Why Choose iFJF?
The QR25DE engine is reliable — but its valve cover gasket is a known wear item. As the gasket hardens from heat cycling, oil seeps onto the exhaust manifold (causing a burning smell) and into spark plug wells (causing misfires). Our iFJF replacement cover solves this at a fraction of the dealer price.
Installation Tips
- Disconnect battery before starting work.
- Remove ignition coils and PCV hose for access.
- Clean mating surface thoroughly with brake cleaner.
- Torque bolts to 74 in-lbs (8.4 Nm) in spiral pattern from center.
- Budget 45-90 minutes for DIY — straightforward bolt-on replacement.
