I have a 1992 xj with the 4.0 liter 6 cyl. . I am getting oil blown ontop of the air filter. It is coming from the tube of what I believe would be the pvc tube coming from the valve cover. It is enough oil saturation, when I change the air filter there is oil residue in the bottom of the air box. Is the engine not breathing properly? Is there a pvc valve? The parts store says no pvc valve? Thanks in advance for anyones assistance.
