Just got a new-to-me 2021 2500 Cummins with 53k miles. Checked the oil filler cap and I’m seeing a bit of smoke coming out plus the cap wiggles a little bit. Is this an acceptable amount of blowby or do I have a problem? Is this just normal ventilation and the cap movement is engine vibration? This was at a fully warm engine at idle.
