Oil/Water with Yellow Sludge Coming Through PCV Valve on Valve Cover on a 2.2 06 LT
I have been having a problem with my cobalt for several years where the pcv valve is filling the tube that goes from that to the intake up with sludge that seems to be a mix of water (most likely condensation) and some oil. I have since put in a Oil catch can to hopefully collect most of the sludge from reentering the intake and causing problems. The catch can seems to fill almost every month with a lot of watery yellow sludge.
Would anyone know of such an issue or what could be the culprit ? I thought it was my valve cover inlet or gaskets on that and changed the valve cover and gaskets a few months ago but still the same problem.
Let me know if you have any ideas on what could be the cause.
