Toyota Diesel 2L-TE OEM Front Crankshaft Seal 90311-42026

Product Overview

Genuine OEM Toyota Front Crankshaft Seal compatible with a wide range of Toyota vehicles equipped with 3S-GE, 3S-GTE, 3S-FE, 4S-FE, and 2L-TE engines. This precision-engineered crankshaft oil seal mounts in the timing gear or timing chain case to prevent engine oil from migrating past the crankshaft snout, a critical function during timing belt service, engine rebuilds, and swap projects. Genuine Toyota construction ensures correct interference fit, proper sealing lip geometry, and long-term durability across the full operating temperature range of these engines.

This seal is required for replacement whenever a timing belt or timing chain service is performed. Installing a new seal during timing belt replacement costs virtually nothing in additional labor but prevents an oil leak that would require removing the entire timing cover again to address.

Key Features & Benefits

• Stops oil leaks at the crankshaft snout: Engineered to the exact OEM interference fit and sealing lip profile for 3S-GE, 3S-GTE, 3S-FE, 4S-FE, and 2L-TE engines 
• Genuine Toyota construction: OEM rubber compound and PTFE lip sealing technology matched to Toyota factory specifications for heat resistance, flexibility, and crankshaft contact pressure
• Protects the timing belt from oil contamination: A leaking front crank seal saturates the timing belt with engine oil, dramatically accelerating belt degradation and creating a catastrophic failure risk in interference engines
• Essential timing belt service component: Replacing this seal adds only minutes to a timing belt job and eliminates the need to repeat the entire job if a leak develops, a standard practice recommended across Toyota enthusiast communities

Important: This seal is specific to the 3S-series and 2L-TE engine families. It is NOT the correct seal for 1JZ-GTE, 2JZ-GTE, or 5S-FE applications — those use different part numbers. Always verify your engine code (stamped on the engine block) before ordering. The Crown S150 LS151 application has been confirmed via Amayama OEM catalog model-level fitment data; verify against the Crown LS151 engine oil pump diagram (section 1501) on Amayama or Megazip before finalizing. The 3S-GE BEAMS engine in the Altezza SXE10 uses this seal at the front crankshaft position; confirm with your OEM catalog if your application falls outside the vehicles listed above.

Installation & Maintenance

Installation Difficulty: Intermediate
Tools Required: Seal driver or appropriate socket matching seal OD, crankshaft holding tool, torque wrench, timing cover gasket set
Professional Installation: Recommended unless performing as part of a full timing belt service, you are already comfortable completing

Maintenance Tips:

• Always replace this seal during every timing belt service interval. On 3S-GTE and 3S-GE engines, the timing belt is an interference design, and oil contamination from a leaking crank seal causes catastrophic belt failure
• Lightly lubricate the sealing lip with clean engine oil before installation to prevent dry-start lip damage and ensure proper seating
• Drive the seal in squarely using a seal driver sized to match the seal OD, cocking the seal during installation causes immediate leakage
• Inspect the crankshaft sealing surface for wear grooves before installation; a worn snout journal may require a repair sleeve (Speedi-Sleeve) for the new seal to seat correctly

 

Frequently Asked Questions

Q: What is included in the package?
A: This listing is for a single genuine OEM Toyota front crankshaft oil seal. A complete timing belt service on 3S-series engines also requires the rear camshaft seal (90311-46004 on BEAMS 3S-GE), timing belt, idler pulley, tensioner, and water pump — order all components together to complete the job in a single service interval.

Q: Will this seal work on the 2L-TE diesel in my Hilux Surf LN130?
A: The OEM catalog confirms 90311-42026 is used in the Hilux Surf LN130W with the 2L-TE turbo diesel engine, specifically in the engine oil pump circuit at the front crank position. Verify your specific production date against the OEM parts diagram before ordering, as diesel applications may use an alternate seal depending on the exact build date.

Common Symptoms of a Failed Front Crankshaft Seal

• Oil weeping or pooling on the front of the engine below the crankshaft pulley
• Engine oil visible on the inside of the timing cover or coating the timing belt
• Timing belt glazed, darkened, or showing accelerated wear — oil contamination drastically shortens belt life
• Oil mist or burning oil smell from the front engine bay — oil migrating from the crank seal onto hot exhaust components
• Oil seeping from the crankshaft pulley bolt area, particularly visible after a hot soak
