Is the oil catch can/seperator (black square-shaped box in front of valve cover) necesary? Can I remove it and replace it with a catch can that doesn't recirculate back into the motor? What exactly does it do and does it effect emissions? Thanks.

Anybody??? Please???

Here it is in the Archives:
"PCV MODIFICATION SO NO OIL WILL BE PRESENT IN THE MAF:
have you tried modifying your PCV system? i vented mine so that the part from the VC goes into a T right below the catch can, and the top of the can goes to the intake stream. i plugged the 2nd nipple with a cap and clamped it down. this makes it so that oil that may enter the PCV system (there is, after all, over 200HP worth of air moving quite rapidly through the inlet tube, creating a VERY powerful vacuum) expands in the catch can, and is ultimately very hard to enter the intake tract. this is especially true for cars that spend a lot of time in hard right hand corners, as oil will pool up in that side of the VC and get sucked directly into the intake."

Bob, PM me your addy...I'll give you the details on the Venom.
