Guys i have a picture here what is this hose? I had my head gaskets replaced and now I'm noticing wires and hoses not conected. The engine light has not gone on and the car runs like new but still bugs me when stuff is not connected. Anyways....this particular hose is cracked at the end and won't stay on what is it and will it affect my oil pressure which is at like 20-40???

Thanks for the help

 

That is the hose that connects to your pcv (positive crankcase valve).Get a new one if it is cracked. Probably $10 from GM. Try Autozone or Advance, etc... It shouldn't mess with your oil pressure.

 

That hose does not connect to the PCV valve. It is part of the PCV/CCV system, though. It is the fresh air inlet hose for the system, going from the throttle body to the RH valve cover. The PCV valve is on the LH side, center of the intake manifold.

 

yup, your right. I spaced it.
