I had the wonderful timing chain issue with our 2007 Saturn Outlook XR FWD. This in turn has caused a whole headache of other issues I started in another post. But to sum it up the head also was messed up so we ended up replacing the motor. After driving it for maybe a half hour after we got it back the check engine light came on now saying that the catalytic converter was bad. When the dealership pulled the codes they said they thought it was from the timing chain going bad. We went through the whole thing with GM customer "service" again and finally heard back from them that they wont replace the catalytic converter because the brake master cylinder was leaking and I need new brake pads and that is what caused the catalytic converter to go bad. After replacing the motor they said nothing about my master cylinder leaking. Has anyone seen this happen before or could someone explain to me how this could even be possible? It does not look like the exhaust runs anywhere near the master cylinder and I don't even believe them that it is leaking. I see no fluid around it at all.
