RB Oil gallery threaded bungs.
A much needed product when building a Nissan RB engine.
The main oil gallery in all RB/RD blocks is sealed from factory with a steel straight walled plug, it needs to be removed for the gallery to be cleaned before a build.
We've designed a set of custom size threaded oil gallery block offs and have included a tapping tool in the kit, no drilling required before tapping other than drilling a hole through one bung to smack the other side out with a rod. This product features a 9/16-18 UNF Thread, and we highly recommend utilizing thread tape for a secure seal when installing it into your motor.** Critical operation notice: Ensure proper installation depth to maintain continuous oil flow to the engine bearings**
