Front crankshaft oil seal for Nissan engines
Keep engine oil where it belongs. This precision lip seal sits in the timing cover and hugs the crank nose to stop leaks at the front of the motor. Built from heat‑resistant elastomer with a spring-loaded lip, it delivers long service life and OEM-grade fit, helping your engine stay clean, quiet, and efficient.
Why you need it ️
Without a healthy front main seal, oil escapes near the crank pulley. That wastes lubricant, contaminates belts and accessories, and can lead to costly repairs. A fresh seal protects timing components and maintains correct oil level and pressure.
How it works ⚙️
A flexible sealing lip with a garter spring maintains steady contact on the crank surface. A micro oil film and directional ribs channel oil back inward while a dust lip blocks debris. Press-fit into the cover, it seals even under heat, vibration, and crankcase pulses.
If the seal fails
Expect oil drips at the front, burning smell on hot parts, belt slip, messy engine bay, rising consumption, and possible low pressure. Prolonged leaks risk bearing wear and timing belt/chain contamination.
Tech tips for replacement ✅
Inspect the crank snout for grooves; use a proper driver; lightly oil the lip; set flush and square; torque the pulley bolt to spec; verify PCV function to avoid overpressure.
