J Replace OE Replacement S14 240sx KA24DE Valve Cover Gasket

The KA24DE is famous for valve cover gaskets that harden and seep oil down the side of the block and onto the exhaust manifold, producing that burning smell after a drive. This J Replace OE replacement valve cover gasket for the S14 240SX with the S14 KA24DE is a new gasket to seal the cover properly again.

Gasket Details

• OE replacement valve cover gasket
• Made for the S14 version of the KA24DE
• Seals the valve cover to the cylinder head

Fitment

Nissan 240SX S14 models equipped with the S14 KA24DE. The S13 KA24DE uses a different valve cover and gasket, so match the gasket to the generation of engine in the car, especially if the engine has been swapped between chassis.

Install Guidance

Remove the valve cover, scrape away all old gasket material and oil residue from both sealing surfaces, and clean the groove in the cover. Fit the new gasket dry or with a light dab of sealant at the corners where the cam caps meet the head, then tighten the cover bolts gradually in sequence from the center outward. Overtightening squeezes the gasket out of its groove and causes the exact leak you are trying to fix. If the spark plug well seals or the cover grommets are hard and cracked, replace them at the same time.

Maintenance Timing

A valve cover gasket is a quick job that pairs well with a valve lash check or a cam cover cleaning, and it keeps oil off the manifold where it can smoke and crack the paint.

With limited availability and frequently increasing prices on new OEM parts, J Replace offers a quality alternative at a steady price.
