Genuine Nissan OEM RB20 RB25 RB26 Exhaust Rocker Cover Gasket – 13270-58S01
Keep your Nissan RB-series engine properly sealed with a Genuine Nissan OEM Exhaust Side Rocker Cover Gasket, designed for compatible RB20, RB25 and RB26 engines, including the legendary RB26DETT found in the Nissan Skyline GT-R.
This genuine Nissan gasket provides the factory-style seal between the exhaust-side rocker (cam) cover and cylinder head, helping prevent engine oil leaks and maintain the correct sealing performance of your engine.
Over time, original rocker cover gaskets can become hardened, brittle, compressed or damaged due to age and repeated exposure to engine heat. This can result in oil seeping around the rocker cover, leaving unwanted oil residue throughout the engine bay.
Replacing a deteriorated gasket with a genuine Nissan component helps restore the original sealing arrangement and provides the correct fitment expected from factory replacement parts.
Whether you're completing an RB26DETT engine rebuild, refreshing an RB25DET or addressing oil leaks on your RB20, this genuine Nissan exhaust rocker cover gasket is an excellent choice for maintenance, repairs and OEM restorations.

Replacing Both Rocker Cover Gaskets?
RB-series engines with separate intake and exhaust rocker covers use individual gaskets for each side.
This listing includes the exhaust-side rocker cover gasket only. If you're resealing both rocker covers, the matching intake-side gasket must be purchased separately.
For a complete reseal, inspect the condition of the rocker cover bolt seals, rubber grommets and other associated sealing components during installation.
Important Installation Information
Ensure the rocker cover and cylinder head sealing surfaces are clean and free from old gasket material before installing the replacement gasket.
Follow the Nissan factory service manual for the correct installation procedure, tightening sequence and torque specifications. Apply sealant only where specified by the manufacturer.
