Macgyver 90 #1 Posted July 14, 2016 I have 2 onan engine blocks one has the newer crank case breather it is metal and goes straight up the other is plastic and on an angle. Question is how do you remove them? Also one block was a vertical shaft engine but looks identical to the horizontal block. Is there a reason it can't be used with the horizontal crank & oil pump?
