Oil in air intake.

[SHOdded]

I would personally check the belly oil pan cover and  see is there any evidence of oil,sometimes it could be simple such as an oil drain plug loose or bad gasket,or oil filter loose which would explain the lost oil.

True, we always forget about the basics!  Plus it's good to take a peek at the undersides of the engine once in a while.

I have witnessed the same issue with my 13. Not as much oil consumption though. A dirty or restrictive air filter will cause the problem to get worse, also any restriction to the PCV system can also make it worse and lastly too much oil in the pan can also cause a similar situation (over fill). I took mine in when I had a similar issue and the dealer said it was normal (I had 45K KM on mine at the time). I am still not sure what is normal, all I know is that it can accumulate in the CAC, and if you get on it on the expressway it will suck all that out of the CAC and into the intake. Risking vapour lock or just a shudder (which will be logged by the car as several misfires). Again this happened to me in the past (the shudder). A turbo upgrade and meth are my next mods to my ride, the OEM turbos can be a PITA when it comes to this issue, the dealers and Ford are not willing to do anything about it unless its really bad. With the stock tune it is difficult to replicate these conditions as it doesn't suck/blow as hard as good 93 tune. I know that the F150's have had similar issues with both water and oil in the CAC causing a shudder at WOT in higher gears (easier to replicate different turbos/cac) I would keep an eye on the level in the CAC as mentioned by SHOdded.

I just mentioned this in a flex forum... when I disconnected the charge pipe to get to my driver side rear plug, I saw some oil too. I chalked it up to be blow-by of some sort. I don't think its any area of concern. Also @Rich - I hope you change your oil more than every 20k

Oh yeah, the 20k is total miles we've put on the car. Started at just over 3k change, then worked up to 5k where it just felt to long even though the oil looked good. Going back to 3k intervals and since I just tracked the car last weekend, I changed it this time just over 1k on it. Will continue to change oil after each track day or 3k.
