Another 2013+ leaking valve cover...

After running my still stock car for a few days after getting it back from having the leak fixed I noticed it felt slower...not slow but not like it should. I checked the LOR thinking maybe they reset the computer but that was fine at -1. I then looked at my other Torque gauges and realized the Max boost the car had seen over the last two days was about 5 psi.  I immediately thought that was odd because I know I had floored it earlier. I scanned it with torque and it said no DTCs but the PID that reads how many DTCs said one was set. I fired up FORSCAN and it immediately pulled a P0299 which is an underboost condition. Great... I thought. I checked all the piping and clamps but couldn't really find anything. I reset it and took it for a drive but same behavior and the code came right back. Popped the hood again and noticed the nut holding the top charge pipe was missing but whole annoying didn't see how that could be my problem. I started checking for loose connectors and then I saw a small connector hanging down and it was pretty clear it was unplugged. I honestly don't know now what this sensor is called but I think it compares boost levels from the intake and the manifold or maybe does something to the wastegate ultimately?? (Anyone know for sure) its the one in this pic with all the small hoses and clamps coming out of it right up front. (Not the MAP sensor you swap out for a tune).

Once I plugged it in and cleared the codes it ran great and all my boost is back! I've had great service from this dealer in the past so maybe I just got a bad tech...yikes.

Somewhere out there there is a stock Dodge Charger R/T that thinks his car is way faster than my SHO (happened earlier in the day which is what got me wondering if something was wrong).  I want a rematch! :)

Makes you worry what else this guy touched!
 
Good catch!  I have anxiety when I have to bring my babies to the dealers, especially for overnight visits.  Just don't trust other people.  But I hate working on cars, so I suck it up.
 
Just stopped by the dealer and they were professional and apologetic...got a free 6mm flange nut (takes a 10 mm socket) and a cold diet coke for my trouble. Hopefully all else is fine!
 
Ecoboostsho, learning what that sensor does is good information to know and congratulations for finding the issue and correcting it.

Thanks! It is officially called the "Boost Solenoid" on Fordparts.com and it is obviously attached to the wastegates so it definitely controls boost levels.  Part #9K378.
 
HMMMM....i am out of basic warranty. I do have the useless CPO certified warranty. Ford said they need to replace the rear(right) valve cover, gasket, pcv, and new version oil separator. Under Certified warranty the valve cover and gasket are under warranty, BUT not in my case. Nothing wrong with valve cover or gasket but the oil separator which is not under warranty. The new revision oil separator does not fit the old valve cover, so they have to replace it and I have to pay for it. said cover was 339, pcv was 9.00 and oil separator was 89, total with labor 750 plus tax etc. I called Ford Customer care to argue but got no where except a three way shout match with ford rep and dealer rep, bottom line not warranted. I copied the part numbers from this thread...
currently Tasca parts...
AA5Z-6A785-F 60.99 SEPARATOR
AA5Z-6A666-D 4.91 PCV
AA5Z-6582-E 129.99 VALVE COVER WITH GASKET
I will do my self...but not sure why my RXP dual system catch can did not catch all this...
 
With smokey exhausts,  I believe the problem lies entirely on a bad oil seperator.

For whatever reason, its unable to relief pressure thus causing an increase in oil pressure(which end up going through the turbo seals), and also causing increased pressure in the valve cover.

Any catch can will not work simply because theres nothing to catch with a fault oil seperator.

Quick fix IMO woild be to replace it with the old version, keep an eye on it because it would eventually have to be replaced.

My SHO smokes while idling from time to time also and am out of warranty.

I don't see anyway a bad oil separator can increase oil pressure...If the oil separator is completely clogged and crank case pressure builds from combustion gases that blow by the rings.

If crank case pressure is not relieved your oil drain for the turbo will also become pressurized as it's part of the crankcase and that can cause the turbo to not drain as well which can cause oil to leak through the seals from the CHRA of the turbo.

I've been through this with precision turbo....Not sure about garret turbos but most are similar...The center sections are usually metal snap ring seals so there is really nothing to go bad...Precision would rebuild turbos from customers that insisted the seals were bad but they would also advise that there was a drain problem or crankcase pressure  problem or oil feed was oversized

Your oil feed is stock and your drain is OEM so those are good but if your separator is bad and your crankcase is pressurized that is usually bad.
 
That's BS!  Oil leaks are covered under CPO.  It's their problem, not yours, if additional parts are required!

At the very least, I'd make them fix the leak.  Even if that meant using the original parts.  It's required under CPO to return the car to factory (non-leaking) condition.
 
Just looked it up.  Seals and gaskets as well as valve covers are covered under CPO.

I would be livid and mention your further calls to the EPA, NHTSA, and DOT regarding your under warranty vehicle that is leaking oil and the environmental hazard that it's creating.
 
It should have an internal pressure relief valve inside the oil separator.
I would remove and inspect,clean the oil separator using some simple green .

Remove the PCV valve turning it counter-clockwise.
Remove the 2 bolts using a 8mm socket and one clip to gain access. Z
