Genuine Nissan Front Crankshaft Oil Seal – RB20 RB25 RB26 VG30 – 13510-10Y12
Prevent unwanted engine oil leaks and maintain factory sealing performance with a Genuine Nissan OEM Front Crankshaft Oil Seal – 13510-10Y12, designed for a wide range of compatible Nissan RB and VG-series engines, including the legendary RB26DETT.
Located at the front of the engine where the crankshaft passes through the front oil seal housing, this genuine Nissan seal helps prevent engine oil from escaping around the rotating crankshaft.
Over time, original crankshaft oil seals can become hardened, brittle or worn due to engine heat, age and continuous operation. A deteriorated front crankshaft seal may allow engine oil to leak into the timing belt area or onto surrounding engine components.
On timing belt-driven engines, oil contamination can accelerate belt deterioration and potentially compromise the reliability of the timing belt system. Replacing a worn or leaking front crankshaft seal is therefore an important part of maintaining your Nissan engine.
As the front crankshaft seal is accessible during many timing belt replacement procedures, fitting a new genuine Nissan seal during a major front engine service is a sensible preventative maintenance measure.
Whether you're servicing an RB25DET Skyline, rebuilding an RB26DETT GT-R engine or refreshing a VG30-powered Nissan, genuine Nissan sealing components provide the factory-style fitment and quality expected from original equipment parts.

Why Replace Your Front Crankshaft Oil Seal?
The front crankshaft oil seal is an essential engine component that helps prevent oil from escaping around the crankshaft as it rotates.
After years of engine operation and exposure to heat, the original rubber sealing lip may lose flexibility or develop wear, increasing the likelihood of oil leakage.
Common signs of a worn front crankshaft oil seal may include:
- Engine oil leaking from behind the crankshaft pulley
- Oil residue around the lower timing cover
- Oil contamination inside the timing belt area
- Visible wear, hardening or damage to the original seal
- Oil accumulating around the front of the engine
Oil leaks in this area may also originate from other engine components, so the source should be confirmed before replacing the seal.
Recommended During Timing Belt Replacement
Replacing the front crankshaft oil seal while the timing belt and crankshaft pulley are already removed can help avoid the additional labour involved in accessing the seal at a later date.
This makes the genuine Nissan front crankshaft oil seal an excellent addition to:
- Timing belt replacement services
- Timing belt and water pump upgrades
- Front engine oil leak repairs
- RB20, RB25 and RB26 engine rebuilds
- VG-series engine maintenance
- Preventative maintenance on ageing Nissan engines
Important: If engine oil has contaminated the timing belt, inspect the complete timing belt system and replace affected components as required before operating the engine.
Important Installation Information
Correct installation is essential to ensure effective sealing and prevent premature oil leakage.
Before installing the new seal, inspect the crankshaft sealing surface and surrounding housing for wear, damage or contamination.
Use suitable installation tools and follow the applicable Nissan factory workshop procedures for seal orientation, lubrication and installation depth.
Avoid damaging the sealing lip or installing the seal unevenly, as incorrect installation may result in oil leakage.
Professional installation is recommended.
