According to parts photo's it is a threaded screw so should be able to undo with a screwdriver, but it is a very narrow slit for a crew driver, and it is also a long slit. Anyone got any tips on how to remove this.
I see some people have had PCV' valves missing, others with the ball/spring installed incorrectly. Which way is it supposed to go. Assuming it needs to draw air INTO the engine, then the spring would go in first, then the ball, and then the nipple, is this right?
