2023-2024 Toyota Camry, Crown, RAV4 Engine Oil Leak TSB

Toyota has released Technical Service Bulletin (TSB) T-TT-0765-24 to address an Engine Oil Leak From The Cylinder Head Cover in certain 2023-2024 Toyota Camry, Crown, and RAV4 models. This TSB provides guidance to technicians on how to handle vehicles exhibiting this specific oil leak condition.

The issue specifically concerns an oil leak from the cylinder head cover, near the union of the timing chain cover and cam housing. Owners who notice signs of an oil leak should have their vehicle inspected promptly by a qualified Toyota service center.

Symptoms

Owners of affected 2023-2024 Toyota Camry, Crown, and RAV4 vehicles may observe an oil leak from the cylinder head cover. This might manifest as visible oil stains on the engine, a burning oil smell if oil drips onto hot exhaust components, or a noticeable drop in engine oil level between service intervals. If you suspect a Toyota Camry oil leak or a leak in other affected models, it's crucial to address it to prevent potential engine damage or other issues.

Diagnosis / Trigger Conditions

The condition is identified when a technician visually confirms an oil leak from the cylinder head cover, near the union of the timing chain cover and cam housing. This typically involves a thorough inspection of the engine compartment. The TSB specifies that this diagnostic procedure should be followed if an oil leak is suspected in the listed models.

Important Warnings

Toyota's TSB T-TT-0765-24 provides a critical instruction for technicians: if an Engine Oil Leak From The Cylinder Head Cover is identified and no mechanical engine repairs have been attempted, technicians must halt diagnostics and create a TAS case. A TAS (Technical Assistance System) case allows the dealership to consult directly with Toyota's engineering and technical support teams for complex issues. If the condition is identified on a weekend or holiday, the TSB advises to proceed with the repair and contact TAS on the next available business day. This procedure ensures that the issue is properly documented and that the correct repair strategy is applied, potentially avoiding unnecessary or incorrect repairs.

Owner Action

If you own a 2023-2024 Toyota Camry, Crown, or RAV4 and notice any signs of an engine oil leak, especially around the cylinder head area, you should schedule an appointment with your authorized Toyota dealership. Inform them that you suspect a Toyota Camry oil leak or a similar issue in your model. Mentioning Toyota Tech Tip T-TT-0765-24 (T-TT-0765-24) can help ensure the service department follows the prescribed diagnostic and repair protocol, including the creation of a TAS case if applicable. This will help ensure the issue is resolved correctly and efficiently.
