2003 Camry consuming oil. >1qt every 1k miles
Greetings!
Facts:
2003 Toyota Camry 204k on it.
Doesn't smoke; doesn't leak oil(on to the ground)
Coolant level is normal and clear
Check engine light on (P420 code, either oxygen sensor/ cat converter)
If it idles for a few minutes, a faint smell of oil will emerge
Appears there might be leaking occurring on the back of the engine, well
below the valve cover.
Trying to figure out what repair will be necessary and how much. Thanks!
