Multiple O2 sensor failure Sign In

After receiving service at my local dealership my valve cover was severely leaking oil. 3 quarts in 3 days... So, oil was leaking everywhere and was potentially being burned as well. 2 O2 sensors failed after the oil leak started but before they fixed it. Of course, they say it is unrelated. I have received conflicting opinions so far. what does the group say? Thanks in advance for your help!

Never heard of a oil leak ruining an 0/2 sensor. The business end of it is inside the exhaust pipe.

I'd be very surprised if 2 sensors failed at the same time for any reason.
