Plugs replaced less than 3000 miles, seals replaced last year. Coils testing ok. This car regularly (annually since I had it, 3 plus years) burns out the oxygen sensors on the nearside exhaust and has also burned away the cat, also replaced. Now upon replacing the sensors again the nearside mixture is registering weak.

Have you replaced/upgraded lower breather elbow?
What are the error codes you get? Maybe it's time to change repair shop? You sure all the seals, including inner boss seals were replaced?
