I have a Hammerhead Twister 150 and it has been blowing oil out of the head. The oil comes out of the head through the tube that goes into the filter box. It is blowing quite a bit of oil out. I thought I may have some broke rings and changed the rings but still have the same problem. Is there somewhere else on these GY6 motors that releases air pressure or is it all supposed to come out the head? I thought that there may be something stopped up making it push oil out the head like this. Could it be a faulty head cover or is this a common problem due to a bad setup on these motors? Just wondering if anyone else has had this type of problem or heard of anything like this.
