    Question What's up with teh burning oil smell on these 4.6s?

    My other car did the same thing and I thought it was just fuggered up. Well, this '01 does the same thing. I think I've narrowed it down to the cheap rubber elbow that comes off the front of the plenum, makes a 90* bend and goes back into the PCV Valve on the passenger side head. After a drive, it's somewhat mushy to touch it. Is there really that much oil coming out of that valve and into the intake. The other car never used any oil between changes and this one seems fine so far.

    There are no other leaks anywhere. WTF? It just drives me nuts.

    Mine is noticable when I run an off road pipe. As Frank Tedesco up at PRP made a comment to me last year about smoke from one tail pipe when launching. Both my 2000GT and my current 2004GT have done this. Doesn't seem to use much oil when it happens as I never really need to add anything when I check.

    I run a catted pipe now and it is not noticable. The biggest thing is turning the high rpm's and the cams are creating a nice oil mist in the valve covers which easily gets pulled thru the pcv system. I picked up and air/oil seperator from Jegs that I plan the use to keep any further oil from being pulled into the intake system and then burned off. Not good for making power if oil is burning. My spark plugs seem to stay clean so I know it's very little being burned off.

    thanks, Ares. Are you going to put the a/o seperator on the PCV hose on the pass side or driver's side? or both? and where are you going to mount it. I would think somewhere on the firewall, but these damn things got so many hoses running around it looks like chit as it is.
