oil leaks on 30cc 4-cycle?

Why is my new string trimmer Model # C430(ZRRY34420) spewing oil? Purchased new as a reconditioned unit. Gave my older Ryobi 2-cyle to son.

Have same problem. Replaced both check valves now excess pressure from crankcase is blowing hose off of fitting. Wondering if I need new hoses or is the excess pressure due to something else.
