Description

This specially machined aluminum fitting replaces the stock PCV valve on top of the Subaru FA20, FA20F, FA24D, FA24F, and Toyota 4U-GSE engine blocks and will allow the connection of a -10an hose for a custom set up.
This black anodized 6061 aluminum fitting converts the threaded hole in the block to a straight thru -10AN male fitting. The fitting has an overall height of 3.1″.

Installation Notes:

• Always apply a small amount of PTFE thread sealant before installing. First, hand tighten the fitting. Then, use a 7/8″ deep socket wrench to spin the fitting another 1.5 to 3 turns.
• This fitting deletes the PCV valve. If connecting this to a catch can that breathes back into the intake manifold, a PCV valve must be installed somewhere in the system to meter the airflow into the intake manifold and prevent any reverse airflow into the crankcase. A PCV valve must be used: a check valve cannot be used in place of a PCV valve.
