Intake Question

vertigasen said:

Hose A is the hose from the CAI to the drivers side valve cover. Hose B is PCV (Positive Crankcase Ventilation) to the intake plenum.

They are part of the engines pressures and vacuum system. Metered air comes in past the MAF on the CAI. It then goes into Hose A and is sucked into the drivers side valve cover. Air then moves through the engine and is ejected through the PCV valve on the passenger side valve cover, then into the intake.

It shouldn't matter much about hose A being pressed down on. If it was me, I would get a thicker piece of hose and put that where hose A is so that it isn't smashed like it is. For Hose B, I would get a new elbow so that it does not squeeze. That does not look like the factory elbow, so if it making a sucking noise, it might have a leak. In fact, that looks like the correct hose, but way too much hose after the elbow. If you get the factory part, you will notice it just connects to the PCV valve, then a 90* elbow into the plastic hose. There should be a little "hose stop" ridge that will fit perfectly up to that elbow. If you are hearing air "sucking" around it, then it is more than likely leaking. That could let unmetered air into your engine and cause a lean condition (not good).
