Oil/fuel vapor smell from ac vents

[Payton34]

I have a used oil and gas smell (same odor as the junk in the oil catch can) coming from my ac vents if recirculate is off. Engine bay smells the same. I thought it was the catch can fumes leaking so I removed the catch can but still have the odor. Any ideas?  I check oil cap and connectors going to intake tube.

The next thing I would do is start checking gaskets for any leaks. If there is a leak and the oil is burning off from something hot, that could explain the smell.

Shop just called and can’t find any oil fuel or exhaust leaks. They don’t smell anything so now I have to go pick it up and bring it in when the fumes are blowing through the ac for them to smell it. So annoying
