Does a Subaru Forester Engine Burning Oil Require Cylinder Block Replacement?

[TaylorLynn]

If a Subaru Forester engine is burning oil, it is not necessarily an issue with the cylinder block, and cylinder block replacement may not be required. Impact of Cylinder Block Replacement: Replacing the engine cylinder block, if accompanied by corresponding repair records, can affect the vehicle's residual value. Engine repair is highly technical, including cylinder head installation, which must strictly follow the repair manual. Improper installation may shorten the lifespan of new components or even cause other issues. Factors Contributing to Oil Burning: Worn or aged valves can compromise their sealing ability, making oil burning more likely; Excessive piston clearance allows oil to enter the combustion chamber, resulting in oil burning.
