Known Issues

Head Gaskets:

While less common on EJ253 compared to earlier EJ25s, head gasket issues can still occur. The EJ255/EJ257 are generally more robust. The EZ30D H6 is typically very reliable in this regard.

Oil Consumption:

Some EJ25 engines may exhibit increased oil consumption over time, especially when driven hard. Regular checks are advisable.

Cv Joints:

Front CV boots can wear and tear, leading to joint damage if not addressed promptly, particularly under harsh conditions.

Catalytic Converter:

Can become clogged over time, particularly if there have been engine misfires or oil burning issues.

Automatic Transmission Shifting:

Some owners report occasional rough shifting in the 4EAT or 5EAT transmissions. Fluid changes and potential valve body issues can be addressed with this manual.
