block.I heard about blue smoke is caused by worn seals. Is it possible by too much oil?
too much oil does cause blue smoke from the tail pipeI heard about blue smoke is caused by worn seals. Is it possible by too much oil?
Yes, blue smoke means your engine is burning oil. It must have high milage...it could be worn valve seals or piston rings. It could also be a blown head gasket.





EDIT: White smoke is caused by anti-freeze in the combustion chamber - blown head gasket.
Blue smoke means your engine is buring oil along with the gas it should be burning. It will ruin your engine if you don;t fix it.
yea, if you overfill the oil the engine will burn the excess but the blue smoke could be caused by other things as well
Yup. Could be cylinder head gasket.
