Oil pooled on intake valve??? Related to Recall?

Okay so your even more unlucky. Hahaha.

Considering your cats are falling apart and you aren’t burning oil then I’m guessing you are running really rich. Maybe a bad O2 sensor or something or maybe an exhaust leak is making the car think you are lean so it’s dumping lots of fuel to compensate.

Cranking it over I noticed this. Stuck Valve??

First question I would ask is how did the oil get all the way back up in the manifold? Did it back fire? or is it coming from a vent tube?
With someone else turning the key is that valve moving? or is it stuck? Could just be up on the cam.

Yup.

They open and close together.

Time to bring it in, the dealer/manufacture may cover hauling. Call them and discuss, and describe your symptoms and see what they say.

The issue we see here may not be related to your valve springs; however the sounds could be. Regardless you have an issue, and the issue likely can be fixed now as part of the recall for much less.

Too lazy to write it again.

Didn't seem like a mystery to me (other than the oil part) since his first post reads almost word for word like the recall notice. Almost like a book made into a movie.

Lost a rocker?

Depends on which one isn't moving. Closed stays closed you lost a rocker. Open stays open you bent a valve.

Broken spring usually leads to a floated valve that finds the piston and tweaks. Gets stuck in one spot, bound in the guide.

Or worse. That amount of oil looks worse than a bad guide seal imo.

Yep exactly what it is. So valve spring is good! Its somewhere hiding behind the cam. I can jiggle it around. Surprisingly the cam seems pretty much unscathed. I was expecting a lot of marring and what not.

As for the oil Im guessing rocker fell off first -> Intake valve stuck closed -> rich afr in cylinder -> a lot oil blowby -> oil recirculated into intake.

Calling the local dealer tomorrow to see if its worth the chance of spun bearings for them to fish it out.....

Rockers can’t really just fall off, they’re stuck between the cam and valve. Something has to move for it to come out. Considering the cam isn’t exactly flexible, that really only leaves the valve.

The pin holding the roller is known to come apart on early builds. Mid 2014 the valves (longer), rockers and pivots (smaller oil hole for more lift) were revised to combat this problem. So yeah they don't just fall off, the roller comes loose and then they fall off.
