Assume you mean that it's burning oil. Typically that's because of poor maintenance or abuse.
- There are several reasons that an engine will burn oil and most of the time these are caused by inadequate oil changes:
- poor piston ring seal (cylinder taper, worn rings and/or carbon deposits in the piston ring grooves.)
- Worn or faulty valve guide stems
- SOMETIMES bad rod bearing can cause pistons to vibrate, allowing too much oil to remain on the cylinder walls.
- A cracked piston can also cause quite a bit of oil burning, but that's quite rare.
Also
White smoke indicates coolant entering the combustion chamber. Normally caused by a blown head gasket or cracked head. Blue smoke is oil burning, and black smoke is an overly rich fuel/air mixture.
IFit's black smoke (too much fuel) it can be caused by a sticking injector, faulty sensor or plugged air filter.Note that if coolant is entering the combustion chamber there will be other indicators, such as serious misfiring and/or coolant will be blown from the water jacket. Without those indicators you are probably not getting water in the combustion chamber
