Blow by?

I'm looking to purchase a 99 New Holland 555e 4x4 with 2800hrs. I went over it thoroughly and all fluids look good. No leaks, no noises, no smoke. I decided to take off the oil fill cap while running and no oil squirting or smoke but there is some air coming out. It was up to operating temp, pressure was good on gauge.... is this a bad sign or normal?

Thanks, Daniel
