PCV seemed fine. I replaced it @ 62k and the car has 70k on it now.

It seems more logical that it would be a tube from the DPFE sensor, and I'll check that tomorrow when it is light out.

It does seem to be lower in the engine where the DPFE is, but that is just where it sounds like it is coming from. I'll check those tomorrow some time.

I did replace the air filter with a stock K&N air filter, but the noise I am hearing is definitely a hiss, and doesn't change at all really with throttle.

I dare say it almost sounds like it's coming from the LIM or something, but a hose seems more logical.

Thanks for the quick response.
