oil in air intake manifold

[ldruth61]

2012 SE, 3.5 L V6 - I keep getting oil in my air intake manifold between filter and throttle body.  I was reading a while back and saw that a bad PVC can cause this so I replaced it. But still doing it. Then I read excessive engine oil pressure will be created and cause extra oil to push through the PCV valve and into the air intake. You can tell it's coming from the breather tube on the left side of intake manifold that goes to engine. Could this be happening from me using my manual shifter when going downhill to avoid excessive braking? It causes engine back pressure when Rpms go up and engine shifts down while going down the hill. Any thoughts about that being the issue or something else. Engine is well maintained and serviced regularly by me.

Thanks for help

There was a Special Service Message 44354. "2011-2013 Edge, Explorer, MKX, Taurus, MKT and FLEX - 3.5L/3.7L (Ti-VCT) - Oil in the Air Intake. Some 2011-2013 with 3.5l or 3.&L variable cam timing engine built on or before 3/31/2012 may exhibit engine oil in the air systems may be caused by an accumulation of oil in the left hand valve coverbaffle migrating through the fresh air intake carnkcase ventilation (PCV) system.

There might be a more clear documentation out there, but this is what i found quickly.

When I changed spark plugs on my wife's 3.7L Mustang I found oil in the intake - I replaced the PCV valve and installed a catch-can and no longer get oil in the intake.

 

I doubt that the engine braking would cause this.

1004ron -What kind of catch can? So you remove the breather tube from the air intake manifold and put a can on the end of it?

thanks

omar302 Would this be something the dealer would due as a recall type of thing or will I have to pay for it.

I have the JLT catch can installed.

Only if the vehicle still has a running warranty. Original bumper to bumper warranty, Powertrain Warranty or an Extended warranty. Otherwise no.

as 1004ron suggested, a catch can is the easiest fix to this, in the absence of a warranty
