i have a johnson 15 hp 4 stroke that lost all power and stalled but did restart but now has an oil leak that looks like it is coming out the air intake at the carb i assume that the oil is coming from the crank case breather tube but what could cause this
 
Re: oil leak out air intake

Sounds like the crankcase is overly pressurising Check your compression on each pot. Maybe some mechanical damage or, if there is one, the EGR valve may be stuffed.
