FRONEZER Valve Cover Kit for Nissan 2.5L (2007–2013) — Complete Replacement with Gasket, Bolts & PCV Valve

FRONEZER Engine Valve Cover Kit is a complete replacement assembly designed to restore a sealed, leak-free top end for 2007–2013 Nissan Altima and 2007–2012 Sentra 2.5L engines.

If your Nissan 2.5L is showing oil stains around the valve cover, occasional burning oil smell, or low oil without obvious external leaks, a worn or cracked plastic valve cover and deteriorated gasket are common culprits. This FRONEZER kit replaces OEM part numbers 13264-JA00A and 13270-JA00A and ships as a ready-to-install set with the valve cover, oil filler cap, gasket, spark plug tube seals, bolts, and a preinstalled PCV valve — saving time and reducing parts-mismatch risk for DIYers and shops.

What comes in the FRONEZER valve cover kit and why is it useful?

This kit includes every component you need to replace the valve cover properly, eliminating the need to source separate gaskets, bolts, or a PCV valve. Receiving a matched set reduces installation errors, prevents reused or worn hardware, and helps restore proper sealing and crankcase ventilation.

• One new FRONEZER valve cover molded to OEM specs
• One new oil filler cap and preinstalled PCV valve
• Valve cover gasket plus spark plug tube seals for leak-free sealing
• All necessary replacement bolts included for secure fastening

How will replacing the valve cover improve engine performance and maintenance?

Replacing a cracked or warped valve cover and worn seals prevents oil leaks that can lower oil levels or contaminate ignition components. A fresh PCV helps maintain correct crankcase ventilation, while new seals stop oil from seeping onto belts, coils, and spark plugs — reducing misfires and maintenance headaches.

• Stops external oil leaks and prevents smell or smoke from burning oil
• Protects spark plug wells and ignition coils from oil contamination
• Restores proper crankcase ventilation with a new PCV valve
• Prevents future gasket failures with fresh seals and bolts

Is installation difficult and what should I check during replacement?

Installation is straightforward for someone with basic mechanical skills and common hand tools. Remove the old cover, clean the mating surface thoroughly, replace seals and bolts with the included hardware, and torque fasteners to manufacturer specifications to avoid warping or leaks.

• Clean the cylinder head surface before installing the new gasket
• Replace spark plug tube seals to protect ignition components
• Tighten bolts incrementally in the proper sequence and torque
• Inspect PCV hose and connections for wear while replacing the cover

Who is this for: The FRONEZER valve cover kit is ideal for Nissan owners and mechanics who need a reliable, OEM-matching replacement for worn or leaking valve covers on 2.5L Altima and Sentra engines. It suits DIY enthusiasts doing scheduled maintenance or independent shops looking for a complete, time-saving replacement that includes all necessary seals, bolts, and a preinstalled PCV valve. Backed by a two-year warranty and 30-day return policy, it’s a practical choice when restoring proper sealing and ventilation at the top of the engine without hunting down individual parts.
