2 on top one on tube and one on oil cap
One is for the PCV valve, the other is just a vent.
There is a vacuum controlled valve in the snorkel tube air inlet on the cleaner. With vacuum, warm air comes up from around the exhaust manifold. With no vacuum it moves to let in outside air.
The thing on the cleaner cover is a bi-metal temperature sensor that controls the vacuum to the snorkel valve.
The tube to the oil filler cap supplies filtered air to the drivers side valve cover. This replaces the air sucked out of the passenger side valve cover through the PCV valve.
Thanks guys about to do sum riging
Vac adapter kit and the breather kit later looks ok to me the parts store only had 5 1/8 so I rolled neck a slight bit
