The Rocker Cover covers the top of the Cylinder Head including the Rocker arms and valvesprings. The rocker cover is painted Datsun Blue, which is a darker blue than the air cleaner. The rocker cover is also known as a valve cover or tappet cover.

Installation

They are prone to leaking like most stamped steel covers. Biggest problem is over tightening. They should be finger tight and retightened at least every oil change.

  • Hammer the flange flat before installing the gasket.
  • Remove all traces of old gasket and sealer.
  • Do not use sealer. Clean & flat will prevent leaks.

The black rubber gasket lasts forever. The cork gaskets tend to tear on removal of the cover.

Tighten all the valve cover screws finger tight. Then go around and re-tighten finger tight. After the engine warms up, finger tighten one last time. Instead of using a wrench which will overrtighten, use a Phillips screwdriver. Use thumb & finger to tighten; using the palm or fist to reef on the screwdriver will tighten too much and distort the metal flange.

Loctite Threadlocker Blue might help. I've never used it ... but the screws do get loose.

Gasket

The same valve cover gasket (packing) fits all A10/A12/A13/A14/A15 engines. Nissan made several specification of material but the shape and dimensions are the same. The black rubber type is generally reusable, while the cork type often breaks.
