Out of warranty in my case... I'm almost 100K miles. I have issues with a single screw (top leftmost), which is leaking oil and is most likely snapped anyway. I'm replacing the darn screw. If I make it worst, so be it, then I'll take it to an indy to fix the thing. If I stop the leak, then great.+1 I just went through the same rigmarole a year ago, at ~30k miles, i.e. first engine-out repair by P dealership mechanic resulted in a faulty re-install, apparently an issue with the seals, that led to an even worse leak. The 2nd engine-out repair by P dealership master mechanic finally fixed it, though there was some other seal on the top of the engine that they had to repair before giving it back to me 100% repaired. All work done under warranty. I would highly recommend NOT wrenching on this as a DIY. Apologies if the car is out of warranty.... didn't read far back in thread.
