Stock blow off valve

[DMW]

I just bought my '04 GT from the original owner. I was driving to work this morning and I can hear a faint psssht sound when I nail the throttle and let off at low speed. Is this how the your guy's Cruisers sounds stock? If not, I'm wondering if the previous owner put some sort of aftermarket blow off valve on there. [:I] It's not a loud sound, but definitely noticeable.

The "pssssssssst sound" you hear is normal for a BOV, although it is not very noticeable (sometimes people don't know what to listen for) with the stock BOV that vents to the inside. However, if you have an aftermarket Mopar BOV (that vents to the outside) it will definitely be louder and look like this (blue metal part with two holes):

Stock intake? I didn't hear mine until I put on my K&N FIPK intake, now it's REAL noticable.[:I]

If the intake appears stock, open up the airbox, remove the filter and see if the white donut is still there. Getting rid of the silencers will increase the engine sounds, including the air release when the throttle is released.

I checked the other day and the white donut is in there. There was also some oil sitting on the bottom of the airbox as well.

Oil in the bottom of the air cleaner assembly is normal and why some have put on a catch can.

What is a Catch Can?

[Gary04GT]

A "catch can" is optional and IMHO is really not needed. I clean the oil out of the air box every 3-5K miles when I change my Mobil 1 synthetic oil and replace the K & N oil filter--no problems whatsoever.

a catch can on the intake side may not be needed, but it is deffinetly? needed on the PCV side
