Its blowby from the crankcase PCV. They have a TSB on it and a revised front valve cover for the issue.
My 2012 Explorer is out of warranty. It has the oil migration problem with the 3.5L V6. Does anybody have the part number for the redesigned valve cover. I have been cleaning oil out of the air filter housing and air intake tube at every oil change.
Thanks!
I assume you are not referring to your 2004 Explorer that shows in the margin?The tubo engine has the smoking problem. They changed the left valve cover. Mine is non turbo it has oil in the air box pcv seems ok the baffle in the valve cover seems to be the culprit.does anyone know if there is an improved valve cover design or if that ford rep. Is available to give us an answer. I think with 22 TSB s, we should get the procedural repairs for free instead of the dealer telling me to bring it in and charging me. Thanx. And special thank to the guy that listed some of the TSB s. You have to know someone, work for ford, or pay for this stuff. 95,04,12 explorer owner. 95 was the best one yet.
Issue resolved! The problem stemmed from the design of the 2011-2012 valve cover vent tube that connects directly to the air intake tube. This was the first occurrence our dealership has encountered and as such they contacted the Ford Hotline for guidance. Ford advised: replacing the valve cover to incorporate the latest design of the vent tube which now has an internal baffle to prevent oil from migrating all the way up to the air intake tube and to the throttle body. Valve cover was replaced and we'll monitor it regularly from now on.
2012 Explorer. Just discovered oil in the intake and on the air filter. I cleaned the intake tube and ordered some air filters online. A week later, I finally got the new filters delivered and installed one... more oil had already accumulated in that time. From what I have read, there is a TSB on this.... maybe?
Ford TSB #ASI-32211
NHTSA Reference #10053358
can anyone confirm the TSB on the redesign valve cover
my next service is coming and would like to discuss this issue to the service advisor. thanks
I can now confirm this. My wife just had her valve cover replaced.
I had discovered oil in the intake. Took vehicle in and they replaced the PCV valve. A few weeks later I found oil again. We took the explorer back in to service and told the rep about the TSB. They pursued that course of action and had to order the valve cover which was on back order. It came a few weeks later. They replaced it 2 days ago. The alarming thing is I checked it out today and saw oil in the air intake again... I'm hoping it was either residual oil left in the system or the tech didn't clean out the intake. I wiped it clean and I'll check it out in a few more days.
