I have 2 PCV the one on the passenger side is not getting any vacuum. when I but my finger on it it should make a sucking noise. where does that one ling go to under my intake. Please help thank you

 

The line on the right (passenger) side rocker cover is the crankcase vent line. It is connected to the throttle body upper right port. It supplies filtered fresh air to the crancase so the PCV system can operate. There should be no suction on the line from the throttle body, but there should be a slight vacuum at the hole in teh rocker cover. If you cover the hole in the rocker cover with your thumb while the engine is running, the vacuum should increase gradually if the system is working properly.
