Why Choose iFJF?
The VQ35DE is one of Nissan's most popular V6 engines, powering millions of Altimas and Maximas. Its valve covers are a known maintenance item — gasket degradation leads to oil in spark plug wells, misfires, and burning oil smell. Dealership replacement can cost $500+. Our iFJF set provides OE-quality sealing at significant savings with pre-installed gaskets for faster installation.
Installation Tips
- Remove the upper intake manifold (plenum) to access the rear valve cover.
- Replace the intake plenum gasket during reassembly to prevent vacuum leaks.
- Clean all mating surfaces with brake cleaner and a plastic scraper.
- Torque cover bolts to 74 in-lbs (8.4 Nm) following factory tightening sequence.
- Budget 3-5 hours for a first-time DIY mechanic — the rear cover requires more disassembly.
Frequently Asked Questions
Q: Will this fit my 2005 Nissan Altima 3.5L?
A: Yes. Direct fit for all 2002-2006 Altima with the 3.5L V6 VQ35DE engine.
Q: Are both front and rear covers included?
A: Yes. This set includes the front bank cover (13264-7Y000/264-984) and rear bank cover (13264-7Y010/264-985) with pre-installed gaskets.
Q: Why does the VQ35DE valve cover leak?
A: Over time, the rubber gasket hardens from heat cycling, losing its ability to seal. Spark plug tube seals also degrade, allowing oil into the spark plug wells.
Q: Is this a difficult DIY job?
A: The front cover is straightforward (1-2 hours). The rear cover requires removing the intake plenum and is more involved. Budget 3-5 hours total for a first-time DIYer.
Q: How does this compare to OEM Nissan?
A: Meets the same material and dimensional specifications as the Nissan OEM parts (13264-7Y000/7Y010) at 50-60% savings.
Q: Do I need to replace the intake gasket?
A: Yes, we strongly recommend replacing the intake plenum gasket when reinstalling the manifold. Old gaskets can cause vacuum leaks and check engine codes.
