Check your intake tubing to make sure that there isn't a crack or leak in it. Have you modified your intake tubing/piping at all - not to be mistaken for intake manifold?
Sorry to revive this..I forgot that I posted it. Everything is completely stock. It whistles after I shut down the engine for a couple seconds. It seems to be coming from the passenger side by the IM. Also, I have been going through oil like a mofo (1.5 qt. mobile 1at 2200k miles)without any smoking issues. I read up on PCV valves and have concluded that it may be contributing to the oil consumption. I pinched the hose from the valve to the IM and there is no ticking. I think it is still the factory valve (100k), so im gonna clean it out. But I'm wondering if a clogged PCV could be causing the whistle? Any opinions?
