Thanks everyone for the tips! Really looking like the carb tuning (or nature of these carbs) is the culprit. I’ll look into it further this spring. In the meantime, the leaks needs to be addressed.

I meant that the overfilling could be causing the engine to burn oil that’s risen too far and cause the smell. Sounds like that’s not the case here though. The leaks are an entirely different issue that I was just pointing out in case those could be burning up at the point of the leak and causing the smell. I probably didn’t explain this well, but appreciate the tips!

I recently bought a '73 240z (super excited to be part of the community btw). Every time I start up the car and am standing outside next to it, the smell of the exhaust quickly saturates my clothes and even leaves my skin smelling like the exhaust fumes requiring a shower and to immediately throw my clothes in the wash. Is this normal on these cars? Some additional context that might help: Everything on the car appears to be stock except for dual Weber carbs There's a very slow leak of transmission fluid coming out of the bell housing area (about 1 drop every 30 min) There's an even slower leak of coolant, dripping onto the starter (at least I think it's the starter) I checked the oil (after letting the engine run for 10 min and cool for about 5 min) and it appears to be filled slightly higher than the max line I had a classic mini not too long ago that had a similar issue only after overfilling the oil so my first thought was to drain some of the oil and let the engine run for a bit to burn off any excess that's still where it doesn't belong. However, figured it might also be due to the fluid leaks being burned off. Or simply that these cars have very smelly exhaust fumes and everyone in the 70s smelled like fumes after driving their car, but I'm betting this is not the case. Happy to provide photos of anything that might help troubleshoot the issue.

Ahh, makes more sense than the messy adhesive that I was going to use. I assume you just tape the weather-stripping to the back of the new panel and then secure it to the hatch with the OEM (or replacement) screws & plastic rivets and that should eliminate any gaps for fumes to pass through. Thanks!

Just got a 240z and am having the same issue. Yours and @Zed Head 's comments made me check this hatch panel and yep, completely warped. Ordering a replacement panel now, but any suggestions on a particular sealant to use, or types of sealants that work best for interior trim paneling to keep out the elements? Edit: I just ended up ordering some Permatex Silicone RTV. Hopefully that will work fine but open to others that people find works well/better.
