Toyota Kluger: 2GR-FE/FKS Front Timing Cover Oil Leak at Gasket

The 3.5L 2GR-FE and 2GR-FKS V6 engines fitted across both the XU40 and XU50 Kluger are widely documented to develop oil leaks from the front timing chain cover gasket and associated cam seal areas. The leak path forms where the large aluminium timing cover meets the engine block and both cylinder head mating faces. Thermal expansion cycling over high mileage degrades the RTV sealant and gasket material, allowing pressurised oil to weep out. The repair requires stripping the front engine accessories, harmonic balancer, and timing cover to re-seal correctly. A neglected leak can contaminate and destroy the serpentine belt or ignite on exhaust components.

• Oil residue or wet staining on the front-lower engine block behind the crankshaft pulley area
• Oil burning smell from the engine bay during and after driving
• Serpentine drive belt contaminated with oil causing intermittent squealing
• Oil drips on the ground forming directly under the front of the engine after parking
• Visible oil seepage in the valley between cylinder banks near the front timing cover seam

1. 1

   With the engine warm, inspect the front of the engine block behind the crankshaft harmonic balancer with a torch for fresh oil weeping along the timing cover seam.

2. 2

   Check the serpentine belt and tensioner pulley surfaces for oil contamination.

3. 3

   Verify whether the engine has any prior oil leak repair invoices.

4. 4

   Look along both cylinder head-to-timing-cover joint lines for dried oil residue.

Parts involved: Cylinder head, Timing chain.

$1,500 to $3,800 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

• “Has the vehicle had any oil leak from the front of the engine investigated?”
• “Has the timing cover gasket or front crankshaft seal been replaced at any point?”
• “Is the serpentine belt free from oil contamination and when was it last replaced?”

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.
