Which risk increases in a turbocharged engine when piston ring end-gap clearance exceeds manufacturer specifications?

💡 Explanation

When piston ring end-gap exceeds specification, increased blow-by occurs because the rings lose some sealing capability, allowing combustion gases. This increased volume of gases forces oil past the rings increasing oil consumption. Therefore excessive oil consumption arises, rather than other mechanical failures arising from totally different failure modes.
