Oil tank breather pipe

[43scotty]

After removing the air box I noticed oil deposits on the intakes for cylinders 1,2and 3., I think the oil is somehow being sucked in from the breather hose that connects between the air box and the oil tank
Can I remove the hose , blank off the air box side and install some sort of small air filter on the oil tank end ?
Has anyone experienced similar and would I cause any problems doing this ?

Thanks for the feedback , never sure about the oil levels but will double check
