So, as a few of you know, Nissan replaced my engine (long block) a WEEK before warranty was up. Good news, but now something is weird.

Ever since the new engine, when I shut the engine off, I hear "ticking" from the exhaust. I know this is normal, its the catalytic converters doing their thing.

But my concern is, every time I go up a hill, or under load, my car produces a rotten egg smell and NEVER has it done this before. Why now from a new engine??? Didn't do this before.

Did they put New Catalytic converters in?

If so, that is likely the issue.

Hydrogen sulfide is the “rotten egg smell” that you mentioned. It is typically caused by a rich fuel mixture. The catalytic converter may be faulty or you may be running rich. It may also be the new cats getting a few heat cycles on them. My advise: Report it to Nissan to make sure you will be covered in case the smell does not go away over time.

Wow, good to know. As far as I know, they never replaced the cat(s), but a week before the engine transplant, they did a test on them (cats), for some reason. I'll check to see if they're new. Don't want this car running rich
